Area 31 - Dorsal Posterior cingulate cortex

The dorsal posterior cingulate area 31 is a subdivision of the cytoarchitecturally defined cingulate region of the cerebral cortex. In the human it occupies portions of the posterior cingulate gyrus and medial aspect of the parietal lobe. Approximate boundaries are the cingulate sulcus dorsally and the parieto-occipital sulcus caudally. It partially surrounds the subparietal sulcus, the ventral continuation of the cingulate sulcus in the parietal lobe. Cytoarchitecturally it is bounded rostrally by the ventral anterior cingulate area 24, ventrally by the ventral posterior cingulate area 23, dorsally by the gigantopyramidal area 4 and preparietal area 5 and caudally by the superior parietal area 7 (H) (Brodmann-1909).
