  1. BRAIN REWARD RESPONSE MAY IMPACT ANOREXIANERVOSA A new study has found that the brain’s response to taste stimuli is linked to high anxiety and a drive for thinness that could play a role in driving anorexia nervosa. The researchers, led by Dr. Guido Frank, MD, associate professor neuroscience at the University Of Colorado School Of Medicine, monitored a large group of patients with anorexia nervosa as they tasted sugar during brain imaging. of psychiatry and Frank found that as these patients restricted their diet, a brain reward circuit associated
