Preferred Label : Brodmann (1909) area 44;
Uberon definition : Brodmann area 44, or BA44, is part of the frontal cortex in the human brain. Situated
just anterior to premotor cortex and on the lateral surface, inferior to BA9. This
area is also known as pars opercularis (of the inferior frontal gyrus), and it refers
to a subdivision of the cytoarchitecturally defined frontal region of cerebral cortex.
In the human it corresponds approximately to the opercular part of inferior frontal
gyrus (H). Thus, it is bounded caudally by the inferior precentral sulcus (H) and
rostrally by the anterior ascending limb of lateral sulcus (H). It surrounds the diagonal
sulcus (H). In the depth of the lateral sulcus it borders on the insula. Cytoarchitectonically
it is bounded caudally and dorsally by the agranular frontal area 6, dorsally by the
granular frontal area 9 and rostrally by the triangular area 45 (Brodmann-1909).;
