Primary outcomePrimary: Brain Activation Associated With P(Stop) — 0.02; 0.11; 0.04; 0.05 BOLD Signal
Summary
This study examines the influence of acute fasting and eating on self-control in adult females with and without bulimia nervosa (BN). Specifically, the study team is investigating whether differences in behavior and brain activation in response to computer tasks after fasting and after eating a meal could help to explain the symptoms of bulimia nervosa. Data will be collected using questionnaires and a technology called magnetic resonance imaging (MRI).
