Abstract Details

2010, Master of Arts, Case Western Reserve University, Psychology.
The etiology of obesity is yet to be fully understood. Neuroimaging studies have demonstrated that the central nervous system has a central role in regulating eating behavior. Functional magnetic resonance imaging was used to study the correlations between food related behaviors and the neuroanatomical sites underlying responses to visual food stimuli, before and after eating, in healthy weight individuals and mildly obese individuals. In healthy weight individuals, during fasting, activity in the left amygdala, left fusiform gyrus, and right parahippocampal gyrus were positively correlated with impaired satiety scores when presented with high calorie images vs. non-food images. Likewise, impaired satiety scores and food preoccupation scores were correlated with distinct brain regions in mildly obese individuals. Results suggest ROIs involved in the assessment of visual stimuli of food were found to correlate with ‘food preoccupation’ and ‘impaired satiety’ scores depended on calorie content, state of satiation, and BMI.
