Neurobiological and neuroimaging studies have demonstrated that the ventral medial prefrontal cortex (vmPFC), a major node for decision making, is crucial in drug addiction. 1,2 However, little is known about the role of the vmPFC network and its relation to drug-seeking behaviors, such as impulsivity in addiction. In this study, we utilized resting-state functional connectivity fMRI (R-fMRI) to investigate the alteration of the vmPFC network and its relationship to impulsivity in abstinent heroin dependent subjects (HD) and control nondrug users (CN).
