Fig. 5. (A ) Brain area in which blood flow increases in proportion to pain sensation ratings, in the specific context of the hypnotic state: the ventral part of the midcingulate cortex (tentatively area 24′a). Results are displayed on the subject’s T1-weighted average magnetic resonance imaging scan, normalized to the same standardized space. (B ) Plot of adjusted anterior cingulate cortex blood flow versus pain perception ratings. The results show that there is a significant difference (P = 0.047, voxel level) in pain ratings versus regional cerebral blood flow regression slopes between the hypnotic state (green) and control conditions (red).
