Brodmann area 46

From Psychology Wiki

Brodmann area 46, or BA46, is part of the frontal cortex in the human brain. It is sandwiched between BA10 and BA45.

This area is known as middle frontal area 46. In the human it occupies approximately the middle third of the middle frontal gyrus and the most rostral portion of the inferior frontal gyrus. Cytoarchitecturally it is bounded dorsally by the granular frontal area 9, rostroventrally by the frontopolar area 10 and caudally by the triangular area 45 (Brodmann-1909).

[edit] Function

It is believed to play a role in memory retrieval.
