Functional Brain Connectivity Estimators: Understanding and Developing New Methodologies
… are used for constructing a specific part of the brain functional networks (i.e., functional connectivity or the relationship between different parts of the functional networks). In addition, we will develop new methodologies for estimating functional connectivity and propose modifications for …

Effects of methamphetamine on prenatally exposed children in Cape Town: cognition and intrinsic functional brain connectivity
… exposure (PME) on cognition and the developing brain in a sample of affected children in Cape Town, South Africa. Thus, this is a two-part study: the first part examines the effects of PME on neuropsychological outcomes, and the second part examines the effects of PME on intrinsic functional …

Intrinsic functional brain connectivity in South African methamphetamine users undergoing inpatient treatment, with or without additional cognitive training
… suggests MA alters intrinsic resting state functional connectivity (rsFC), and this may contribute to neuropsychological deficits observed in methamphetamine use disorder (MUD). Methods: This nested study analysed data described in Brooks et al. (2016), in which WM training was used as an …

Fully Hyperbolic Graph Convolutional Neural Networks for Age Prediction with Multi-Modal Brain Data
Characterizing age-related alterations in MEG brain networks holds great promise in understanding aging trajectories and revealing aberrant patterns of neurodegenerative disorders, such as Alzheimer’s disease. In this study, we utilize a Fully Hyperbolic Neural Network (FHNN) to embed functional …

Functional Imaging the Neonatal Brain with Wearable Diffuse Optical Tomography
Studying brain development poses significant methodological challenges when working with vulnerable newborn infant populations. Non-invasive and wearable optical brain imaging technologies may allow for the cot-side study of newborn infants in clinical settings. This has particularly important …

Hyperbolic graph embedding of magnetoencephalography brain networks to study brain alterations in patients with subjective cognitive decline
Identifying subtle changes in brain activity in the early stages of pathology is crucial for gaining understanding of the causes and mechanisms of neurodegenerative diseases such as Alzheimer’s disease (AD). Mapping high dimensional brain connectivity information to a lower dimensional latent space …

The Association between the Immune Proteome and Brain Function and Socioemotional Development in 5-Year-Old Children
… a critical developmental period of rapid brain and socioemotional development. Despite growing evidence of immune processes in brain development, most research has focused on prenatal exposure or adult populations and has examined a limited number of classical inflammatory markers. …

Experience-Dependent and Input-Specific Regulation of Neocortical Circuit Development by Genes Linked to Neurodevelopmental Disorders
Abnormal structural and functional brain connectivity has been widely observed in human neuropsychiatric diseases. Specifically, patients with neurodevelopmental disorders like autism often show an imbalance in the local versus long-range connectivity for cerebral cortex. Whether and how genes …

Classification of 4D fMRI Images Using ML, Focusing on Computational and Memory Utilization Efficiency
… novel data reduction techniques in determining functional brain connectivity from Resting-State fMRI data and show that small Machine Leaning models can with good accuracy classify subjects with respect to Alzheimer’s disease (AD) or Mild Cognitive Impairment (MCI) or being Cognitive Normal …

Effect of Levodopa on EEG Connectivity in Parkinson's Patients
… recordings to determine how Levodopa affects the functional connectivity of their brain networks. We used several metrics from graph theory, in particular the minimum spanning tree (MST) metric, and analyzed how they change after subjects take Levodopa. We observed significant changes in the lower …

Revealing the plastic brain with functional connectivity: effects of exercise on brain plasticity and cognition
… about precisely how exercise effects on the brain benefit human cognition (Cotman and Berchtold, 2002; Kramer and Erickson, 2007). In this thesis I examine effects of physical activity on age-related deficits in brain function and cognition, followed by an examination of potential explanatory …
