The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker
The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker
Dissertations & Theses (Open Access)
Adolescence is a dynamic period of social, cognitive, and biological changes. In particular, working memory, the ability to actively encode and maintain information over a short period of time, develops early in childhood and gradually increases in capacity and stability during adolescence. The precise neurophysiological mechanism by which working memory capacity increases during adolescence is unclear. The objective of this investigation was to evaluate the role of cortical gamma-band (> 30 Hz) oscillations—which are associated with working memory in adults—for the development of working memory capacity in adolescents, and to identify the extent to which the temporal profile of gamma-aminobutyric …
The Effects Of Acute Aerobic Exercise And Caffeine On Working Memory And Caffeine Withdrawal, Anisa Morava
The Effects Of Acute Aerobic Exercise And Caffeine On Working Memory And Caffeine Withdrawal, Anisa Morava
Electronic Thesis and Dissertation Repository
Caffeine is one of the most widely used psychoactive substances worldwide. Although caffeine elicits cognitive benefits, there are concerns regarding caffeine’s effects on certain health domains. Acute, aerobic exercise has been shown to improve cognition. The effects of aerobic exercise in comparison to caffeine on working memory (WM) in non-caffeine and caffeine consumers remains unknown. Furthermore, the effects of aerobic exercise in reducing caffeine withdrawal symptoms has yet to be examined. In Phase I, twenty-nine non-caffeine and thirty caffeine consumers completed a WM assessment, followed by aerobic exercise and caffeine administration (counterbalanced). In Phase II, twenty-five caffeine consumers underwent a …
