Brodmann area 39

Jump to: navigation, search

Brodmann area 39, or BA39, is part of the parietalcortex in the human brain. BA39 encompasses the angular gyrus, lying near to the junction of temporal, occipital and parietal lobes.

This area is also known as angular area 39 (H). It corresponds to the angular gyrus surrounding the caudal tip of the superior temporal sulcus. Dorsally it is bounded approximately by the intraparietal sulcus. Cytoarchitecturally it is bounded rostrally by the supramarginal area 40 (H), dorsally and caudally by the peristriate area 19, and ventrally by the occipitotemporal area 37 (H) (Brodmann-1909).

Brodmann area 39 plays a role in semantic aphasia. It was regarded by Alexander Luria as a part of the temporo-parieto-occipital area, which includes Brodmann area 40, Brodmann area 19, and Brodmann area 37.
