Sugar Consumption Alters Perception Of And Response To Stress In Undergraduate Students: Understanding The "Freshmen Fifteen", Katherine M Keever
Honors Theses
Psychological stress is a common part in everyday life that directly affects the body through the nervous system and neuroendocrine hormones. A perceived stressor leads to the activation of the hypothalamic-pituitary-adrenal (HPA) axis, and the synthesis and release of the glucocorticoid hormone cortisol from the adrenal cortex. Studies have linked the release of cortisol during high-stress periods to an increased intake of sugary and fatty foods, consistent with a suspected glucocorticoid-metabolic-brain- negative pathway, with high sugar consumption leading to lower stress and subsequently cortisol levels. In this study, undergraduate students’ diets were supplemented with either a high sugar drink or …

The Effects Of Early Confidence Interval Training On User Efficacy In A P300 Brain-Computer Interface Spelling Task, Adam Starkman
Honors Theses
Brain-computer interface (BCI) technology can provide communication for individuals suffering from degenerative neuromuscular disorders. The present study sought to demonstrate improved BCI performance in healthy individuals using confidence interval training with a P300 BCI spelling program. In this BCI interface, electroencephalographic (EEG) activity was recorded as participants attended to a specific target character within a matrix of flashing letters and numbers presented on a computer screen. The BCI uses the P300 Event Related Potential to select the intended character. In a prior patient case, use of a confidence measure that rejected questionable selections improved that user’s spelling efficiency. The present …
