An FMRI study of self-regulatory control and conflict resolution in adolescents with bulimia nervosa.

ABSTRACT:

Objective

The authors examined functional activity in the frontostriatal systems that mediate self-regulatory capacities and conflict resolution in adolescents with bulimia nervosa.

Method

Functional magnetic resonance imaging was used to compare blood-oxygen-level-dependent response in 18 female adolescents with bulimia nervosa and 18 healthy female age-matched subjects during performance on a Simon spatial incompatibility task. Bayesian analyses were used to compare the two groups on patterns of brain activation during correct responses to conflict stimuli and to explore the effects of antecedent stimulus context on group differences in self-regulation and conflict resolution.

Results

Adolescents with and without bulimia nervosa performed similarly on the task. Duri
