Brodmann area 31, also known as dorsal posterior cingulate area 31, is a subdivision of the
cytoarchitecturally defined cingulate region of the
cerebral cortex
The cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. It is the largest site of Neuron, neural integration in the central nervous system, and plays ...
.
In the human, it occupies portions of the
posterior cingulate gyrus and medial aspect of the
parietal lobe
The parietal lobe is one of the four Lobes of the brain, major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus.
The parietal lobe integra ...
. Approximate boundaries are the
cingulate sulcus
The cingulate cortex is a part of the brain situated in the medial aspect of the cerebral cortex. The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the cin ...
dorsally and the
parieto-occipital sulcus
In neuroanatomy, the parieto-occipital sulcus (also called the parieto-occipital fissure) is a deep sulcus in the cerebral cortex that marks the boundary between the cuneus and precuneus, and also between the parietal and occipital lobes. Only ...
caudally. It partially surrounds the
subparietal sulcus
In neuroanatomy, the subparietal sulcus () or suprasplenial sulcus is a sulcus, or crevice, on the medial surface of each cerebral hemisphere, above the splenium of the corpus callosum. It separates the precuneus from the posterior part of the ...
, 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).

A Brodmann area is a region of the cerebral cortex, in the human or other primate brain, defined by its cytoarchitecture, or histological structure and organization of cells. The concept was first introduced by the German anatomist Korbinian B ...
