Dr. Cox is interested in the physiological controls of food intake and body weight. His animal research has examined effects of gastrointestinal signals, such as the hormones cholecystokinin and peptide YY. The image to the left is an example of an area postrema lesion from a rat that was used in the first study cited below. His studies with obese and normal-weight human participants, done in collaboration with Drs. Rosalyn Weller and Edwin Cook, are using functional magnetic resonance imaging (fMRI) to investigate brain systems involved in responses to food cues and in decision making.
