Preferred Label : Brodmann (1909) area 46;
Uberon definition : Brodmann area 46, or BA46, is part of the frontal cortex in the human brain. It is
between BA10 and BA45. BA46 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. Brodmann area 46 roughly corresponds with the dorsolateral
prefrontal cortex (DLPFC), although the borders of area 46 are based on cytoarchitecture
rather than function. The DLPFC also encompasses part of granular frontal area 9,
directly adjacent on the dorsal surface of the cortex. Cytoarchitecturally, BA46 is
bounded dorsally by the granular frontal area 9, rostroventrally by the frontopolar
area 10 and caudally by the triangular area 45 (Brodmann-1909). There is some discrepancy
between the extent of BA8 (Brodmann-1905) and the same area as described by Walker
(1940);
