A simultaneous positron emission tomography (PET)- functional magnetic resonance imaging (fMRI) approach and testing of food preferences and choices will provide further insight into the link between potential abnormalities in serotoninergic transmission and the specific food restriction disorder for Anorexia Nervosa. These Data can pave the way for new therapeutic avenues.
Serotoninergic activity in brain structures involved in food control and avoidance, such as the basal ganglia, is poorly understood in Anorexia Nervosa.
