IDENTIFICATION OF NEUROMARKERS USING STRUCTURAL AND FUNCTIONAL NEUROIMAGING
… research, the spatially and temporally complex neuroimaging data were used to identify neuromarkers that aids in quantifying a brain’s health. In the first part, a comparison of static and dynamic functional connectivities was made to study their efficacies in identifying intrinsic individual …

Functional neuroimaging studies of peripheral inflammation-related depression
… may elicit depressive symptoms via brain functional abnormalities. In Chapter 2 I present a more focused discussion in the form of a literature review of current brain functional neuroimaging studies on inflammation-linked depression. I noted through this endeavor that the body of …

Dissecting emotion : towards a functional neuroimaging probe for affective disorders
The goal of this research was to develop a functional magnetic resonance imaging paradigm for use in investigating major depressive disorder. Functional neuroimaging studies of depression have reported altered resting brain metabolism and altered responses to simple emotion paradigms in the …

A functional neuroimaging family study of facial emotion perception in schizophrenia
… vulnerability marker for the disorder. Previous neuroimaging studies investigating these deficits were limited by confounding task demands that may recruit other impaired cognitive processes in schizophrenia. We used a family study design along with a passive viewing task to investigate brain …

Advances in Optical Coherence Tomography and Microscopy for endoscopic applications and functional neuroimaging
Optical Coherence Tomography (OCT) is a developing medical imaging technology that generates micron resolution cross-sectional images of subsurface internal tissue structure in situ and in real time, without the need to remove and process specimens. Previous studies have suggested that OCT holds …

Contributions Of the Human Medial Prefrontal Cortex To Associative Recognition Memory: Evidence From Functional Neuroimaging
<p>Neuroimaging studies of episodic memory, or memory of events from our personal past, have predominantly focused their attention on medial temporal lobe (MTL). There is growing acknowledgement however, from the cognitive neuroscience of memory literature, that regions outside the MTL can support …

Design, Construction, and Validation of Magnetic Particle Imaging Systems for Rodent, Primate, and Human Functional Neuroimaging
Non-invasive neuroimaging techniques, such as functional magnetic resonance imaging, enabled a paradigm shift in the way neuroscientists study the brain. With these techniques, different levels of brain function can be safely localized in humans, allowing the study of diseases. However, due to the …

From Acute Injury to Chronic Disease: Exploring the Neurological Consequences of Mild Traumatic Brain Injury through Functional Neuroimaging
… and long-term disease, using multiple neuroimaging methods to better understand and prognosticate the outcomes of these individuals. Using data from collaborative multi-centre project CENTER-TBI, Chapters 2-5 explore the acute and enduring neurological effects after even the ‘mildest’ …

New approaches to diagnostic imaging: Magnetic particle imaging for human functional neuroimaging and short mid-field MRI magnet design
Part I: Magnetic Particle Imaging for Human Functional Neuroimaging While Magnetic Resonance Imaging (MRI) has revolutionized diagnostic imaging since its clinical introduction in the 1980s — primarily focusing on hydrogen nuclei — it remains fundamentally limited by the weak nature of nuclear spin …

Where Does it Stem From? - Functional Neuroimaging of Monoaminergic Brainstem Nuclei in Altered States of Consciousness: Translational, Diagnostic and Therapeutic Implications
… Indeed, the study of ASCs through human functional neuroimaging has identified large-scale cortical networks (such as the default mode network; DMN) whose disintegration is common across both pharmacological transient and pathological chronic ASCs. However, these cortico-centric network …

Exploring Neuroimaging-Specific Deep Learning Biases: Uncertainty, Dynamic Graphs, and Communities
… advancements have introduced non-invasive functional neuroimaging techniques, offering unparalleled insights into neural activity. Diverse imaging modalities, from electroencephalography's measurement of electrical signals to functional magnetic resonance imaging's visualisation of blood …

Functional Magnetic Resonance Imaging as an Assessment Tool in Critically Ill Patients
… this dissertation was to elucidate the role of functional neuroimaging in assessing brain activity in critically ill patients. The overall objective was addressed in the following four empirical chapters: In Chapter 2, three versions of a hierarchically-designed auditory task were developed and …

Classification of whole brain fMRI activation patterns
Functional magnetic resonance imaging (fMRI) is an imaging technology which is primarily used to perform brain activation studies by measuring neural activity in the brain. It is an interesting question whether patterns of activity in the brain as measured by fMRI can be used to predict the …

The Impact of Motivation on Object-Based Visual Attention Indexed by Continuous Flash Suppression.
… Using an interocular suppression technique and functional neuroimaging, this work has the ultimate aim of understanding how motivation impacts visual perception. In Chapter 2a, we demonstrate that novel objects with a more rich reward history are prioritized in awareness more quickly than …

Resting-state and task functional magnetic resonance imaging correlates of early language development in temporal and frontal lobe
… fully understood. In this dissertation, I use functional neuroimaging to evaluate the changing laterality of the language network, focused on two nodes. Those two nodes are the inferior frontal gyrus (IFG), which is implicated in syntactic processing, and middle temporal gyrus (MTG), which is …

Cortical Cartography: Mapping Functional Areas Across the Human Brain with Resting State Functional Connectivity MRI
… systems of multiple interconnected “functional areas”. Each functional area possesses a unique combination of inputs, outputs, and internal structure, and is thought to make a distinct contribution to information processing. Thus, the study of each area's normal function, …

Bayesian population inference for effective connectivity
… (MAR) process is proposed to jointly model functional neuroimaging time series collected from multiple subjects, and to characterize the distribution of MAR coefficients across the population from which those subjects were drawn. Thus, model-based inference about the interaction between …

Functional Activation Patterns in Pediatric-Onset Multiple Selerosis: Does Physical Activity Play a Role in the Maintenance of Working Memory
… memory task, while participants underwent functional neuroimaging. Participants also completed a neuropsychological battery and structural imaging in a 3T scanner. Findings suggest that inefficient processing and/or compensatory recruitment occurs in cognitively-preserved POMS patients for …
