Adiposity And Arterial Stiffness: Associations With Prefrontal Cortex Hemodynamic Response And Response Inhibition, John William Capps

Open Access Theses & Dissertations

Obesity is a global health crisis associated with increased arterial stiffness, diminished brain reactivity, and diminished executive functioning. Inhibitory control, a specific domain of executive functioning, is known to be especially important to behaviors influencing health. The current study aimed to determine if increased adiposity and arterial stiffness were associated with performance and brain activation for two inhibitory control subtypes, response restraint, and response cancellation. Carotid-femoral pulse wave velocity, the Cued Go/No-go Task, the Stop Signal Task, and functional Near-Infrared Spectroscopy (fNIRS) were used to investigate these relationships. Pearson correlations indicated that slower stop-signal reaction time was associated with a …
