▼ Maintaining accurate memory depends on both the ability to recognize old information and the ability to reject new information that has not been previously encountered. Research has shown that it is difficult to reject new information that bears resemblance to previously encountered information and individuals instead often falsely identify such new information as old. It has been posited that in the case of high relatedness between new and old information, recalling elements of old information can facilitate the rejection process as inconsistencies between new and old information can be identified. Recalling studied information to facilitate rejection of new items at retrieval has been termed ‘recollection rejection’ and is an excellent strategy for suppressing false memories. Despite the fact that recollection rejection is posited to engage a mechanism similar true recollection, previous neuroimaging studies have not evaluated to the overlap between the neural correlates of true recollection and recollection rejection. Thus, the present study sought to evaluate the neural basis of recollection rejection within a perceptual false memory paradigm. Results demonstrated that recollection rejection engaged a fronto-parietal network that has been posited to support retrieval monitoring processes. Critically, neural overlap between recollection rejection and true recollection was limited to one cluster in ventral visual cortex. Thus, there was little evidence that recollection rejection relies on a true recollection mechanism. Regarding aging, few behavioral studies have evaluated older adults’ ability to use recollection rejection as a strategy for suppressing false memories, despite the wealth of research showing age-related increases in false memories. Further, no neuroimaging study has done so. In particular, given age deficits in true recollection processing, it is possible that difficulties engaging recollection represent a common cause of age-related deficits in true memories and age-related increases in false memories. However, while the present study revealed a behavioral age deficit that was specific to rejecting related lures using recollection rejection, very few neural differences between age groups were identified. While there was some evidence of age-related increases in neural activity associated with recollection rejection, there was far more neural activity that was common across age groups. Thus, when older adults make successful recollection rejection responses, they do so based on similar cognitive and neural processes as young adults.

▼ We are constantly bombarded with stimuli from multiple sensory sources in the environment of our natural world. The innate behavioral responses to the environment, therefore, are based on our brains’ ability to integrate distinct and complex sensory information into a comprehensive and understandable percept (1). Therefore, multisensory integration is a phenomenon that involves combining multimodal sensory information from a target stimulus into a coherent signal. Despite substantial knowledge of the fundamental processes involved in multisensory integration, there is still much to be learned because majority of studies have focused on one sensory modality at a time (2). One particular aspect that is largely overlooked is the interplay between the visual and olfactory systems (3). Despite olfaction being a vestigial sense, landmark studies have consistently demonstrated, strong behavioral and physiological responses to olfactory stimuli even at levels below conscious perception, (4-7). Behavioral, anatomical, and neurofunctional evidence exists supporting the likelihood of an innate olfactory-visual functional connection in the human brain (8-43). Furthermore, pioneering research on the topic of olfactory-visual interactions has utilized fMRI to delineate the neural networks underlying the interplay between these two sensory systems (44-55). However, many of these studies employed fMRI paradigms to better understand the influence of visual information over olfactory processing. This dissertation aimed to utilize olfactory-visual association fMRI paradigms to better elucidate the reciprocal relationship between the olfactory and visual systems in the human brain. The overall goal was to develop a more comprehensive model of the neural networks underlying the human olfactory function. Olfaction is the most studied chemosensory system, however, the functioning of this network is still not well understood because of its complicated neuroanatomical organization (56). This dissertation, therefore, sought to elucidate several unknown aspects of the functional connection between the olfactory and visual systems by testing several hypotheses about this innate connection. First, Chapter 2 of this dissertation focused on investigating the role of congruence during the formation of olfactory-visual associations. It was hypothesized that olfactory-visual associations could be rapidly formed by a neutral, non-lexical abstract visual symbols, as evidenced by significant olfactory system activation during testing conditions consisting of presenting a visual cue that was previously paired with an odor compared to an unpaired visual cue. It was also hypothesized that a lexical, semantically congruent visual cue, would produce greater olfactory-visual activation during both the acquisition and testing phases compared to a lexical, semantically incongruent visual cue or a neutral, non-lexical symbol. The results reinforced that rapid olfactory-visual associations could be formed by neutral, non-lexical visual cues, via… Advisors/Committee Members: Qing X.

▼ Previous research has identified a series of impairments in neuroconnectivity in autism, leading to the under-connectivity theory. However, several recent studies provided evidence that neural network was actually over-connected, but not under-connected as previously thought, in autism. These apparent discrepancies can be attributed to the drawbacks in study design and statistical methods. First of all, most previous studies suffered from small sample size, a problem that rendered these studies to be underpowered. Secondly, these studies failed to account for two critical sources of variation: difference among subjects and variation among sites. As a result, the estimated difference between patient and control and its standard error were not accurate. This not only decreased the efficiency of analysis but also lead to biased inferences. In this work we took advantage of the largest autism database, the Autism Brain Imaging Data Exchange(ABIDE). Our analyses included 361 subjects from 8 medical centers. We believed that the sample size in this work avoided the 'underpower' issue in most previous studies. By implementing EM algorithm, which iterated between E step that used empirical Bayesian to estimate random effect and M step which evaluated fixed effect via MLE, we were able to obtain accurate estimate of difference between patient and control and its standard error. After applying false discovery rate control, we identified 12 links with significant difference between patient and control. The second statistical methodology that we implemented in this work was Bayesian hierarchical modeling. In the work, we fitted this model to ABIDE data. The FDR control approach in the above-mentioned methods failed to account for the correlation among statistical tests. As fMRI data was obtained from different regions of the same brain, it was highly unlikely that the statistical tests were independent. Principal factor approximation was recently proposed to implement FDR control in the presence of dependence structure. We applied PFA to the ABIDE dataset and identified links with significant difference in autism. Lastly, the three above-mentioned methods did not take into account site effect, which could be an important source of variation. We performed meta-analysis by conducting separate analysis by site and then combined analysis with weight equal to the inverse of standard error. Meta-analysis identified additional significant links.

▼ Background: Alzheimer’s disease (AD) is a neurodegenerative disorder for which there is presently no cure. As a result, there is a critical need to improve upon early detection methods through the identification of ideally non-invasive biomarkers, such as functional magnetic resonance imaging (fMRI). Recently, novel approaches to the analysis of resting-state fMRI data have been developed that focus on the moment-to-moment variability in the blood oxygen level dependent (BOLD) signal. However, the findings on BOLD signal variability have thus far been equivocal, with some findings showing decreased BOLD variability with age and cognitive decline, and others suggesting that increased BOLD fluctuations may serve as a physiological signal reflecting underlying cerebrovascular challenges. Given the paucity of research in this area, the objective of the current study was to investigate BOLD variability as a novel early biomarker of AD and its associated psychophysiological correlates. Method: Neuroimaging and cognitive data were obtained from the Alzheimer's Disease Neuroimaging Initiative (ADNI) 2 database from 19 participants with AD (mean age = 72.7 ± 6.5) and 19 similarly-aged controls (mean age = 74.7 ± 6.9). All analysis steps were performed using tools within the Functional MRI of the Brain Software Library (FSL). For each participant, a map of BOLD signal variability (SDBOLD) was computed as the standard deviation of the BOLD timeseries at each voxel within both grey and white matter regions. Firstly, group comparisons were performed to examine global differences in resting state SDBOLD in AD versus healthy controls. Correlations were then examined between participant SDBOLD maps and (1) ADNI-derived composite scores of memory and executive function and (2) neuroimaging markers of cerebrovascular status (total white matter hyperintensity [WMH] burden, as computed from FLAIR scans). Results: Between-group comparisons revealed significant (p < 0.05) increases in SDBOLD in patients with AD relative to healthy controls in right-lateralized grey and white matter frontal regions, including the superior frontal and precentral gyri, and widespread regions of the corona radiata. Due to the novelty of the current study, secondary analyses investigating the association between SDBOLD and psychophysiological correlates were examined with a more liberal threshold (p < 0.1). Results revealed that lower memory scores were associated with greater SDBOLD in the medial temporal lobe and adjacent structures in the healthy control group. Conversely, higher total WMH burden was associated with greater SDBOLD in highly localized grey and white matter regions in the healthy control group. No association between SDBOLD and cognitive or cerebrovascular measures was identified in the AD group. Conclusion: The current study provides proof of concept that a novel resting state fMRI analysis technique that is non-invasive, easily accessible, and clinically compatible, can differentiate patients with AD from healthy controls.

Improving stroke recovery is a topic of considerable interest in the developed world. Motor deficits following stroke can significantly impact quality of life, and motor rehabilitation strategies are urgently needed to promote brain recovery. One technique that has had therapeutic success in other domains is neurofeedback (NF), a strategy whereby a person is trained to gain volitional control of their neurological activity. The NF technique has proven efficacious in disorders ranging from epilepsy to attention deficit disorders based on feedback of electroencephalography (EEG) signals, and the potential exists for NF applications in the recovery of motor function following stroke. Using functional magnetic resonance imaging (fMRI), NF can be applied to precisely defined regions of interest (ROIs), facilitating the targeted treatment of affected functional areas. The combination of fMRI and NF is still relatively new, and much work remains in the characterization and optimization of fMRI NF strategies. In a two-pronged approach, this thesis focuses on the application of ROI-based NF to the motor system using traditional fMRI measurements and also the development and analysis of acquisition strategies intended for use in ROI-based NF. First, a study of the mechanisms governing the successful application of NF in primary motor cortex ROIs is presented, using kinaesthetic motor imagery (imagining the sensation and execution of movement) to engage the motor system. Second, an investigation of fMRI signal contrast enhancement properties using multi-echo fMRI acquisition methods in dense sampling regimes is considered. Third, a novel acquisition method is introduced, designed using parallel MRI principles to provide fast and detailed sampling of fMRI signals in selected ROIs, called Constrained Source Space Imaging (CSSI). To conclude, the potential future directions for fMRI NF research and the CSSI technique are discussed, including thoughts toward the continued development of NF as a potential motor therapy for stroke patients.

▼ Previous fMRI studies have demonstrated that older adults who perform as well as young adults on certain cognitive tasks recruit additional brain regions relative to younger adults while performing these tasks. This phenomenon has been interpreted as a compensatory response and may reflect an effort to maintain performance in the face of increasing changes in cognitive difficulty or age-related brain changes in structure and/or function. Whether the compensatory response is specific to older adults or represents a more general response of any individual to increasing task difficulty is unclear. The present fMRI experiment explored age differences in brain activity associated with increases in task difficulty in two tasks, an episodic-retrieval task that is expected to be difficult for older compared to young adults, and a lexical-semantic task that is expected to be more difficult for young compared to older adults. In the lexical-semantic task, participants judged whether pairs of words were synonyms or antonyms. In the episodic task that followed, participants made yes/no memory judgments for the word pairs previously presented. Difficulty was manipulated using word frequency -low frequency words are more difficult in the lexical-semantic judgment task and easier in the episodic task. Young (ages 18-24) and older healthy adults (ages 60-83) were scanned on a 3T GE magnet using a single-shot spiral pulse sequence. Behavioral results showed a double dissociation – older adults were adversely affected by word frequency in the episodic but not the semantic task, while young adults were adversely affected by word frequency in the semantic but not the episodic task. Both groups showed activation in similar task-related and task-general regions regardless of difficulty level). Age-related differences were observed for task-specific and linear increases due to difficulty. Linear increases in fMRI activation were associated with younger adults showing increased task difficulty in bilateral task-related regions during the lexical semantic task, whereas in the episodic retrieval task only activating bilateral posterior cortices. As difficulty increased, older adults showed unilateral brain activations: left regions for the lexical-semantic task and medial and right hemisphere regions for the episodic retrieval task. Most importantly, difficulty load increases paralleled the groups' behavioral results: younger adults showed greater increases in activity in the lexical-semantic task compared to older adults, but not in the episodic retrieval task, whereas older adults showed the opposite pattern, with greater increases in activation only in the episodic task when compared to younger adults. Thus, younger and older adults recruit regions differently in response to increases in difficulty. Our results suggest that increases in fMRI activation as difficulty increases occur as an interaction to deal with task difficulty and the inherent abilities of the individuals, rather than occurring only in older adults, or in older adults… Advisors/Committee Members: Ryan, Lee T (advisor), Ryan, Lee T.

▼ What determines whether an experience is encoded to memory? One factor is reward-based motivation: we are more likely to remember information if we believe it will lead to future rewards. Memory critically depends on the integrity of the medial temporal lobes (MTL). Notably, the MTL is comprised of subregions that are hypothesized to serve different functions in memory and may be differentially influenced by reward. The present research examines how reward-based motivation influences associative memory processing within MTL subregions of the human brain. In two high-resolution functional magnetic resonance imaging (fMRI) studies, a high-value or low-value monetary cue preceded a pair of objects indicating potential reward for successful retrieval of the association on a later memory test. Memory was enhanced for pairs preceded by high-value compared to low-value reward cues, however participants differed in the degree to which reward value influenced memory. In fMRI Study 1, the behavioral effect of reward on memory was associated with reward-related activation changes in hippocampal subregions dentate gyrus/CA₂,₃ and enhanced connectivity between dentate gyrus/CA₂,₃ and reward-related midbrain regions during encoding and retrieval. In fMRI Study 2, patterns of MTL activations represented reward context, showing greater consistency among events of the same reward value than among events of different reward values. Successful memory formation was associated with enhanced hippocampal reward representations during the anticipatory cue phase prior to object pair encoding. During object pair encoding, the degree of reward representation in hippocampus and more specifically dentate gyrus/CA₂,₃ was associated with individual differences in the behavioral effect of reward on memory. Finally, a series of behavioral studies demonstrate that during motivated learning, associative memory accuracy increases monotonically with increasing reward value, and may be enhanced when participants must maintain information about reward cues in short-term memory prior to encoding. These findings indicate that reward-based motivation enhances associative memory processing specifically within dentate gyrus/CA₂,₃ through interactions with reward-related midbrain regions. Furthermore, these results suggest that associative memory may be facilitated when information about reward context is incorporated into stored memory representations. Collectively, these findings shed light on fundamental mechanisms through which reward impacts associative memory. Advisors/Committee Members: Preston, Alison R.

▼ The goal of the human sensory system is to build a useful internal representation of the world. In vision, this means that the brain categorizes and identifies all the objects and actions that are being observed. In language, it means that the brain understands the meaning of each word that is being perceived, and integrates across words to understand the meaning of a narrative. Both of these processes can be seen as extracting the meaning, or semantic content, from a dense stream of sensory information. We know very little about how the brain accomplishes these feats. Indeed, entire fields of research (computer vision and natural language processing) are devoted to reproducing on a computer feats of understanding that the human brain accomplishes with ease. We may be able to gain insight into these processes by studying how the semantic information extracted from visual and linguistic stimuli is represented in the brain.This dissertation describes three functional magnetic resonance imaging (fMRI) experiments that have helped to reveal how visual and linguistic semantic information are represented across the human cerebral cortex. These experiments relied on a relatively new fMRI analysis methodology known as voxel-wise modeling (VM). Although this methodology was developed for modeling how the brain represents the structure of visual information, it was adapted here for modeling representation of the extremely complex semantic information present in natural movies and natural narrative stories. The first experiment (Chapter 2) showed that information about object and action categories present in natural movies is represented in a low-dimensional semantic space that is shared across subjects. Projecting this semantic space across the cortex revealed that semantic information is represented in broad cortical gradients that cover a surprising amount of the cortical surface. The second experiment (Chapter 3) showed that information about the semantic content of narrative spoken stories is also represented in a low-dimensional space that is shared across subjects. To model the complex cortical maps for this semantic space a new technique was developed called PrAGMATiC (Probabilistic And Generative Model of Areas Tiling the Cortex). This new technique revealed that the cortical semantic maps can be explained by about 230 functional areas that cover much of the prefrontal cortex, temporoparietal junction, precuneus, and temporal cortex. Finally, the third experiment (Chapter 4) showed that a novel hierarchical logistic regression (HLR) model could accurately decode the categories of objects and actions present in natural movies from fMRI responses.

▼ Despite an emerging link between alterations in motivated behavior and a lack of sleep, the impact of sleep deprivation as well as the potential benefit of sleep, when it is achieved, on human brain mechanisms of reward and punishment remain largely unknown. Targeting these unanswered questions, this thesis aims to determine the impact sleep loss on human brain incentive processing in topics of 1) food desire and 2) monetary gains and losses. From these investigations four main findings have emerged that make up the first four chapters of this report: 1) In the context of food choices, sleep deprivation leads to significantly decreases activity in appetitive evaluation regions within the human frontal cortex and insular cortex during food desirability choices, combined with a converse amplification of activity within the amygdala ultimately leading to increased high calorie food choices. 2) In the context of monetary rewards and losses, sleep deprivation did not lead to measurable changes in activation to the anticipation of rewards and losses in the nucleus accumbens or insula respectively. However, sleep deprivation did lead to diminished medial prefrontal cortex responses to gain outcomes and increased anterior insula response to loss outcomes. 3) Although there were no observable sleep deprivation group effects on anticipation of monetary gains and losses, there was a significant interaction of sleep deprivation with a trait dopamine transporter genetic polymorphism that determined the impact of sleep deprivation on anticipatory response to gain and loss in the nucleus accumbens and anterior insula respectively. 4) In the context of learning from monetary incentives, sleep deprivation led to a specific deficit in the ability to learn from monetary gains but no change in the learning profile for monetary losses. Finally, in addition to these four findings on the impacts of sleep deprivation on human incentive processing, the final chapter (5) focuses on the relationship between sleep, when it is achieved, and next day reward responsivity. Here there is a significant relationship between individual differences in REM sleep beta power and next day nucleus accumbens response to anticipation of rewards. Beyond these basic scientific insights, such results offer potential clinical relevance given that sleep disruption is highly co-morbid with numerous psychiatric and neurological conditions associated with dysfunctional dopaminergic reward processing (e.g., Parkinson's disease, substance abuse, and obesity). Such findings further indicate that sleep intervention may represent an under appreciated and novel therapeutic target particularly for disorders of the reward system.
