Brodmann area 7 is one of Brodmann's cytologically defined regions of the brain. It is involved in locating objects in space. It serves as a point of convergence between vision and proprioception to determine where objects are in relation to parts of the body.

[edit] Human

Brodmann area 7 is part of the parietal cortex in the human brain. Situated posterior to the primary somatosensory cortex (Brodmann areas 3, 1 and 2), and superior to visual cortices (Brodmann areas 17, 18 and 19), this region is believed to play a role in visuo-motor coordination (e.g., in reaching to grasp an object).

[edit] Guenon

Brodmann area 7 is a subdivision of the cytoarchitecturally defined parietal region of cerebral cortex. It occupies most of the parietal lobe excluding the postcentral gyrus and superior parietal lobule. Brodmann-1909 considered it topologically homologous to the combined superior parietal area 7, the supramarginal area 40 (H) and the angular area 39 (H) of the human. Cytoarchitecurally he regarded it as "a still undifferentiated precursor zone for all parietal areas (apart from area 5)" (Garey-1999). Distinctive features (Brodmann-1905): in area 7 compared to Brodmann area 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.
