Asp et al. Neural correlates of credulity surgical resection for treatment of a meningioma or seizure con- trol (n D 15), and focal contusions from trauma (n D 3). In con- nection with their enrollment in the Patient Registry, the brain damaged patients have been extensively characterized neuropsy- chologically and neuroanatomically, using standard protocols of the Benton Neuropsychology Laboratory and the Laboratory of Brain Imaging and Cognitive Neuroscience (Tranel, 2007). Eigh- teen patients had damage to the vmPFC and were classiﬁed into our vmPFC group (Figure 1); while 21 patients had lesions outside the prefrontal cortex and were classiﬁed into our brain damaged comparison group (BDC; Figure 2). Patients with prefrontal cor- tex damage to areas primarily outside the ventromedial regions were excluded from analysis. While other prefrontal areas are pre- dicted to have a role in “false tagging” it is beyond the scope of this study to address more speciﬁc relationships within the prefrontal cortices. All neuropsychological and neuroanatomical data were collected in the chronic phase of recovery, at least 3 months post-lesion onset. We also included a normal comparison group (n D 10) which was comprised by individuals of similar age and education to our patient groups. BDC patients were slightly FIGURE 1 | Lesion overlap of patients with ventromedial prefrontal cortex lesions. The overlap map shows the lesions of vmPFC patients displayed in anterior/mesial views and coronal slices (a–f, with the right hemisphere on the left in the coronal views). The color bar indicates the number of overlapping lesions per voxel. www.frontiersin.org July 2012 | Volume 6 | Article 100 | 3
