Neural processing of semantic content in movies
… through eye movements. The full extent of neural responses to features such as motion, film cuts and eye movement behavior has not been established. The main hypothesis of this thesis is that complex multimodal and semantic stimuli in naturalistic movies engage a widespread ensemble of …

The Neural Processing of Face-like Stimuli
… emotional and social information, yet the neural mechanisms underlying their perception across different types of face-like stimuli remain incompletely understood. This dissertation will report an EEG - multivariate pattern analysis (MVPA) study that investigated how emotional expressions …

Neural Processing in the Three Layer Turtle Visual Cortex
In this thesis we investigate neural processing in turtle visual cortex. To this end, we characterize the nature of both spontaneous, ongoing neural activity as well as activity evoked by visual stimulation. Data are collected from whole brain eye-attached preparations, recording with extracellular …

Neural processing of chemosensory information from the locust legs
Tarsal chemoreceptors in phytophagous insects can provide information on the chemical nature of the leaf surface, and are thus potentially important in host plant discrimination. Ovipositing Pieris brassicae, for example, drum the surface of leaves with their tarsi and tarsal chemoreceptors have …

A role for hippocampal and midbrain neural processing in context-dependent spatial memory
… context, it has not been demonstrated that VTA neural activity is modulated by contextual information. Therefore, I recorded the activity of VTA neurons as rats performed a similar spatial memory task under varying contextual conditions. I found that the activity of reward-related VTA neurons …

Psychological and Neural Processing of Social Risk and Discrepancy in Major Depressive Disorder
… aims to extend our understanding of social processing in MDD by testing hypotheses generated from a socio-evolutionary theoretical framework of MDD, with particular emphasis on the Social Risk Hypothesis of Depressed Mood, which conceptualises depressed mood as an adaptive response to …

Psychological and Neural Processing of Social Rejection and Inclusion in Major Depressive Disorder
… aimed to extend the existing psychological and neural basis of social processing in Major Depressive Disorder. This investigation was an attempt to resolve current conflicts and gaps in the social affective neuroscience literature regarding social functioning in depression. Chapter 1 consisted …

Studies on the neural processing of conspecific songs in the cricket Teleogryllus oceanicus (Le Guillou)
This study involved investigations into the neural processing of auditory information by the Australian field cricket Teleogryllus oceanicus in relation to the identification of its conspecific songs. T. oceanicus males produce three song types related to three different behavioural strategies. …

Decoding Neural Processing of Linguistic Features From Large-Scale Intracranial Recordings and Naturalistic Language Stimuli
… in the brain, utilizing high-resolution neural recording. Using data from the Brain TreeBank, a large-scale multimodal dataset of recorded brain activity, we fit Generalized Linear Models (GLM) to map language and vision stimuli to induced brain activity. This framework allows us to …

An event related potential study of the role of religious commitment in the neural processing of moral judgements
… to examine how religious commitment impacts the neural processing of morally laden information. Event-related potentials were recorded while 35 participants, scoring either high or low on the Religious Commitment Inventory-10, read scenarios describing a social interaction with one of three …

Genetic Modulation of the Neonatal Neural Processing of Speech at High and Low Familial Risk for Developmental Dyslexia
… study that aims to identify potential neural oscillatory deficits in neonates associated with genetic and familial risk of dyslexia. Poor awareness of speech sounds (phonology) is the hallmark of dyslexia, across all languages studied so far. Despite the identification of several …

Sex Differences in Risky Decision-Making Neural Processing and Its Link to Problematic Substance Use in Adolescents at Risk for Substance Use Disorders
… sex differences in risky decision-making neural processing among adolescents with externalizing disorders (EXT), like ADHD and conduct disorder, have been understudied though EXT youth are at high risk for developing substance use disorders (SUDs), partially due to impaired …

Neuroimaging metrics of drug- and food-cue reactivity as a function of psychopathic traits, substance use, and substance dependence
… between psychopathy and drug- and food-related neural reactivity. In the first study, we assessed the relationship between psychopathic traits and neural reactivity among 47 cocaine-dependent and 58 non-dependent participants. The cocaine-dependent group exhibited a neural processing bias …

Neural Circuitry Deficits Associated With Dysfunctional Myelin
… study on the impact of dysfunctional myelin on neural processing.</p> <p>Undoubtedly, slowed conduction velocity along myelinated axons increases temporal dispersion and, consequently, degrades information transfer between neural circuits. Herein, this dissertation work explores the impact of …

Hypnotizability and Corpus Callosum Morphology
… Furthermore, highs appear to have faster neural processing than lows. The present study investigated differences between lows and highs in morphological volume of some brain structures associated with inhibitory and excitatory neural processing, particularly the corpus callosum (CC). …

Neurology of Attention: Interhemispheric Processing Modulates Attention in the Stroop Task
… interhemispheric communication helps modulate processing during increased attentional demand. The data suggest that interhemispheric processing (1) is not a static, but instead varies with task demands, (2) produces non-random responses to attentional demands, and (3) is a unique form of neural …

Altered Perceptions Discerning the Natural from the Virtual in Extended Reality
… Our view of reality is shaped by our senses, neural processing and learned meanings. Pondered by many fields of inquiry, the concept of reality is bantered around with careless disregard when applied to virtual, augmented and mixed applications, all under the umbrella of extending reality. The …

About turn:neural mechanisms underlying visual processing of rotated letters and digits
This thesis explores neural activity associated with processing of rotated alphanumeric characters, focusing particularly on linear and quadratic trend components of orientation-dependent activity. Choice of these components was driven by results of reaction-time (RT) studies; judging whether …
