Fig. 1.

(a) Representative axial slices and cumulative midsagittal views of the standard Montreal Neurological Institute brain showing the extent of lesion overlap in the vmPFC patients. The white horizontal lines on the sagittal view are the positions of the axial slices, and the red numbers below the axial views are the x coordinates of each slice. The colour bar indicates the number of overlapping lesions. Maximal overlap occurred in BA 10, 11 and 32. The left hemisphere is on the left side. (b) Extent and overlap of brain lesions for the control patients. The figure represents the patients’ lesions projected on the same six axial slices of the standard Montreal Neurological Institute brain as shown in (a) above. Maximal overlap occurred in BA’s 17–19, 37. BA, Brodmann areas; vmPFC, ventromedial prefrontal cortex.
