Associations Between Children's Perceptions Of Interparental Conflict And Neuropsychological Correlates Of Interpersonal Emotion Stimuli, Hannah C. Woolfolk
Associations Between Children's Perceptions Of Interparental Conflict And Neuropsychological Correlates Of Interpersonal Emotion Stimuli, Hannah C. Woolfolk
Graduate College Dissertations and Theses
Exposure to interparental conflict has been implicated in children's development. Research suggests that underlying mechanisms, such as neuropsychological indicators of cognitive processes, may shed light on how exposure to interparental conflict differentially influences children's outcomes over time. Event-related potentials (ERP), extracted from electroencephalogram data, allow for examination of neuropsychological markers of cognition based on precise timing and scalp topography of electrical activity in the brain. For example, the late positive potential (LPP) ERP component has been implicated in the timing and magnitude of sustained attention and emotion regulation processes elicited in response to emotionally salient stimuli. LPP amplitudes and peak …
Intra-Bed Nucleus Of The Stria Terminalis Pituitary Adenylate Cyclase-Activating Peptide Infusion Reinstates Cocaine Seeeking In Rats, Olivia Miles
Graduate College Dissertations and Theses
The tendency of users to relapse severely hinders adequate treatment of addiction. Physical and psychological stressors often contribute to difficulties in maintaining behavior change, and may play a significant role in relapse. We have previously shown that the activation of pituitary adenylate cyclase activating peptide (PACAP) systems in the bed nucleus of the stria terminalis (BNST) mediates many consequences of chronic stressor exposure. Hence, chronic stress substantially increased BNST PACAP levels, intra-BNST PACAP infusions produced the behavioral and endocrine consequences of stressor exposure, and BNST PACAP antagonism blocked many of the consequences of chronic stress. In the present set of …
Learning Related Regulation Of A Voltage-Gated Ion Channel In The Cerebellum, Jason R. Fuchs
Learning Related Regulation Of A Voltage-Gated Ion Channel In The Cerebellum, Jason R. Fuchs
Graduate College Dissertations and Theses
The neural mechanisms that support learning and memory are still poorly understood. Much work has focused on changes in neurotransmitter receptor expression, while changes in voltage-gated ion channel expression have been largely unexplored, despite the fact that voltage-gated ion channels govern neuronal excitability. Here we used eyeblink conditioning (EBC) in rats, a model of learning and memory with a well-understood neural circuit, to examine regulation of voltage-gated ion channels as a consequence of learning. EBC is a form of classical conditioning that involves pairings of a behaviorally neutral conditioned stimulus (CS) and an eyeblink eliciting unconditioned stimulus (US) over many …
