Where is it?
Brodmann area 47, or BA47, is part of the frontalcortex in the human brain. Curving from the lateral surface of the frontal lobe into the ventral (orbital) frontal cortex. It is inferior to areas BA10 and BA45, and lateral to BA11. Jump to: navigation, search The frontal lobe is an area in the brain of vertebrates. ...

This area is also known as orbital area 47. In the human, on the orbital surface it surrounds the caudal portion of the orbital sulcus (H) from which it extends laterally into the orbital part of inferior frontal gyrus (H). Cytoarchitectonically it is bounded caudally by the triangular area 45, medially by the prefrontal area 11 of Brodmann-1909, and rostrally by the frontopolar area 10 (Brodmann-1909).
Brodmann assigned numbers to various brain regions by analyzing each area's cellular structure starting from the central sulcus [the boundary between the frontal and parietal lobes].
As you may notice, many of the areas that are involved in the same general cognitive functions are numbered sequentially (or almost).
Areas that perform the same tasks use essentially the same types of cells.
Cytoarchitecturally bounded rostrally by the preparietal area 5 and the caudal postcentral area 2; caudally by the peristriate area 19; and medially by the dorsal posterior cingulate area 31.
Cytoarchitecturally bounded dorsocaudally by the intermediate frontalarea 8, caudally by the agranular frontalarea 6, and ventrally by the frontopolar area 10, the middle frontalarea 46 and the opercular area 44.
Cytoarchitecturally bounded on the rostral and lateral aspects of the hemisphere by the frontopolar area 10, the orbital area47, and the triangular area 45; on the medial surface it is bounded dorsally by the area 12 and caudally by the subgenual area 25.
