Behavioral Flexibility in Autism Spectrum Disorder: The Role of Memory and Its Neural Correlates
Cook, Kevin Michael (Georgetown University, 2020)Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder marked by social and behavioral deficits, including pronounced inflexibility. Behavioral interventions often fail to generalize, possibly due to difficulties ... -
DOPAMINE-REGULATING GENES, EXECUTIVE CONTROL, AND THE NETWORK STRUCTURE OF THE HUMAN BRAIN
Gordon, Evan Moss (Georgetown University, 2013)Executive control processes, including working memory (WM), attention, and impulse control, rely on brain networks centered in the prefrontal cortex, and especially on dopaminergic signaling in these networks. The function ... -
Establishing the sensitivity of functional near-infrared spectroscopy to cognitive load and state in healthy adults and children with Autism Spectrum Disorder
Fishburn, Frank Anthony (Georgetown University, 2017)Functional near-infrared spectroscopy (fNIRS) is an emerging low-cost noninvasive neuroimaging technique that measures cortical blood flow. While fNIRS has gained interest as a potential alternative to fMRI for use with ... -
Interaction of Attention and Emotion Across Development and Disorder
Ruiz, Ericka del Rocio (Georgetown University, 2012)This dissertation examines how attention and emotion interact in early visual processing across typical development and in Attention Deficit/Hyperactivity Disorder (ADHD). To investigate early visual processing, we utilized ... -
Multimodal Evidence for Neurocognitive Alterations in Pediatric Obesity
Rajan, Laya (Georgetown University, 2021)Pediatric obesity is increasing in prevalence and severity in the United States, with one in five adolescents meeting criteria for overweight (body mass index; BMI for age and sex >85th percentile) and one in three meeting ... -
Noradrenergic modulation of functional brain networks underlying executive control
Breeden, Andrew (Georgetown University, 2016)Executive control, the goal directed deployment of cognitive resources, depends critically on a class of neurotransmitters called catecholamines. One such catecholamine, norepinephrine, is theorized to facilitate cognition ...
