Peak activations from neuroimaging studies of pain are found predominantly in the supracallosal cingulate cortex (blue squares). Many of the activations are in the ventral part of this region in cluster 7, but some fall in the more anterior cingulate sulcus in cluster 5. Cluster 5 may include the CMAr. Morrison and colleagues (Morrison and Downing, 2007; Morrison et al., 2007) have argued that rostral cingulate motor areas are also active when experimental participants are subjected to painful stimulation.
