▼ Background: Iron deficiency, anemia, and iron excess have been associated with altered hearing functions in children and adults. Animal studies suggest that iron deficiency during pregnancy negatively affect fetal auditory development. The relationship between maternal iron status and auditory functions in healthy term newborns has not been clearly elucidated among humans. The goal of this pilot study was to determine the relationship between markers of iron status during pregnancy and brainstem auditory function in healthy neonates.
Methods: Pregnant women who gave birth at the Montfort Hospital were recruited to take part in this study (n=6). Within two weeks after birth, their newborn’s hearing function was assessed by wave amplitude, latency and inter-latency from the Auditory Brainstem Response (ABR) test. Markers of iron status, namely hemoglobin (Hb) and mean corpuscular volume (MCV), were collected retrospectively for the first and second trimester from the women’s medical chart.
Results: Overall, no significant relationship was observed between maternal Hb and MCV concentrations and newborns auditory function. Although two significant Spearman correlations were observed (MCV and inter-latency I-V; r=0.87; p=0.005 and Hb and amplitude V; r=0.89; p=0.04), these findings may be due to chance because of multiple testing and the small sample size.
Conclusion: Although iron is a key nutrient involved in the brain and auditory system development, we were not able to demonstrate a relationship between iron status during pregnancy and newborn hearing function. Prospective or intervention studies with a larger sample size and with more specific iron markers (ex. ferritin) are required to confirm these findings.

▼ The
auditory brainstem response (
ABR) is an
electrophysiological measure of hearing commonly used to detect
hearing loss. Indeed, comparisons of
ABR and behavioral thresholds
have indicated that the two measures are, on average, highly
correlated. However, recent research using rats has indicated that
although the
ABR may be correlated with behavioral measures of
hearing, it does not reliably measure the degree of sensorineural
threshold shift caused by exposure to loud sound. Considering these
findings, the purpose of this study was to determine if the
ABR can
reliably estimate the degree of threshold shift caused by a
conductive hearing loss. This was done by measuring the
ABR and
behavioral threshold shifts caused by placing an earplug in the
ears of normal human observers. The results indicated that although
the
ABR was fairly accurate in estimating mean threshold shift for
a group, it did not accurately estimate individual threshold
shifts.

▼ The basic measure of an animal’s hearing is the
behavioral, pure-tone audiogram, which shows an animal’s
sensitivity to pure tones throughout its hearing range. Because
obtaining a behavioral audiogram on an animal can take months, the
tone-evoked
auditory brainstem response (
ABR) is often used instead
to obtain thresholds. Although the tone-evoked
ABR is obtained
quickly and with relative ease, it does not accurately reflect an
animal’s behavioral sensitivity to pure tones. Because several
lines of evidence suggested that using narrow-band noise to evoke
the
ABR might give a more accurate measure,
ABR thresholds evoked
by one-octave noise bands and short-duration tones (tone pips) were
compared in rats to determine which most closely estimated the
animals’ behavioral, pure-tone thresholds. The results indicated
that although the
ABR thresholds evoked by octave-band noise
(noise-evoked
ABR) were a closer match to behavioral thresholds
than those evoked by tone pips (tone-evoked
ABR), absolute
thresholds still did not provide a sufficiently close estimate of
the behavioral audiogram. However, when corrected for the mean
difference between the noise-evoked
ABR and behavioral thresholds,
the noise-evoked
ABR did show the potential for estimating
high-frequency hearing sensitivity. It should be noted, this
finding was a post hoc observation, and requires replication. Three
additional findings of this study were: (1) an improved behavioral
measure of low-frequency hearing in the laboratory rat, (2) the
unexpected finding that damage to the middle ear portion of one ear
resulted in transient increased behavioral thresholds for high
frequencies in the other ear, and (3) signs of age-related,
high-frequency hearing loss that occurred between 14 and 19 months
of age.

▼ Objective: The aim of this study was to compare
cervical and ocular vestibular evoked
myogenic potentials (cVEMP
and oVEMP) in young gender- and age-matched black
African and
Caucasian male and female adults.
Design: A quasi-experimental
between-subjects research design was utilised. This study
was
comparative in nature, thus data was collected in a cross-sectional
manner from two
age- and gender-matched racial groups, namely
black African and Caucasian, and
compared. Furthermore,
interactions of gender and race were also examined in this
research study.
Methods: Sixty healthy age- and gender-matched
participants (30 black African, 30
Caucasian) between the ages of
18 25 years participated in this study. Fifteen males
and fifteen
females, within one year of the age of their racial participant
counterparts, were
included in each racial group. Latencies,
peak-to-peak amplitudes and asymmetry ratios
were analysed for
both groups in these tests. Furthermore,
auditory brainstem
response
(
ABR) and electromyography (EMG) testing were conducted
to investigate whether
possible racial differences in VEMP tests
could be attributed to differences in neural or
muscular
function.
Results: Black African participants demonstrated
significantly shorter latencies of the n23
component of the cVEMP
and the p15 component of the oVEMP, as well as larger peakto-
peak
amplitude of the oVEMP response. Highly significant differences
were found in all
EMG measurements between the two racial groups,
suggesting that these racial VEMP
differences are primarily based
on differences in muscular function between black Africans
and
Caucasians. Significant gender differences were observed in all
tests conducted, with
females predominantly displaying shorter
latencies, while males had larger amplitudes.
Conclusions: Young
black African adults demonstrated significant differences in both
cVEMP and oVEMP
responses, namely shorter latencies and larger
amplitudes, in
comparison to young Caucasian adults. Correlations
with differences in EMG
measurements suggest that these
differences are primarily due to differences in muscular function
as opposed to neural function. Future research is required to
confirm and expand
on these findings.

▼ The Auditory Brainstem Response (ABR) assesses brainstem function. This thesis explores the click and speech ABR in both healthy adults and adults with alcohol dependence syndrome (ADS). Experiment One undertook auditory-cognitive assessment including ABRs, of 60 healthy adults (30 women), aged 18-30 years. For waves III and V of the click ABR, women's responses were earlier than men's by 0.14ms and 0.19ms. For the speech ABR, onset and offset measures were earlier in women by at least 0.43ms. No effect for left vs. right ear was found in either case. Inter-rater reliability was found to be high (ICC2,1 ≥0.89) for the click ABR and good (ICC2,1 ≥0.75) for six of the seven peaks of the speech ABR. A comparison of ABRs to those from an older group of 12 adults aged 31-49 years (six women, matched control group for Experiment Two) found the stimulus to response lag for the speech ABR, was earlier (0.78ms) in the older women but within the expected range. Click and speech ABRs were repeated after 12 weeks and the representation of F0 for women was greater by 4.8 μV at the second recording. Experiment Two assessed the auditory-cognitive profile and ABRs of 16 adults (six women) aged 29-49 years, undergoing a treatment and rehabilitation programme for people with ADS. All participants had hearing thresholds within normal limits, but exhibited deficits in auditory-cognitive profiles compared to matched, healthy adults, including their click and speech ABRs. For the click ABR, men had significant delays in wave III (0.18ms) and wave V (0.22ms). For women there were significant delays for wave I (0.11ms) and wave V (0.22ms). For the speech ABR, men had significant delays in the onset measures of waves V (0.40ms) and A (0.36ms). Women had significant delays in waves V (0.45ms), A (0.48ms) E (0.66ms) and O (0.42ms). Testing was repeated after 12 weeks of abstinence and significant improvements in the click and speech ABR were observed. For men, average click ABR latencies improved for wave III (0.12ms) and wave V (0.22ms) and for women, wave V (0.08ms) improved. Significant improvements were also found for discrete peak and onset measures of the speech ABRs for both men and women. For men, average speech ABR latencies improved for wave A (0.23ms) and the duration of the VA complex (0.15ms). For women there were improvements in wave V (0.10ms), A (0.12ms) and E (0.33ms). These results add to the body of knowledge about the ABR and support its value as a clinical tool. They also provide new information about auditory-cognitive function in adults with ADS, for whom beneficial effects of abstinence are demonstrated. The ABR has a potential role in identifying people most at risk of alcohol related brain damage and in monitoring recovery with abstinence.

▼ Ce travail s’est intéressé au traitement sous cortical de la parole dégradée par le bruit, notamment par la caractérisation première de l’importance de certains traits acoustiques dans la perception de la parole normale. Pour cela, nous avons d’abord participé à la mise au point de la technique électrophysiologique de potentiels évoqués auditifs obtenus en réponse à des sons de parole, technique proche de celle des potentiels évoqués auditifs précoces, mais qui a des exigences propres en matière de traitement du signal et de techniques de recueil, qui nécessitent une adaptation importante de part la nature différente des stimuli français par rapport aux stimuli anglais utilisés par l’équipe de référence américaine. Les différents axes de notre recherche ont, par ailleurs, permis de mettre en évidence l’importance de l’encodage sous cortical de certaines caractéristiques acoustiques telles que l’enveloppe temporelle, le voisement, mettant par là même en évidence un possible effet corticofuge sur l’encodage de celui-ci. Ces différentes expériences nous ont amenés à nous poser la question des conditions idéales de recueil des PEASP, et notamment l’effet de l’intensité sur le recueil de ceux-ci, mettant en évidence une relation non-linéaire entre l’intensité de stimulation, et les caractéristiques des PEAPSP. Si une intensité de 20 dB SL semble nécessaire au recueil d’un PEAPSP, les réponses montrent une variabilité qui reste très grande à l’échelon individuel, ce qui rend l’utilisation de l’outil PEAPSP à visée diagnostique, que ce soit dans les troubles du langage chez l’enfant, ou dans les troubles de l’audition dans le bruit, difficile.
The major purpose of my thesis was the investigation of brainstem structures implications into speech in noise processing, particularly by identifying the impact of acoustic cues on normal speech perception. Firstly, we were involved in the engineering of the speech auditory brainstem responses (SABR) recording system. SABR are similar to brainstem auditory evoked responses to clicks, but require different acquisition and signal processing set-ups, due to the difference between the French and the American stimuli used by the American reference team. The different studies presented here, permitted to emphasize the role of brainstem structures into the subcortical processing of acoustical cues, such as the temporal enveloppe, or the voicing, with a possible evidence of a corticofugal effect on SABR. These experimentations lead us to a more fundamental question on the best conditions required for PEASP collection, in particular, the best stimulation intensity needed. The results of the experiment on intensity effect showed a non linear relation between the stimulation intensity and PEASP characteristics. Even if an intensity of only 20 dB SL seems enough for SABR recording, individual results are still highly variable so that diagnostic application of SABR on, for example, children with language learning problems or subject suffering from speech in noise perception impairment remains…

▼ Auditory Neuropathy Spectrum Disorder (ANSD), a type of hearing loss, is characterized by the presence of otoacoustic emissions and an absent/abnormal
auditory brainstem response (
ABR). This study investigated the potential utility of slow stimulus rate
ABR in ANSD, including whether
ABR morphology at a slow stimulus rate had valuable prognostic features. This retrospective case review comprised 4 children with ANSD. ABRs were recorded using a slow rate stimulus (5.1 CPS) and a faster rate (> 11.1 – 31.1 CPS).
ABR waveform characteristics were compared between the rates and assessed for recognizable morphology. Results indicated that there was no improvement in
ABR waveform morphology in the slow click rate
ABR, suggesting that even when stimulus rates are greatly slowed, neural dys-synchrony persists at the level of the
brainstem. Additionally, neither the slow nor faster click rate
ABR had morphological features which could predict central
auditory pathway maturation or cortical
auditory evoked potentials.

ABR morphology at a slow stimulus rate had valuable prognostic features. This retrospective case review comprised 4 children with ANSD. ABRs were recorded using a slow rate stimulus (5.1 CPS) and a faster rate (> 11.1 – 31.1 CPS).
ABR waveform characteristics were compared between the rates and assessed for recognizable morphology. Results indicated that there was no improvement in
ABR waveform morphology in the slow click rate
ABR, suggesting that even when stimulus rates are greatly slowed, neural dys-synchrony persists at the level of the
brainstem. Additionally, neither the slow nor faster click rate
ABR had morphological features which could predict central
auditory pathway maturation or cortical
auditory evoked potentials.

Lateralization Effects of Brainstem Responses and Middle

▼ Background: Previous human
auditory brainstem
response (
ABR) studies have suggested that the right ear
auditory
network preferentially processes a spectrotemporally complex speech
syllable and the left ear
auditory network preferentially processes
temporally devoid spectral stimuli. Human cortical studies also
suggest lateralization effects to spectral versus temporal stimuli.
However, it remains unclear if the reported
brainstem
lateralization effects may be due to the spectrotemporal content or
the higher order lexical content of the evoking speech stimulus.
Also, the lateralization effects observed at the cortical level in
late evoked
auditory potentials are based upon
responses obtained
well after the stimulus has arrived to the
auditory cortices (~100
ms). Lateralization effects to spectrotemporally complex stimuli
are unknown upon first arrival to the
auditory cortices or in the
auditory middle latency Pa response which occurs approximately 30
ms post-stimulus. Purpose: The purpose of this
study was to gain a better understanding of how the human
auditory
processing system encodes spectrotemporally complex acoustic
stimuli from subcortical levels to first arrival at the bilateral
cortices. Research Design: This study is a
comparative analysis of both
brainstem frequency following
responses (FFRs) and cortical
auditory middle latency
responses
(AMLRs) to spectrotemporally complex speech and spectrally complex
nonspeech stimuli evoked from right and left ear stimulation in
normal hearing adult females. Study Sample:
ABR
and AMLR
responses elicited by a spectrotemporally complex speech
stimulus /da/ and a spectrally complex nonspeech stimulus were
obtained in a group of twenty right-handed normal hearing adult
females. Data Collection and Analysis:
Electrophysiological
brainstem FFRs and AMLRs were recorded using a
40 ms synthesized speech syllable /da/ presented both forwards and
backwards in addition to a 40 ms complex tone. Monaural ipsilateral
FFRs and AMLRs were obtained with insert earphones at an intensity
of 80 dB SPL. Results: There were no significant
differences in the right or left ear evoked FFRs to the complex
tone or the speech stimulus played either forwards or backwards.
However, the left ear AMLRs to the speech syllable played both in
the forwards and backwards mode were significantly earlier than
those obtained from the right ear. Conclusions:
The results from this study do not support previous findings of a
subcortical right ear advantage (REA) for any portion of the
synthetic syllable /da/ and suggest that the subcortical neural
network does not preferentially process short duration
spectrotemporally complex acoustic stimuli differently based upon
the spectral, temporal or lexical content of the stimulus. However,
the AMLR results suggest that the neural mechanisms generating the
AMLR Pa response react earlier to the speech syllable played both
forwards or backwards during left ear stimulation. It may be
deduced that the earlier Pa
responses to left ear…

▼ Determining
auditory functioning in difficult-to-test
populations such as cerebral palsy (CP) remains a challenge in
paediatric audiology. The
auditory brainstem response (
ABR) is
favoured as the procedure to assess
auditory functioning in
difficult-to-test populations such as CP. The CP population,
however, offers unique challenges for the
ABR procedure due to the
presence of involuntary muscular movements that may compromise the
signal-to-noise ratio (SNR) of the
ABR. Conventional
ABR technology
attempts to improve the SNR by the modification of acquisition
parameters e.g. adjusting the low cut filter or implementing
stricter artifact rejection criteria. However, such modifications
may compromise the waveform morphology of the
ABR. Furthermore,
sedation or general anesthesia can also be used to improve the SNR
by reducing excessive muscular movements. The CP population,
however, displays a high risk for developing upper airway
obstruction when being sedated or anesthetized. Thus, the
feasibility and reliability of the conventional
ABR may be
compromised when being employed in the CP population. In recent
years a novel
ABR system, the Vivosonic Integrity (VS)
ABR has
become clinically available. The device incorporates features such
as pre-amplification of the
ABR signal, Kalman filtering and
wireless recording. These features promise to address the
limitations of conventional
ABR technology to obtain a reliable
recording in the midst of excessive myogenic artifact. The aim of
this study was therefore to evaluate the clinical utility of the VS
system when assessing a sample of children with CP without the use
of sedation. The clinical utility of the VS
ABR system was
determined by comparing its success rates, the threshold
correspondence to behavioural pure tone (PT) thresholds and
recording time to a conventional
ABR system when using click and
0.5 kHz TB stimuli. A cross-sectional within-
subject comparison
research design was selected in order to compare thresholds
obtained with different procedures. The experimental part of this
study was represented by the within-
subject control condition where
the VS
ABR system and the conventional
ABR system were
simultaneously conducted in each
subject. This unique setup was
important in the research as equivalent test conditions in terms of
EEG and environmental conditions had to be ensured for both
ABR
systems. 15 CP subjects between the ages of 12 and 18 years were
included in the project. A diagnostic audiological test battery
including immittance, distortion product otoacoustic emissions and
behavioural audiometry was conducted on each
subject prior the
administration of the
ABR procedures. The variability of the
audiological test battery results – between the subjects and when
compared to previous research – emphasized the heterogeneity of the
CP population. Furthermore, more than half of the research sample
(53%; n=15) responded inconsistently to behavioural pure tone (PT)
stimuli. It was suggested that the severity of physical impairments

The physiological mechanisms allowing humans to selectively attend to a single conversation in acoustically adverse situations, such as overlapping conversations or background noise, are poorly understood. In particular, the extent to which goal-directed, top-down processes of auditory attention can modulate the inner ear activity via the auditory efferent system remains unclear. This thesis investigates the relationship between degraded speech and the auditory efferent control of the cochlea. Young, normal-hearing, participants were assessed in a series of three experiments where speech intelligibility was manipulated during Active and Passive listening to: 1) noise vocoded speech; 2) speech in babble noise and 3) speech in speech-shaped noise. A lexical decision task was used in the “Active” listening condition where subjects were instructed to press a button each time they heard a non-word. In the “Passive” listening condition they were instructed to ignore all auditory stimuli and watch a movie. Click-evoked OAEs (CEOAEs) were obtained from the ear contralateral to the speech stimuli, allowing the measurement of cochlear-gain changes. A 64-channel EEG was synchronized with the CEOAE recording system, enabling the simultaneous measurement of cortical speech-onset event-related potentials (ERPs), click-evoked auditory brainstem responses (ABRs) and behavioural responses. Behavioural results showed that accuracy declined as the speech signals were degraded, while ERPs components were enhanced during the Active condition compared to the Passive condition. A decrease in cochlear gain (reduction in CEOAE amplitudes) with increasing task difficulty was observed for noise vocoded speech, but not for speech in babble or speech-shaped noise. Brainstem components showed decreased activity linked to CEOAE suppression. These findings contribute to an integrative view of auditory attention as an adaptive mechanism that recruits cochlear gain control via the auditory efferent system in a manner dependent upon the auditory scene encountered.

▼ A ce jour, six millions de français sont atteints de troubles de l'audition. Face à ce problème de santé publique, des outils performants d'exploration de la fonction auditive sont indispensables. La Speech ABR (Speech Auditory Brainstem Response ou Réponse du tronc cérébral auditif à la parole) est un outil prometteur, comme marqueur électrophysiologique fin de l'encodage neuronal de la parole. Cependant, sa méthodologie reste peu développée, son origine neuronale incertaine et elle n'a jamais été enregistrée chez le malentendant porteur d'aides auditives. Le premier axe de cette thèse porte sur les générateurs neuronaux de la Speech ABR. Le développement d'une méthodologie de recueil topographique de cette réponse jusqu'alors décrite comme strictement sous-corticale, a d'abord suggéré la possibilité d'un générateur cortical. Une étude en stéréo-électroencéphalographie a ensuite confirmé l'existence d'une activité Speech ABR dans les cortex auditifs primaires bilatéraux. Ce résultat apporte un éclairage nouveau sur la représentation des sons de parole par système nerveux auditif. Le second axe concerne l'étude de la Speech ABR chez le malentendant appareillé. Après avoir développé une méthodologie de stimulation acoustique directement au travers des aides auditives, nous avons étudié la plasticité neuronale induite par le port d'aides auditives. Les résultats montrent une amélioration de l'identification des phonèmes amplifiés, liée à une représentation corticale modifiée et à un encodage fréquentiel rééquilibré. Ces toutes premières preuves de plasticité neuronales dès les 4 premiers mois d'utilisation des aides auditives ouvrent de nouveaux espoirs thérapeutiques
To date, six million French are hearing impaired. To address this public health issue, efficient tools for exploration of the hearing function are essentials. Speech ABR (Speech Auditory Brainstem Response) is a promising tool, being a fine electrophysiological marker of the neuronal encoding of speech. Though, its methodology remains underdeveloped, its neural origin is still uncertain, and it has never been recorded in hearing aid users. The first axis of this thesis focuses on the neural generators of Speech ABR. The development of a methodology for recording topographies of this response, up to now described as strictly subcortical, first suggested the possibility of a cortical generator. A stereo-electroencephalography study then confirmed the existence of Speech ABR activity in bilateral primary auditory cortices. This result sheds a new light on the representation of speech sounds within the auditory nervous system. The second axis concerns the study of Speech ABR in hearing aid users. After having developed a methodology of acoustic stimulation directly through hearing aids, we investigated neural plasticity induced by hearing aid use. Results show an improvement in the identification of amplified phonemes, linked to an altered cortical representation and a rebalanced frequency encoding. This very first evidence of neural plasticity as soon as…

▼ After the findings were reported for the Women’s Health Initiative (WHI) study in the past decade, there has been a significant decline in the overall use of hormone replacement therapy (HRT) among women. However, there are still millions of middle-aged, menopausal women in the U.S. who are currently undergoing hormone therapy. Their reasons for continuing treatment include relief of severe menopausal symptoms, aid in the management of osteoporosis and reduction in the risk of colon cancer (Ness et al., 2005). The purpose of the following investigation was to evaluate the impact of HRT on the central and peripheral auditory systems both during and after treatment. Over the course of the study, hormone treatments were administered to female aging CBA/CaJ mice to observe what effects estrogen (E) and progestin (P) have on the peripheral and central auditory systems. Female CBA/CaJ middle age mice were ovariectomized and placed into 4 HRT groups (E, P, E+P and Placebo [Pb]). Hormone treatment lasted 6 months followed by a recovery/washout period of 1 month. During this time, electrophysiology tests such as auditory brainstem responses (ABR) and ABR gap in noise (GIN) were used to measure neural activity for the auditory nerve and brainstem. Distortion product otoacoustic emission (DPOAE) testing was also implemented to assess the functional status of the outer hair cells (OHC) and their ability to amplify sound in the cochlea. After 6 months of treatment, animals treated with E exhibited the least amount of changes in ABR thresholds and ABR GIN amplitudes than any other subject groups. Interestingly, P animals exhibited an abrupt increase in ABR thresholds only 3 months after treatment; however, for ABR GIN amplitude levels a progressive reduction observed throughout the study. E+P and Pb animals showed signs of accelerated age-related hearing loss (ARHL) with significantly elevated ABR thresholds and dwindling ABR GIN amplitude levels. No significant signs of recovery were observed for any of the hormone groups. Therefore, in the present murine investigation, the effects of HRT were long lasting.
To further expand on the results obtained for the electrophysiology tests, molecular biology experiments were performed to evaluate the expression of IGF-1R and FoxO3 in the cochlea during hormone therapy, from both in vitro and in vivo perspectives. Both genes play significant roles in the PI3K/AKT pathway and were specifically chosen because of their role in anti-apoptotic responses and cell survival. It was hypothesized that E attenuates the effects of ARHL via the PI3K/AKT pathway by up-regulating IGF-1R and FoxO3 to counteract the effects of oxidative stress in the aging mammalian cochlea. qPCR experiments were performed with stria vascularis (SV) lateral wall cells extracted from the cochlea of each animal in the hormone groups post-treatment (in vivo) and in SVK-1 cells treated with HRT over various lengths of time (in vitro) to evaluate the expression levels of IGF-1R and FoxO3. In-vivo experiments showed that the…

▼ Depuis quelques années, des recherches décrivent des effets alarmants de l’exposition à des environnements acoustiques artificiels sur les propriétés fonctionnelles des neurones du système auditif. L’objectif de ce projet était de déterminer si une exposition à très long terme à une intensité sonore, qui n’est pas reconnue par les législations pour provoquer des pertes permanentes ou temporaires (80dB SLP 8h/jour), induisait ou pas des changements au niveau des audiogrammes et des propriétés fonctionnelles des neurones du cortex auditif primaire.Des rattes adultes (Sprague Dawley) ont été exposées entre 3 mois à 18 mois (selon les groupes) à un milieu acoustique mimant les environnements sonores quotidiens de la majorité de la population et dont les effets n’ont jamais été étudiés sur de telles durées. L’originalité de ce projet réside dans l’analyse des effets à tous les niveaux du système auditif depuis le niveau périphérique (ABRs) jusqu’au niveau central (électrophysiologie corticale) ainsi que les conséquences possibles au niveau comportemental. Une tâche d’apprentissage perceptif inédite a été mise au point afin d’évaluer les effets de l’exposition. Au cours du vieillissement, nos données montrent une baisse des performances comportementales, une atteinte progressive des seuils ABRs et des atteintes de certains paramètres des réponses neuronales comme (i) la latence, (ii) la durée, (iii) la détection de silence dans une vocalisation, (iv) le suivit d’une modulation d’amplitude, (v) la reproductibilité des réponses à une vocalisation. Le principal effet de l’exposition à un environnement bruité est l’apparition d’un TTS après 6 à 12 mois d’exposition (qui disparait complètement en 3 semaines), sans que cela ait, de façon très surprenante, la moindre conséquence notable sur les seuils ABRs, l’activité évoquée corticale, ou les performances de discrimination des animaux. Ces résultats nous incitent à la prudence sur la généralisation des conclusions à tirer des expositions à des environnements bruités artificiels.
Over the last few years, studies have described alarming effects of exposure to artificial acoustic environments on the functional properties of neurons in the auditory system. The aim of this project was to determine if long-lasting exposure at a sound intensity which is not recognized by the legislation to cause permanent or temporary hearing loss (80 dB SLP 8h/ day) induced, or not, changes in the audiograms and functional properties of neurons in theprimary auditory cortex. Adult female rats (Sprague Dawley) were exposed over 3 to 18 months (depending on the group) to an acoustic environment mimicking daily sound environments surrounding a large part of the population, and whose effects have never been studied on such durations. The originality of this project lies in analyzing the effects at alllevels of the auditory system from peripheral (via ABRs) to central levels (cortical electrophysiology) and also the possible consequences at the behavioral level. A new perceptual learning task has been…

▼ In mammals, the basic computations required for azimuthal sound localization are performed by a group of auditory brainstem nuclei known as the superior olivary complex (SOC). The lateral superior olive (LSO), in the SOC, aids in sound localization by computing intensity differences between sounds arriving at the two ears. It does this by comparing excitatory input from the ipsilateral anteroventral cochlear nucleus (AVCN) with inhibitory input from the ipsilateral medial nucleus of the trapezoid body (MNTB), which is driven by the contralateral AVCN. In order for sounds to be accurately localized, the AVCN-LSO and MNTB-LSO projections must be aligned with each other in a frequency-dependent manner. Rough alignment occurs over the course of development, but a significant amount of circuit refinement is required to achieve adult-like precision. Two types of refinement occur in these pathways: 1) physiological, or functional refinement; and 2) anatomical refinement. Little is known about the latter type of refinement in the AVCN-LSO pathway.
In order to study this, I conducted a variety of experiments all aimed at anterogradely labeling a small number of cells projecting from the AVCN to the LSO in juvenile rats. I experimented with several approaches in order to develop the technique of ex vivo, sparse axon labeling in this area of the brain. I show the optimal technique developed after testing various tracers, application methods, and incubation times, among others. This optimized technique can now be used in a future experiment that will uncover and describe anatomical refinement in the AVCN-LSO pathway of the auditory brainstem.

▼ Several adaptive filters were investigated to enhance speech auditory brainstem responses (speech ABR). The objective was to shorten the long recording time currently needed by the standard coherent averaging method to obtain acceptable performance, which has limited the clinical adoption of speech ABR. Five algorithms were implemented: Wiener Filter (WF), Steepest Descent (SD), Adaptive Noise Cancellation (ANC) based on Least-Mean-Square error (LMS) and normalized LMS error (nLMS), and a multi-adaptive cascade combination of SD and LMS. The performance of the adaptive filters was assessed on speech ABR data gathered from several subjects and compared with coherent averaging using the overall Signal-to-Noise Ratio (SNR), the local SNR around the fundamental frequency and the first formant, and Mean-Square-Error (MSE) in the time and frequency domains. The adaptive filters could reduce the time needed, by at least one order of magnitude, for obtaining comparable signal quality as that obtained with coherent averaging.

▼ Screening for retrocochlear involvement is a significant task in the modern ENT Clinic. Although magnetic resonance imaging is considered the definitive investigation for diagnosis of such disorders, the auditory brainstem response (ABR) remains a valuable and effective screening tool, for auditory or vestibular nerve dysfunction. Its sensitivity for lesions of the lower brainstem, such as acoustic neuromas being of special concern to the otolaryngologist, is well established, but unfortunately cochlear hearing loss is often a confounding factor in the evaluation of ABR results. The aim of this study was to analyse the effects of various types of cochlear loss on the results of the ABR test in a large clinical group. This analysis should provide information which will allow better targeting and interpretation of the ABR in retrocochlear assessment, when concurrently cochlear hearing loss occurs.
Η διάγνωση της οπισθοκοχλιακής βλάβης αποτελεί σημαντικό έργο στην Ωτορινολαρυγγολογική Κλινική σήμερα. Παρότι η μαγνητική τομογραφία θεωρείται η εξέταση εκλογής για την διάγνωση τέτοιας βλάβης, τα ακουστικά προκλητά δυναμικά (ΑΠΔ) εξακολουθούν να αποτελούν ένα πολύτιμο και αποτελεσματικό διαγνωστικό εργαλείο, για την διάγνωση ακουστικής ή αιθουσαίας δυσλειτουργίας. Η μεγάλη ευαισθησία της μεθόδου για την εντόπιση βλαβών του κατωτέρου εγκεφαλικού στελέχους, όπως είναι τα ακουστικά νευρινώματα, τα οποία απασχολούν ιδιαίτερα τον ωτορινολαρυγγολόγο, είναι ομόφωνα αποδεκτή, αλλά δυστυχώς η κοχλιακή βαρηκοϊα αποτελεί συχνά έναν παράγοντα που επιφέρει σύγχιση στην αξιολόγηση των αποτελεσμάτων των ΑΠΔ. O σκοπός της μελέτης αυτής ήταν να αναλύσουμε την επίδραση των διαφόρων τύπων κοχλιακής βαρηκοϊας στα αποτελέσματα των ΑΠΔ, σε μια μεγάλη ομάδα ασθενών. Η ανάλυση αυτή πιθανόν να βοηθήσει στην καλύτερη επιλογή παραμέτρων και ερμηνεία των ΑΠΔ σε περιπτώσεις οπισθοκοχλιακής βλάβης, όταν συνυπάρχει κοχλιακή βαρηκοία.

▼ Background Congenital hearing impairment is proved to be one of the most frequently occurring sensory birth defects. NICU graduates are considered to be of higher risk for hearing impairment, either auditory neuropathy or hearing loss. The severity of hearing impairment during the early life critical periods of speech development determines the acquisition of fluent lingual ability thus it is crucial that any underlying hearing disorder is diagnosed and treated as early as possible.In this study, we focus on the presence of audiological risk factors and try to clarify their correlation to the development of congenital hearing loss, including ANSD, in the population of newborns hospitalized in the NICU of our tertiary hospital. Materials and MethodsIn the present prospective cohort study, 453 neonates admitted to the NICU, between 2012 and 2016, for more than 24 hours with one or multiple risk factors were analyzed. All newborns were subjected to hearing screening test at least 48 hours after birth, by the use of automated ABRs (a-ABRs) in combination with Transiently Evoked Otoacoustic Emissions (TEOAEs). Newborns who failed the initial test were re-examined before their first month of age and if they still did not manage to pass the screening, they were referred to the audiology department for full hearing evaluation.ResultsOut of 453 neonates, 71 failed the initial hearing evaluation. Only 49 of them presented in the re-examination, resulting eventually in 8 neonates (1.8%) failing both a-ABRs and TEOAEs and being diagnosed with possible sensorineural hearing loss (HL), while 8 neonates (1.8%) passed TEOAEs but failed a-ABRs and were diagnosed with possible auditory neuropathy spectrum disease (ANSD). Ototoxic medication, prematurity, assisted ventilation, low birth weight and hyperbilirubinemia were the most frequently appeared of the 13 individual risk factors investigated. The majority of newborns (48%) presented with two risk factors. Low birth weight was proved to be of statistical significance regarding possible HL (p=0.002) while craniofacial deformities and TORCH infections depicted statistically significant attribution (p=0.03 και p=0.05 respectively) to the occurrence of possible hearing impairment, either HL or ANSD.ConclusionsABRs and OAEs remain the cornerstones of any universal hearing screening program in neonatal intensive care units as a significant number of children may have auditory neuropathy. Constant re-evaluation of risk factors and their relation to the development of hearing impairment is needed as they change through time. An efficient secretariat system is needed to reduce the number of lost to follow-up neonates.

▼ Purpose: The objectives of this dissertation are to: (1) evaluate the influence of aging on the sub-cortical (
brainstem) differentiation of voiced stop consonants (i.e. /b-d-g/); (2) determine whether potential aging deficits at the
brainstem level influence behavioral identification of the /b-d-g/ stimuli, (3) investigate whether spectral shaping diminishes any aging impairments at the
brainstem level; and (4) if so, whether minimizing these deficits improves the behavioral identification of the speech stimuli.
Subjects: Behavioral and electrophysiological
responses were collected from 11 older adults (> 50 years old) with near-normal to normal hearing and were compared to those of 16 normal-hearing younger adults (control group).
Stimuli and Methods: Speech- evoked
auditory brainstem responses (Speech-ABRs) were recorded for three 100-ms long /b-d-g/ consonant-vowel exemplars in unshaped and shaped conditions, for a total of six stimuli. Frequency-dependent spectral-shaping enhanced the second formant (F2) transition relative to the rest of the stimulus, such that it reduced gain for low frequencies; and increased gain for mid and high frequencies, the frequency region of the F2 transition in the /b-d-g/ syllables. Behavioral identification of 15-step perceptual unshaped and shaped /b-d-g/ continua was assessed by generating psychometric functions in order to quantify stimuli perception. Speech
ABR peak amplitudes and latencies and stop consonant differentiation scores were measured for 6 stimuli (3 unshaped stimuli and 3 shaped stimuli).
Summary of Findings: Older adults exhibited more robust categorical perception, and subtle sub-cortical deficits when compared to younger adults. Individual data showed fewer expected latency patterns for the /b-d-g/ speech-ABRs in older adults as opposed to younger adults, especially for major peaks. Spectral shaping improved the stop consonant differentiation score for major peaks in older adults, such that it moved older adults in the direction of the younger adults’
responses.
Conclusion: Sub-cortical impairments at least those measured in this study do not seem to influence the behavioral differentiation of stop consonants in older adults. On the other hand, cue enhancement by spectral shaping seems to overcome some of the deficits noted at the electrophysiological level. However, due to a possible ceiling effect, improvements to the originally robust perception of older adults, at the behavioral level were not found.
Significance: Aging seems to reduce the sub-cortical responsiveness to dynamic spectral cues without distorting the spectral coding as evident by the “reparable” age-related changes seen at the electrophysiological level. Cue enhancement appears to increase the neural responsiveness of aged but intact neurons, yielding a better sub-cortical differentiation of stop consonants.

▼ There is much evidence supporting the idea that pelagic larvae of coral reef fishes are active participants in their dispersal and return to a reef, however, the mechanisms used to navigate are still uncertain. It has been proposed that sensory cues, such as hearing, play a role. Sound is a potentially important cue for organisms in marine environments, especially in noisy environments like coral reefs. Sensory organs, including otolithic organs, of most coral reef fish form within the first few days of life. The auditory brainstem response (ABR) technique was used to measure hearing on a wide size range of sergeant majors (Abudefduf saxatilis). Complete audiograms were measured for 32 fish ranging in size from 11-121 mm. Significant effects of standard length on hearing thresholds at 100 and 200 Hz were detected. At these lower frequencies, thresholds increased with an increase in size. All fish were most sensitive to the lower frequencies (100-400 Hz). The frequency range that fish could detect sounds was dependent upon the size of the fish; the larger fish (>50mm) were more likely to respond to higher frequencies (1000-1600 Hz). A. saxatilis have poor hearing sensitivity in comparison to audiograms of other hearing generalists including other species of Pomacentrids. Due to the high hearing thresholds found in this study in comparison to recorded ambient reef noise, it is unlikely that sound plays a significant role in the navigation of the pelagic larvae of sergeant majors to the return of the reef from large distances.

▼ Objective: The air conduction click is currently the most widespread stimulus used to estimate the pure tone audiogram as part of auditory brainstem response (ABR) testing. The click is characterized by its broad spectral content and rapid onset, which may not make it the best choice for frequency specificity. An alternative stimulus is a short duration tone burst stimuli with notched noise masking. When obtaining an ABR using standard unmasked tone bursts, the brief stimulus onset may cause spectral splatter producing response contributions from unwanted regions of the cochlea; thus reducing the frequency specificity of the ABR. Notched noise masking used in conjunction with the tone burst ABR, limits the evoked response to those frequencies within the notch, thereby reducing the likelihood of spectral splatter and increasing frequency specificity. The presence of a sloping sensory hearing impairment creates additional difficulties for achieving frequency specificity because of the likelihood that lower frequency cochlea regions, with less sensory damage, will contribute to the evoked response. It is theorized that notched noise masking will reduce the neural contributions from regions of the cochlear outside those within the notch, resulting in more frequency specific results than those achieved with a standard unmasked tone burst stimulus. The present study was designed to investigate the differences in Wave V latency between the notched noise ABR and the standard unmasked tone burst ABR as a measure of frequency specificity.
Design: Twenty-five participants with normal hearing in at least one ear and 16 participants with bilateral SNHL participated in this investigation. Each participant was given an audiological evaluation, a click ABR screening to determine neural synchrony, a standard tone burst ABR and a notched noise tone burst ABR.
Results: An Analysis of Variance (ANOVA) failed to reveal any significant Wave V latency differences between the ABRs obtained with unmasked tone bursts versus ABRs obtained with a notched noise tone burst.
Conclusion: The results of this study do not support the use of notched noise tone bursts for improved ABR frequency specificity. This finding is contrary to previously reported results (Stapells & Picton, 1981), which indicated improved frequency specificity when obtaining a tone burst ABR in notched noise versus a standard unmasked tone burst ABR.

▼ Pregnant adolescents are at risk of anemia and iron deficiency (ID). Iron stores may be compromised in newborns born to women with ID, which is of concern given the importance of neonatal iron acquisition for neurodevelopment. This study was undertaken in 255 pregnant adolescents ([LESS-THAN OR EQUAL TO] 18 y) receiving prenatal care at the Rochester Adolescent Maternity Program (2006 - 2012). We characterized maternal dietary intake, prenatal supplement use; assessed maternal and neonatal iron status; and examined the impact of neonatal iron endowment on neurophysiological function at birth. Dietary intakes of iron, magnesium, calcium, vitamins D and E did not meet the EAR in more than 70% of teens surveyed, with calcium and magnesium being the nutrients with the greatest dietary deficits. Approximately half of the adolescents selfreported daily use of prenatal supplements, however the additional supplement contribution was insufficient to bridge the dietary deficit for the EAR for magnesium and calcium. From ~26 weeks gestation to delivery, the prevalence of maternal anemia (8.6% to 19%) and ID (sTfR > 8.5 mg/L; 7% to 14%) increased significantly. Elevated concentrations of ferritin and hepcidin were observed at delivery compared to mid-gestation, due to inflammation. Maternal EPO concentrations were significantly associated with indicators of maternal iron insufficiency and with low maternal hemoglobin concentration across pregnancy, and one benefit to this indicator was that EPO was not significantly associated with inflammation across gestation. Of concern, fully 1/4 of the newborns (n=193) were anemic or had low iron stores, respectively at birth. Of interest, cord ferritin did not significantly increase with gestational age across the final 6 weeks of pregnancy (37 - 42 weeks of gestation). Maternal iron stores impacted neonatal iron stores as neonates born to mothers with ferritin < 12 [MICRO SIGN]g/L had significantly lower ferritin compared to their counterparts. These findings speak to the need to examine the efficacy and optimal timing of maternal iron supplementation during pregnancy. No consistent relationships were evident between lower neonatal iron status and longer
ABR peak latencies. Additional methods or functional approaches may be needed to fully capture the impact of neonatal iron status on neurodevelopment and other health outcomes.

▼ Cochlear implants provide hearing to people who are deaf, by electrically stimulating the auditory nerve. Children with a single cochlear implant suffer deficiencies inherent to unilateral hearing, including inability to locate sounds. A second cochlear implant may improve sound localization, which normally requires interpretation of differences in sound intensity and time of arrival between two ears. Currently, it is unknown whether these cues are available to children who were provided with a second cochlear implant after a period of using one implant alone. We asked whether such children could interpret inter-implant level and timing cues. Results indicated that children using two cochlear implants detected level cues but had difficulty interpreting timing cues. Further, children rarely reported that sounds were perceived to come from the middle. Children receiving bilateral cochlear implants sequentially do not process bilateral auditory cues normally but can use inter-implant level cues to make judgments about where sound is coming from.

▼ Objectives: This thesis describes three studies investigating the consistency and reliability of ABR testing procedures, the extent of inter-and intra-rater variability and performance, the impact of additional case information on ABR testing results.
Methods: The participants for all studies were audiologists who conduct ABR testing. Study 1 consisted of a 69-item survey regarding ABR testing protocols that was completed online. In studies 2 and 3, a test set of infant ABR traces was obtained from a large public peadiatric audiology clinic in Sydney, Australia. In Study 2, 61 audiologists estimated hearing threshold for 15 ABR cases that were each presented twice in order to estimate inter and intra-reader variability. In study 3, 14 audiologists were asked to estimate the hearing threshold for 16 infants twice in two sessions at least 5 months apart; with and without provision of standard clinical information.
Results: Audiologists vary in how they conduct ABR testing and there are differences in the training period audiologists undertake before starting ABR testing. Audiologists show good levels of agreement when assessing repeated ABR traces, however, optimum performance was not achieved. No significant differences were found for sensitivity, specificity or accuracy when clinical history information was provided compared to when it was not provided.
Conclusions: There is a need for greater emphasis on the importance of following evidence-based guidelines for ABR testing whenever it is possible. Audiologists’ experience and ABR training periods significantly predicts accuracy of ABR reading. Good levels of agreement were found between and within audiologists. ABR traces are interpreted with the same accuracy regardless of whether patients ‘history information is available or not. The data provided should contribute to an improvement in the service of infants hearing diagnostics and help reduce audiologists’ variability.

▼ This study evaluated auditory function in patients with chronic renal failure. The experimental group included 31 patients with end-stage renal failure on chronic hemodialysis. The control group consisted of 31 healthy volunteers. The patients were examined prior to and following a session of hemodialysis. Measurements included pure tone audiometry, tympanometry and acoustic reflex measurements, Auditory Brainstem Responses (ABR), and blood chemistry parameters. Controls underwent the same test battery, with the exception of biochemical and hematological assessment. A comparison between experimental group before hemodialysis and controls shows that all ABR measures were significantly prolonged in the experimental group, with the exception of interpeak latency I-III. A comparison between controls and the experimental group following hemodialysis, indicated that wave V absolute latency and interpeak latencies III-V and I-V were significantly prolonged in the slow repetition rate[10hz] . In the fast repetition rate [60hz] , absolute latencies of waves I and V and III-V interpeak latencies were prolonged in the experimental group. Comparison of ABR recordings prior to and following hemodialysis showed a significant improvement in absolute latency of wave V after hemodialysis. This study showed that neural conduction along the auditory pathway is delayed in patients with CRF as compared to healthy subjects. Dialysis sessions improve overall neural auditory function. However, patients with CRF show delayed conduction even after a session of hemodialysis.

▼ Objective: This study aimed to systematically review
and analyse the available peer-reviewed literature reporting on the
results of distortion product otoacoustic emissions (DPOAEs),
transient evoked otoacoustic emissions (TEOAEs) and click
auditory
brainstem responses (c-ABRs) in adults with type 1 and type 2
diabetes mellitus (T1DM and T2DM).
Method: A comprehensive
literature search was conducted across three electronic databases
to identify English; peer-reviewed articles that included results
of OAEs (DPOAEs and TEOAEs) and c-
ABR tests in adult subjects with
DM. Articles were selected according to predetermined selection
criteria and critically reviewed independently by two researchers.
Results: 15 studies met the inclusion criteria for the systematic
review while nine articles qualified for inclusion in the
meta-analysis. DPOAE studies reported significantly reduced
amplitudes with only one study reporting larger amplitudes.
Abnormal TEOAEs were reported in all TEOAE studies, although these
abnormalities were not always significant. Significantly delayed
c-ABRs were reported in all
ABR studies. Analysis of c-
ABR mean
wave latencies identified longer latencies for DM subjects,
particularly for wave III and V, as well as for IPL I-III and I-V.
Conclusions: Subjects with T1DM and T2DM may present with clinical
or subclinical impairment of the cochlear outer hair cells and both
the peripheral and central
auditory pathway.
Advisors/Committee Members: Vinck, Bart M. (advisor), Heinze, Barbara M. (coadvisor).

▼ IN THIS STUDY AUDITORY BRAINSTEM RESPONSES (A.B.R.) WERE RECORDED FROM AN EXPERIMENTAL GROUP OF 62 PATIENTS WITH HEARING LOSS DUE TO OTOSCLEROSIS. THE RESPONSES FROM THESE PATIENTS WERE ANALYZED IN TERMS OF WAVEFORM LATENCIES AND INTERWAVE LATENCIES FOR THE WAVES I, III, V. COMPARISONS WERE MADE TO A CONTROL GROUP OF 21 NORMAL LISTENERS. LATENCIES OF WAVES I, III AND V ARE DEMONSTRATED TO PROLONGED IN COMPARISON TO NORMAL VALUES, THOUGH INTERWAVE LATENCIES I-V, I-III AND III-V ARE FOUND TO BE WITHIN NORMAL LIMITS. THE INCREASED WAVE III LATENCY SEEMS TO BE THE MOST SENSITIVE COMPONENT TO THE PRESENCE OF OTOSCLEROSIS. B.E.R.A. CAN BE A VALUABLE TOOL FOR DETECTING THE PRESENCE OF CONDUCTIVE HEARING IMPROVEMENT DUE TO OTOSCLEROSIS AND PERHAPS AS AN ASSESSMENT OF THE DEGREE OF HEARING LOSS.

▼ Psychophysical detection of silent gaps embedded in ongoing steady sounds is commonly used to measure temporal resolution in hearing tests. Long latency
auditory responses to such gaps in a noise signal are routinely investigated as electrophysiological measures of temporal resolution. This study was conducted to investigate the characteristics of early transient
responses (
Auditory Brainstem and Middle Latency) as well as
Auditory Steady State
Responses to such stimuli. Young subjects were monaurally stimulated by three different duration (12ms, 9ms, 6ms) of silence gaps in a white noise. All stimuli in this study were presented with 40 Hz stimulation rate in isochronic or jittered sequences. Quasi ASSRs were deconvolved using the CLAD (Continuous Loop Averaging Deconvolution) algorithm to obtain early transient
responses to individual gaps (Delgado & Ozdamar, 2004).
Responses to conventional clicks were also recorded. All subjects evoked identifiable early transient
responses characterized by two positive and three negative peaks (Ng1,Pg1, Ng2,Pg2,Ng3). Peaks were about 25 ms apart and the first positive peak Pg1 was the most prominent. Results suggest that early
responses to gaps in noise are composite
ABR and MLR
responses generated by noise onsets and offsets. Amplitudes and latencies of early transient
responses and ASSR were affected by gap duration.
