Brodmannarea 39, or BA39, is part of the parietal cortex in the human brain.
BA39 encompasses the angular gyrus, lying near to the junction of temporal, occipital and parietal lobes.
Cytoarchitecturally it is bounded rostrally by the supramarginal area 40 (H), dorsally and caudally by the peristriate area 19, and ventrally by the occipitotemporal area37 (H) (Brodmann-1909).
Situated posterior to the primary somatosensory cortex (Brodmannareas 1, 2 and 3), and superior to visual cortices (Brodmannareas 17, 18 and 19), this region is believed to play in visuo-motor coordination (e.g., in reaching to grasp an object).
Brodmannarea 7 is a subdivision of the cytoarchitecturally defined parietal region of cerebral cortex in the guenon.
Distinctive features (Brodmann-1905): in area 7 compared to Brodmannarea 5-1909, large ganglion cells are absent from the internal pyramidal layer (V); the pyramidal cells of the external pyramidal layer (III) sublayer 3b are, on average, larger; the multiform layer (VI) is denser and narrower and more sharply bounded by subcortical white matter.
