Emotional food-cue-reactivity in anorexia nervosa and bulimia nervosa: An electroencephalography study.

ABSTRACT:

Objective

Food-cue-reactivity entails neural and experiential responses to the sight and smell of attractive foods. Negative emotions can modulate such cue-reactivity and this might be central to the balance between restrictive versus bulimic symptomatology in Anorexia Nervosa (AN) and Bulimia Nervosa (BN).
