Locations of 6 VOIs defined on MR images used in SPECT-based discrimination tasks. (A) Banks of superior temporal sulcus (red). (B) Basal forebrain (orange) and amygdala (blue). (C) Rostral anterior cingulate gyrus (orange), caudal anterior cingulate gyrus (blue), and posterior cingulate gyrus (white).
