1This cluster extends medially to include the precuneus and caudally to include the superior occipital gyrus; it includes the most dorsal part of the inferior parietal lobule.
2This cluster extends rostrally to include the supplementary motor area, caudally to include the precentral gyrus, and medially to include the insula.
3This cluster extends rostrally to include the supplementary motor area, caudally to include the precentral gyrus, and ventrally to include the inferior frontal gyrus.
4This cluster extends caudally in the right hemisphere to include the dorsal cingulate cortex.
5This cluster covers part of the insula.
