What is the neurobiology of anorexia nervosa?
In anorexia nervosa, severely restricted food intake appears to be related to overactive inhibitory control in combination with underactive reward circuitry. In contrast, dysregulation of both inhibitory and reward drives may manifest in the alternating over- and under-consumption characteristic of bulimia nervosa.
