Recent works have suggested an association between the ventromedial prefrontal cortex (VMPC) and social cognition or decision making. The aim of this study is to investigate the theory of mind and decision making in patients with VMPC lesions and in those with dorsolateral prefrontal cortex (DLPC) lesions. Patients with VMPC lesions (n=16) and those with DLPC lesions (n=14) were compared with healthy controls (HC) on faux pas recognition and 2 decision-making tasks. Consistent with previous data, patients with VMPC lesions performed worse on the theory of mind and decision making. Patients with DLPC lesions showed impairments of the theory of mind but performed at control levels on the 2 decision-making tasks. The results supported the view that a separation of function of 2 distinct subregions of the prefrontal cortex is important to the theory of mind and decision making.
