An fMRI investigation of the fronto-striatal learning system in women who exhibit eating disorder behaviors

► fMRI study of fronto-striatal learning system in eating disorder behaviors. ► Participants characterized as subthreshold bulimia (Sub-BN) category of EDNOS. ► Sub-BNs did not vary behaviorally from controls on probabilistic category learning. ► Sub- BNs showed increases in caudate nucleus and dorsolated prefrontal cortex. ► Sub-BNs showed distinct temporal pattern of fronto-striatal and MTL systems.
