▼ Background: Prior studies have found that continuous theta burst stimulation (cTBS) targeting the left dlPFC results in reliable increases in consumption of calorie-dense food items. However, it is not known to what extent such effects are modified by cues in the immediate eating environment. Tempting environments (i.e., those saturated with appetitive eating cues) may lead to more reliance on cognitive control networks involving the dlPFC, thereby enhancing cTBS effects on indulgent eating. Objective/Hypothesis: The objective was to examine the extent to which cTBS effects on indulgent eating would be modified by contextual cues. It was hypothesized that cTBS effects would be stronger in the presence of facilitating cues. Methods: Using a single-blinded between-subjects factorial design, 107 TMS-naïve adults were randomly assigned to one of four conditions: 1) active cTBS + facilitating cues, 2) sham cTBS + facilitating cues, 3) active cTBS + inhibiting cues, 4) sham cTBS + inhibiting cues. Following stimulation participants completed a flanker paradigm and a taste test during which quantity consumed was assessed surreptitiously. Results: Findings revealed a significant interaction between stimulation and cue type (F(1,102)=6.235, p=.014), such that cTBS resulted in increased food consumption (compared to sham) in the presence of the facilitating cue but not in the presence of the inhibiting cue. Moderated mediational analyses showed selective mediation of cTBS effects on consumption through cTBS attenuation of flanker interference scores. Conclusions: The effects of cTBS on indulgent eating are strengthened in the presence of facilitating cues. Methodologically speaking, facilitating cues may be a functional prerequisite for exploring cTBS effects on eating in the laboratory. Substantively, the findings also suggest that facilitating cues in the eating environment may amplify counter-intentional food indulgence in everyday life via cognitive control failure.

▼ Background and purpose: Even though there is much information and research on neuroplasticity, many questions remain unanswered about how the brain changes and recovers after a stroke. Transcranial magnetic stimulation (TMS) has been used as the primary method of direct stimulation to assess change especially in the primary motor cortex because it allows for study of the specific excitatory and inhibitory mechanisms. The purpose of this study was to investigate and identify differences in TMS-induced intracortical inhibition and facilitation when comparing survivors of stroke to individuals unaffected by stroke. Methods: Fourteen subjects who had experienced a stroke and 19 non-stroke subjects were investigated using single and paired-pulse TMS. TMS was applied over the affected hemisphere for subjects with stroke and over the dominant hemisphere of the non-stroke subjects. Resting motor threshold (MT) was established. Forty motor evoked potentials (MEPs) were collected from the first dorsal interosseus muscle, using surface electrodes, for each subject. These were subdivided into 10 trials of single-pulse conditioning stimulus, 10 trials of single-pulse test stimulus (TS), 10 paired-pulse intracortical facilitation (ICF), 10 paired-pulse intracortical inhibition (ICI); the order of stimulation condition for the 40 trials was randomized. Results: The stroke group exhibited significantly higher MT and significantly lower motor evoked potential amplitudes for TS, ICF, and ICI specific trials compared to the group without stroke. Finally, the ratio of ICF to ICI was found to be significantly lower in the stroke group, indicating less facilitation. Conclusion: Overall the affected hemispheres of the participants surviving stroke were found to be significantly less excitable than the dominant hemispheres of the non-stroke participants. These findings and the usefulness of TMS to directly access and assess differences in the brain's baseline excitability following stroke will hopefully add to existing knowledge that informs therapeutic interventions aimed at increasing post-stroke performance in daily activities.

▼ Background: Previous research has found links between olfactory deficits and depression. Olfactory ability is restored with successful treatment with antidepressant medication. Electroconvulsive therapy (ECT) and repetitive transcranial magnetic stimulation (rTMS) are two effective treatments for depression. It is not known whether these somatic treatments may, similarly to pharmacotherapy, restore olfactory sensitivity and identification ability in individuals with depression. Objectives: The objective of the present study was to determine whether treatment with ECT or rTMS is associated with improvement in olfactory sensitivity or identification in individuals with depression. Methods: Six patients receiving ECT and three patients receiving rTMS completed the study. Before beginning treatment and 20-30 days after their first treatment, patients were assessed using the Smell Threshold Test (STT), Smell Identification Test (SIT), Hamilton Depression Rating Scale (HDRS), Beck Depression Inventory (BDI), and Snaith-Hamilton Pleasure Scale (SHPS). The control group consisted of nine matched healthy participants. Results: There was no significant difference between the ECT, rTMS, and control groups for olfactory sensitivity either before or after treatment. At both testing visits, the rTMS group performed significantly worse on olfactory identification compared to control, while the ECT group performed comparably to control. Olfactory identification ability was significantly correlated with HDRS score at baseline but not after treatment. Olfactory performance was not correlated with BDI or SHPS score. Conclusions: The results of this pilot study suggest that individuals with depression may not have decreased olfactory sensitivity ability compared to healthy controls. However, in those who do exhibit poor olfactory identification, rTMS may be effective in restoring sense of smell. Further research is needed to determine whether olfactory deficits are caused by depressive symptoms, and whether ECT may also restore olfaction in individuals who have olfactory deficits. Determining the links between olfaction and depression may be important for promoting the early diagnosis and treatment of depression, and for improving quality of life and everyday functioning.

▼ This thesis investigated whether acute experimental pain interacts with motor learning acquisition to create adaptive and maladaptive changes in neural function. The first study consisted of two experiments where we determined the interactive effects of acute pain versus control (Experiment 1) and local versus remote acute pain (Experiment 2) on motor learning and sensorimotor processing and provided supportive evidence for early somatosensory evoked potential (SEP) peaks as markers for sensorimotor integration (SMI) and acute pain. Motor performance was better in the presence of pain pre-motor learning and motor learning retention improved in the presence of local pain. A limitation of this first study was that performance saturation occurred and therefore we used a more complex tracing task for the subsequent studies. Our second SEP study The interactive effect of acute pain and motor learning acquisition on sensorimotor integration and motor learning outcomes provides corroboration for the enhancement of motor learning while in acute pain. In addition, the changes in the amplitudes of SEP peaks suggests that SEP peak alterations reflect neurophysiological alterations accompanying both motor learning acquisition and mild acute pain. Improved motor learning acquisition during acute pain may be the result of increased attention or increased arousal, and therefore we concluded that it was important to compare the effects of local versus remote versus contralateral acute pain in conjunction with a complex motor learning task which was the focus of the third study. Our third study found that motor learning occurred in the presence of mild acute pain and there were no significant differences in motor learning acquisition or retention between three groups that had capsaicin applied at different locations. We hypothesized that improved motor learning acquisition during acute pain may have been caused through increased arousal. For the fourth study we explored the effect of acute pain on neuroplasticity of the motor cortex (MI) by using input-output curves elicited via transcranial magnetic stimulation (TMS). The acute pain in this study was shown to negate the increase in slope that was observed for the control group despite having a positive impact on motor learning acquisition.

▼ Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation technique that can modulate brain activity through a time-varying magnetic field which induces an electric field in the brain. TMS has been used extensively in research and clinical applications because of its ability to non-surgically deliver suprathreshold stimulation to the brain in a safe manner. Despite the popularity of TMS, there are still major gaps in our understanding of how TMS modulates brain activity on a fundamental neuroscience level. Therefore, the TMS mechanism of action is still under investigation. Improved stimulation technology and computational tools have promise for bridging this gap in our understanding. In my dissertation, I developed new methodologies and computational models that advance the current state-of-the-art in TMS and can assist researchers in their future investigations. First, I describe a closed-loop TMS system that can deliver the stimulation based on the instantaneous brain state. This allows researchers to investigate the role of the intrinsic neural activity on the brain’s responsiveness to TMS. To further provide insights into how TMS modulates brain activity at a large brain-scale and the neuronal level, I developed a multi-scale modeling paradigm. Computational simulations have been used extensively to estimate electric fields induced in the brain by TMS, however, their results still need to be validated. To this end, in the second study here, I utilize analytical solutions to evaluate these numerical simulations. After confirming the accuracy of the electric field models, I incorporated multi-scale modeling to further investigate how the externally induced electric fields alter the behavior of neurons and their subcellular activity. The subcellular modeling of neurons allows researchers to study the lasting effects of TMS in neurons in a sophisticated multi-scale model for the first time. In summary, the tools developed in my PhD can facilitate answering long-lasting questions about the TMS mechanism of action. This, in turn, will enable developing more effective TMS protocols/equipment which can lead to improved clinical outcomes in the treatment of psychiatric and neurological disorders with TMS.

▼ Repetitive transcranial magnetic stimulation (rTMS) performed at a low frequency has been found to have an inhibitory effect on cortical function, which may result in behavioural consequences. Accordingly, rTMS may provide a valid model of focal cortical lesions, such as stroke, in healthy individuals. rTMS has been further proposed as a tool to inhibit high levels of cortical activity in individuals with aphasia in right hemisphere (RH) language homologues following a stroke that damages primary language regions. It is thought that while RH activity is compensatory during the early stages of recovery from stroke, it is maladaptive in terms of long-term recovery. RH activity has also been reported in healthy, low-proficiency bilinguals during second language (L2) production; thus, it has been proposed that RH activity may be better classified as reflecting effortful language production. Furthermore, given similarities in RH activity during language production in low-proficiency bilinguals and aphasics, non-disabled controls learning an L2 may provide a useful analogue to study aphasia. The research presented in this dissertation examines learning of Spanish as an L2 in unilingual, English speaking adults in an attempt to understand which brain regions are associated with L2 acquisition, and the role that the RH plays in language functioning. Results of this project indicate that adults were able to learn novel Spanish vocabulary through a computer-based language-training program, but that learning was partially dependent on age and information processing capabilities. Unlike previous research that has demonstrated a more extensive network for L2 production, including regions of the RH, we found a less extensive network for Spanish than for English, although English language production was associated with RH activity. Furthermore, inhibitory rTMS produced no effects on lexical retrieval in either English or Spanish, indicating that the virtual lesion induced by TMS is not sufficient to mimic an aphasic stroke. Overall, our results indicate that while the RH does play an important role in language production, that role may differ between healthy and aphasic individuals. Also, neither L2 acquisition nor virtually induced lesions via TMS appear to provide an ideal model of post-stroke aphasia.

▼ Visual motion prediction is essential for making key judgements about objects in the environment. These judgements are typically investigated using a time-to-contact (TTC) task, in which an object travels along a straight trajectory and disappears behind an occluder. Participants make a response coinciding with the moment the object would have contacted a visual landmark. The assumption is that the motion continues behind the occluder. This task is used to measure how we perceive and predict the arrival-time of objects. The addition of sound to TTC tasks generally enhances visual judgements. One characteristic which may affect how sound influences visual motion judgements is pitch. A rising pitch is associated with speeded motion and a falling pitch with slowed motion. Pitch change could therefore lead to biases in visual motion judgements; however, this has not yet been investigated. Furthermore, TTC tasks can utilise horizontal or vertical motion. In vertical motion, an additional variable that may be critical for TTC estimations is gravity. It is postulated that humans possess an internal model of gravity that allows us to make accurate predictions for downward motion. This model assumes faster downward than upward motion. However, this model can be wrongfully applied in constant speed tasks, producing faster speed estimations for downward stimuli when there is no acceleration. Therefore, vertical motion could lead to additional biases in visual motion judgements. This thesis investigated whether pitch and gravity could affect the imagined speed of an object under occlusion. Specifically, a rising pitch was hypothesised to produce speeded predicted motion and falling pitch, slowed predicted motion. I investigated the influence of pitch change in vertical and horizontal planes. I also investigated two different aspects of pitch change, since dynamic pitch is a novel addition to TTC paradigms. Experiment 1A explored gradual pitch change and Experiment 1B used sudden pitch change. The hypothesised pitch effects were observed for a gradual, but not a sudden pitch change. However, a gravity effect was observed across both Experiments 1A and 1B, suggesting the presence of sound does not moderate this effect. I also examined the cortical substrates of the audio-visual TTC task components by using transcranial magnetic stimulation (TMS) in Experiment 2. The superior temporal sulcus (STS) was targeted in this experiment, as it has been implicated in audio-visual integration. TMS causes neuronal inhibition, and as such, can be used to determine whether an area is involved in a task. If the STS is responsible for audio-visual integration in a TTC task, then TMS to the STS should disrupt the pitch effects evidenced in Experiment 1A. That is, a change in pitch should have no effect on TTC judgements compared to a constant tone. This result was evident only for rising tones, suggesting the involvement of the STS in the generating speeded predicted motion. The pitch effects observed in Experiment 1A and Experiment 2 implicate… Advisors/Committee Members: Grimshaw, Gina.

▼ Background: It is know that non-invasive peripheral and central stimulation techniques, such as transcutaneous electrical nerve stimulation, transcranial direct current stimulation and repetitive transcranial magnetic stimulation, can reduce the perception of pain. This could be shown in both chronic pain patients and healthy subjects. The exact mechanisms underlying stimulation techniques remain unclear. However, it was found that the application over the motor cortex revealed most promising results. The role of the motor cortex and the increased excitability remain to be investigated. Hypotheses: The aim of the study was to investigate the role of the motor cortex on pain modulation. Therefore, we tested the effects of different motor, somatosensory and motor- observation tasks executed by healthy volunteers. We evaluated the effects on behavioral (pressure pain threshold) and neurophysiological (motor cortical excitability via transcranial magnetic stimulation (TMS)) outcomes. Methods: The study was conducted in a randomized, blinded and controlled (placebo- tasks) manner. Within three experiments (A-C) a total number of 85 male, right-handed, healthy volunteers were enrolled. All study visits comprised the same assessments except the intervention tasks differed among the experiments, which was accomplished with subjects’ left hand: A. 15 volunteers performed three different motor tasks including motor learning with and without visual feedback as well as simple hand movements (cross-over design); B. 40 volunteers completed either a somatosensory tasks with or without visual feedback or a task with simple somatosensory input or a placebo-task including no somatosensory demand, respectively (parallel design); C. 30 volunteers performed either a motor-observation task (hand movements) or a placebo-task (movement of geometrical figures) (parallel design). The study involved the assessment of pressure pain threshold of both hands and the evaluation of cortical excitability via TMS (resting motor threshold (RMT), motor evoked potential (MEP), intracortical facilitation (ICF), short intracortical inhibition (SICI), and cortical silent period (CSP)). Data analyses included ANOVAs of pain thresholds and TMS-assessments as well as post-hoc t-tests. Results: The tasks tested induced hand-specific effects. They showed a significant increase in pressure pain threshold of the left target hand, which reflects a reduced perception of pain. In contrast, pressure pain threshold significantly decreased in the right hand indicating elevated pain perception. Placebo-tasks remained unchanged. ANOVA of TMS-assessments showed a significant difference among the three motor tasks. Only the task with simple hand movements significantly increased motor-cortical excitability, whereas the motor learning tasks did not. The observation of hand movements also resulted in significantly increased cortical excitability. In contrast, somatosensory tasks significantly reduced cortical excitability.

▼ Background and aims: The primary motor cortex (M1) controls voluntary motor behaviours. M1 has been identified to play a major role in the execution of voluntary corticospinal tasks as well as self-initiated corticobulbar tasks. However, the involvement of M1 in more complex corticubulbar tasks, such as swallowing, is not yet fully understood. Swallowing is quite different from other voluntary motor tasks as it has both voluntary and reflexive components. The degree of M1 involvement in the pharyngeal, or more reflexive, component of swallowing is unclear. Studies investigating the role of M1 in swallowing have yielded contradictory findings regarding the specific functional contribution of M1 to swallowing. Therefore, further investigation is warranted to clarify the role of M1 in pharyngeal swallowing. Discrete saliva or water swallowing has been utilized in most studies investigating neurophysiology of swallowing in health and disease. However, individuals most frequently complete multiple, consecutive swallows during the ingestion of liquid. Biomechanical differences between discrete and continuous water swallows have been identified using videofluoroscopic swallowing study (VFSS). However, no studies have investigated the pharyngeal pressure differences between these two swallowing tasks. Additional insights into task differences may be revealed through evaluation of pharyngeal pressure utilizing pharyngeal manometry. This research programme sought to clarify the role of M1 in reflexively and volitionally initiated pharyngeal swallowing. In order to understand M1 involvement in the execution of swallowing, comparative tasks that require known dependence on M1 were also included in this research programme. This research programme addressed the biomechanical changes in motor behaviours as a result of neural disruption during the performance of a number of motor tasks. This neural disruption was intrinsically generated through application of dual task (DT) paradigm and extrinsically generated using single pulse transcranial magnetic stimulation (TMS). A secondary aim of this research programme was to identify the differences in pharyngeal pressure generation between discrete and continuous swallowing. Methods: Twenty-four right handed participants (12 males, average age= 24.4, SD= 6.3) were recruited to this research programme. A number of motor tasks that vary in complexity were tested. These tasks included: volitional swallowing, reflexive swallowing, eyebrow movement, jaw movement and finger tapping with right, left, or bilateral index fingers. Participants performed multiple trials of several tasks in each study. Repetitions of tasks during a single session may affect performance due to factors such as fatigue or practice. A baseline study was undertaken to determine within-participant variability of measures across repeated trials. Following the baseline study, the role of M1 in pharyngeal swallowing was investigated in two main studies in counter balanced order. The role of M1 in…

▼ Introduction: There are a number of studies and systematic reviews suggesting potential chronic neurodegenerative effects of repetitive subconcussive head impacts. Indeed, most neuroimaging and some serum biomarker tests used in the literature generally present consistent evidence for negative effects of repetitive subconcussive head impacts. However, these tests have limited utility as side-line diagnostic tests. Purpose: Investigate whether two prospective side-line tests, sport concussion assessment tool 5 (SCAT 5) and transcranial magnetic stimulation (TMS), have enough sensitivity to detect relatively small and transient electrophysiological and cognitive changes in American football players who are very prone to repetitive subconcussive head impacts. The primary aim of this study is to investigate the effects of subconcussive head impacts on TMS and SCAT 5 performance by comparing contact with non-contact sport athletes. The secondary aim is to investigate the reproducibility and reliability of TMS and SCAT 5 in contact sport athletes. Methods: For the first section of the study, we assessed TMS and SCAT 5 measures on seventeen American football players (mean ±SD age: 23 ±7 years) and seventeen non-contact sport participants (mean ±SD age: 24 ±3 years) who were recruited for only one session. To assess the day-to-day reliability of each measure, the seventeen American football players were tested for a second time at least seven days following the first session. Results: Compared to the TMS day-to-day reliability analysis, SCAT 5 test scores presented poorer reproducibility and higher coefficients of variation (4–6% vs 10–66%, respectively). There were no significant differences in SCAT 5 test scores and corticospinal-silent period between contact and non-contact sport players. Conclusion: This is the first study to demonstrate similar electrophysiological and SCAT 5 characteristics between American football players and non-contact sport athletes. Also the electrophysiological changes observed are supported by our highly reliable and reproducible inter-day TMS data.

▼ Context: Symptomatic knee osteoarthritis (OA) affects 12.1% of adults over the age of 60 in the United States, making OA the leading cause of disability for older adults in the U.S. OA is a degenerative disease characterized by joint space narrowing, development of osteophytes, and articular cartilage degeneration. Symptoms associated with knee OA include pain, loss of motion, and decreased functional ability. These factors lead to disability, decreased quality of life, and a higher risk of comorbidities including obesity and cardiovascular disease. OA has been shown to also affect voluntary quadriceps strength and activation, further impairing function and quality of life. These neuromuscular alterations affecting the injured joint are referred to as central activation deficits (CAD). This affects the ability to activate motor neurons around the joint for recruitment during normal muscular contractions. This results in decreased muscle contraction capabilities and becomes a problem when these deficits persist and limit the ability to regain optimal muscle function. However, it is not fully understood how these deficits contribute to and worsen knee OA. Objective: To understand how knee OA influences quadriceps strength and central activation. Additionally, we sought to determine if a group-based exercise intervention could augment CAD in women with knee OA. Design: Pilot investigation with an embedded case series. Setting: Research laboratory. Methods: Baseline demographics were recorded on all participants. Baseline MVIC and CAR were measured using the burst superimposition technique. Baseline TMS measures (AMT, SICI, LICI, ICF) were calculated. Participants completed the 8-week therapeutic exercise intervention. Follow-up MVIC and CAR were recorded. Participants: Nine patients (age=57.11±5.28, height=1.71±0.06m, mass=90.52±22.58kg, BMI=30.81±6.69) completed baseline strength and CAD measures. Three patients (age=59.67±2.89, height=1.70±0.00m, mass=85.13±8.95kg, BMI=29.46±3.10) completed baseline strength and CAD testing followed by the 8-week therapeutic exercise intervention and follow-up testing. Results: At baseline, quadriceps strength was 1.70±0.74 Nm/kg and CAR was 0.97±0.03. TMS measures at baseline were: AMT=46.50±7.85%, SICI=0.52±0.27, ICF=2.17±0.97, and LICI=0.36±0.21.For the subset of women who completed the intervention, strength decreased from baseline to follow-up (2.22±0.83 Nm/kg and 1.67±0.67 Nm/kg, respectively), while CAR remained relatively unchanged 0.99±0.01 and 0.97±0.03. Conclusions: Results show similarities among TMS between this and other studies done on this type of patient population. Quadriceps strength decreased after an 8-week therapeutic exercise intervention, which is counterintuitive. Additional studies are required to further understand the role of quadriceps central activation in the osteoarthritic process so that appropriate interventions can be developed and implemented.

▼ Recently separate control systems for postural and movement control have been found in primates. Dystonia is a hyperkinetic movement disorder and its cause it not well understood. We have observed that dystonia patients have preserved fine movement control, but difficulty maintaining the appropriate and sustained posture that supports these movements. Postural control requires multiple modalities of sensory input such as cutaneous, proprioceptive, vestibular and visual stimuli. Through clinical observation, dystonia is improved by sensory alteration. Sensorimotor integration dysfunction has been observed in dystonia patients using multiple methods of study, such as neuroimaging and neurophysiological studies. This thesis investigates if dystonia is secondary to abnormalities in postural control rather than movement control mechanisms, using transcranial magnetic stimulation (TMS) and surface electromyography (EMG). In order to understand how to interpret neurophysiological data collected from focal cervical dystonia patients, we analysed the clinical characteristics and demographics of focal cervical dystonia and writer’s cramp patients. We also compared our findings to the results from a larger cohort which was derived from Dystonia Coalition study, an international collaborative study, in which our participants contributed. Cervical dystonia patients are more likely to have associated tremor and a geste antagoniste than writer’s cramp patients, whereas task-specificity is more common in writer’s cramp. Cervical dystonia severity and pain scale had a strong positive correlation with cortical silent period, whereas the writer’s cramp severity scale had a strong negative correlation with cortical silent period. The differences in clinical characteristics and neurophysiological findings between focal cervical dystonia and writer’s cramp patients reflect differences in pathophysiology and neurophysiological studies of focal dystonia need to analyse dystonia subtypes separately. The differences in muscle activity generation and co-contraction of agonist and antagonist muscle groups were analysed in normal controls and focal dystonia patients during comparable movement and postural control tasks. It was hypothesized that during a postural control task, there would be an increase in agonist and antagonist co-contraction, which is a known neurophysiological correlate in dystonia. Using surface EMG, we found no increase in agonist/antagonist co-contraction during posture maintenance in dystonia patients, contrary to our hypothesis. However, during a non-dystonia inducing task, there was exaggerated compensatory postural muscle activity during the movement phase of voluntary wrist extension in both cervical dystonia and writer’s cramp patients. In order to explore differences in the behaviour of the motor cortex during postural versus movement control in healthy participants, transcranial magnetic stimulation was used to measure cortical excitability and inhibition. A novel paradigm was developed where participants…

Il sonno e la veglia vengono comunemente considerati come due stati distinti. L’alternanza tra essi, la cui presenza è stata dimostrata in ogni specie animale studiata fino ad oggi, sembra essere una delle caratteristiche che definisce la nostra vita. Allo stesso tempo, però, le scoperte portate alla luce negli ultimi decenni hanno offuscato i confini tra questi due stati. I meccanismi del sonno hanno sempre affascinato i neurofisiologi, che infatti, nell’ultimo secolo, li hanno caratterizzati in dettaglio: ora sappiamo che all’attività del sonno sottostà una specifica attività neuronale chiamata slow oscillation. La slow oscillation, che è costituita da (ancora una volta) un’alternanza tra periodi di attività e periodi di iperpolarizzazione e silenzio neuronale (OFF-periods), è la modalità base di attivazione del cervello dormiente. Questa alternanza è dovuta alla tendenza dei neuroni surante lo stato di sonno, di passare ad un periodo silente dopo un’attivazione iniziale, una tendenza a cui viene dato il nome di bistabilità neuronale. Molti studi hanno dimostrato come la bistabilità neuronale tipica del sonno ed i relativi OFF-periods, possano accadere anche durante la veglia in particolari condizioni patologiche, nelle transizioni del sonno e durante le deprivazioni di sonno. Per questo motivo, se accettassimo che la bistabilità neuronale e gli OFF-periods rappresentino una caratteristica fondamentale del sonno, allora dovremmo ammettere che stiamo assistendo ad un cambio di paradigma: da una prospettiva neurofisiologica il sonno può intrudere nella veglia. In questa tesi ho analizzato i nuovi -fluidi- confini tra sonno e veglia e le possibili implicazioni di questi nel problema della persistenza personale attraverso il tempo. Inoltre, ho studiato le implicazioni cliniche dell’intrusione di sonno nella veglia in pazienti con lesioni cerebrali focali di natura ischemica. In particolare, i miei obiettivi sono stati: 1) Dimostrare come la bistabilità neuronale possa essere responsabile della perdita di funzione nei pazienti affetti da ischemia cerebrale e come questo potrebbe avere implicazioni nello studio della patofisiologia dell’ischemia cerebrale e nella sua terapia; 2) Stabilire le basi per un modello di sonno locale presente nella vita di tutti i giorni: la sensazione di sonnolenza. Infatti, essa potrebbe riflettere la presenza di porzioni di corteccia in stato di sonno, ma durante lo stato di veglia; 3) Difendere il criterio biologico di identità, che troverebbe nell’attività cerebrale la continuità necessaria al mantenimento della nostra identità nel tempo.

Sleep and wakefulness are considered two mutually exclusive states. The alternation between those two states seems to be a defining characteristic of our life, a ubiquitous phenomenon demonstrated in every animal species investigated so far. However, during the last decade, advances in neurophysiology have blurred the boundaries between those states. The mechanisms of sleep have always intrigued neurophysiologists and great advances have been made over…

▼ Background Repetitive Transcranial Magnetic Stimulation (rTMS) of the cerebral cortex has been previously applied as a non-invasive therapy for neurological conditions due to its potential to modify cortical excitability through neuroplasticity. Cerebellar stimulation has the potential to modify cortical excitability because of its predominantly inhibitory connections with the motor cortex and other cortical areas. Previous studies have shown that cerebellar rTMS, including theta burst stimulation (TBS) can modulate excitability in the motor cortex, but the findings have been variable. The aim of this study was to investigate the effects of 30Hz cerebellar TBS on motor evoked potentials (MEP) and TMS-evoked cortical potentials (TEP). Method Combined TMS and electroencephalography (TMS-EEG) was carried out on 16 healthy participants, aged 21-30 years. Each subject was studied in three separate sessions, in which 30Hz intermittent TBS (iTBS), continuous TBS (cTBS) or sham stimulation at stimulus intensity of 80% or 90% of active motor threshold (AMT) was applied to the right cerebellar hemisphere. Each session consisted of active and resting MEP and TEP recording from the left motor cortex before and after TBS. EEG recordings were analysed offline using EEGLAB software and independent component analysis (ICA) was used to remove artifacts. TEP were extracted and averaged. Mean N100 waveform amplitudes were measured before and after each treatment protocol. Post stimulation values for all parameters were compared using mixed model ANOVA, with pre-treatment values as covariates. Results The TBS protocol at 90% of AMT stimulus intensity produced a significant decrease in amplitude of the resting MEP after cTBS compared to sham TBS, F(2,13)= 4.87, p=0.035. Cortical silent period (CSP) was increased following iTBS, compared to sham, F(2,13)= 4.87, p=0.026. The effects of 80% TBS on MEP were not significant The mean N100 amplitude was significantly greater after iTBS than sham TBS using 80% or 90% stimulation F(2,348)=197.80, p < 0.001 and F(2,455)=6.17, p = 0.02, respectively. Conclusion The study demonstrated that 30Hz cerebellar cTBS at 90% AMT produced a reduction in overall excitability of the contralateral motor cortex, as shown by reduced resting MEP amplitude. Although iTBS produced an increase in the CSP and the N100 amplitude, both thought to reflect intracortical inhibition, there was no significant effect of iTBS on MEP amplitude. As this measure is dependent on the net effect of inhibitory and facilitatory networks in the cerebral cortex, it is possible that an increase in intracortical inhibition cancelled out the inhibitory effects. These findings provide further evidence that cortical excitability can be modulated through cerebellar TBS. Cerebellar TBS has potential as a therapeutic modality for a number of neurological conditions where there is abnormal cortical excitability, including epilepsy, dystonia and Parkinson’s disease. Future investigation of its effects is required before it can be… Advisors/Committee Members: Hammond-Tooke, Graeme (advisor).

▼ Neuromuscular electrical stimulation (NMES) has become an increasingly popular rehabilitative treatment approach for swallowing disorders (dysphagia). However, its precise effects on swallowing biomechanics and measures of swallowing neurophysiology are unclear. Clearly defined NMES treatment protocols that have been corroborated by thorough empirical research are lacking. The primary objective of this research programme was therefore to establish optimal NMES treatment parameters for the anterior hyo-mandibular (submental) musculature, a muscle group that is critically involved in the oral and pharyngeal phases of swallowing. Based on previous research, the primary hypothesis was that various NMES treatment protocols would have differential effects of either enhancing or inhibiting the excitability of corticobulbar projections to this muscle group. The research paradigm used to test this hypothesis was an evaluation of MEP amplitude and onset latency, recorded in the functional context of volitional contraction of the submental musculature (VC) and contraction of this muscle group during the pharyngeal phase of volitional swallowing (VPS, volitional pharyngeal swallow). Outcome measures were recorded before and at several time points after each NMES treatment trial. This methodology is similar to, but improved upon, research paradigms previously reported. Changes in corticobulbar excitability in response to various NMES treatment protocols were recorded in a series of experiments. Ten healthy research participants were recruited into a study that evaluated the effects of event-related NMES, whereas 15 healthy research participants were enrolled in a study that investigated the effects of non-event-related NMES. In a third cohort of 35 healthy research participants, task-dependent differences in corticobulbar excitability were evaluated during three conditions of submental muscle contraction: VC, VPS and submental muscle contraction during the pharyngeal phase of reflexive swallowing (RPS, reflexive pharyngeal swallowing). Event-related NMES induced frequency-depended changes in corticobulbar excitability. NMES administered at 80 Hz facilitated MEP amplitude, whereas NMES at 5 Hz and 20 Hz inhibited MEP amplitude. No changes were observed after NMES at 40 Hz. Maximal excitatory or inhibitory changes occurred 60 min post-treatment. Changes in MEP amplitude in response to event-related NMES were only observed when MEPs were recorded during the VC condition, whereas MEPs recorded during the VPS condition remained unaffected. Non-event-related NMES did not affect MEP amplitude in either of the muscle contraction conditions. Similarly, MEP onset latencies remained unchanged across all comparisons. MEPs were detected most consistently during the VC contraction condition. They were less frequently detected and were smaller in amplitude for the VPS condition and they were infrequently detected during pre-activation by RPS. The documented results indicate that event-related NMES has a more substantial impact on…

▼ Humans have an automatic tendency to imitate, as illustrated by unconscious mimicry during social interactions and behavioral interference effects in the laboratory. Automatic imitation is thought to arise from activation of the imitative motor representation during action observation, which is likely mediated by the overlapping representation of observed and executed actions in the mirror neuron system. In contrast to mechanisms of automatic imitation, models attempting to explain how automatic imitative tendencies are brought under intentional control are incomplete. In this dissertation, I use functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS) to measure and disrupt neural activity during imitation interference tasks to expand current models of imitation control. In particular, I focus on dissociating imitation control from control over a related prepotent response tendency – spatial compatibility – to determine (1) whether control mechanisms involved in overcoming automatic response tendencies evoked by action observation utilize a dedicated mechanism and (2) whether imitation control involves modulation of the mirror neuron system. In addition, I explore the hypothesis that imitative control mechanisms may differ depending on whether control is exerted in reaction to a stimulus (after the automatic response tendency has been evoked) or in advance of a stimulus (reducing the degree of automatic response activation in the first place).Results indicate that neural systems involved in reactive control of imitation are dissociable from those involved in controlling spatially compatible response tendencies. I propose a model of reactive imitation control involving interactions between prefrontal control regions and the mirror neuron system. In contrast to reactive control, I found no evidence of a dissociable preparatory imitation control mechanism in an fMRI study. However, TMS results suggest that preparatory control of imitation involves suppression of MNS activity, which can be reconciled with neuroimaging results through a general control that reduces the influence of visual input on the motor system. Thus, regardless of the timing, imitation control seems to involve modulation of MNS activity through interactions between general cognitive control systems and the more specific imitation circuits.
