Exploring The Effects Of Depression And Physical Activity On Pattern Separation Performance, Michelle I. Nash
Exploring The Effects Of Depression And Physical Activity On Pattern Separation Performance, Michelle I. Nash
Theses and Dissertations
Cognitive performance declines in depression and increases with physical activity. These changes may in part be due to changes in the level of neurogenesis (the generation and survival of adult-born neurons), which decreases with depression and increases with physical activity. Pattern separation (the formation of distinct neural representations of incoming information through orthogonalizing similar patterns of activation) has also been linked to neurogenesis. This project explores pattern separation within these two populations through three experiments.Experiment 1. Previous research has found impaired pattern separation among individuals with higher depression scores, but who have not been diagnosed with Major Depressive Disorder (MDD). …
Imaging And Behavioral Correlates Of The Anterior Cingulate In Pediatric Traumatic Brain Injury, Tricia L. Merkley
Imaging And Behavioral Correlates Of The Anterior Cingulate In Pediatric Traumatic Brain Injury, Tricia L. Merkley
Theses and Dissertations
The anterior cingulate has been implicated in a number of cognitive processes that are at risk following traumatic brain injury (TBI), such as executive function and emotional processing. While the cingulate is believed to play a role in the above-mentioned cognitive processes, the relative roles of gray and white matter in functional outcomes post-TBI are not fully understood. The current study investigated various quantifiable brain properties (e.g., cortical thickness and volume, volume of underlying white matter, and white matter integrity) of the caudal anterior cingulate (CAC) gyrus and their relationships with behavioral measures of cognitive control following pediatric TBI.
