Brodmann area 46
From Wikipedia, the free encyclopedia
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
Inasmuch as the Brodmann areas are distinct only based on cytoarchitecture, Brodmann area 46 is functionally part of a group known as the dorsolateral prefrontal cortex. For further information please consult the referenced article.
The DLPFC Roughly corresponds to Brodmann's area 46. There is some discrepancy between the exetent of Brodman's area 8 (1905) and the same area as described by Walker (1940)[1]
