The term area 44 of Brodmann (44) refers to a subdivision of the cytoarchitecturally defined frontal region of cerebral cortex (CTX) . In the human it corresponds approximately to the opercular part of the inferior frontal gyrus (OPRfr). It is bounded caudally by the inferior precentral sulcus (iprs) and rostrally by the anterior ascending limb of the lateral fissure (ltfaa). It surrounds the diagonal limb of the lateral fissure (ltfdg). In the depth of the ltf it is separated from the insul (INS) by the superior limiting sulcus (slms). Cytoarchitectonically it is bounded caudally and dorsally by area 6 of Brodmann (human), dorsally by the area 9 of Brodmann (human) and rostrally by the area 45 of Brodmann ( Brodmann-1909 ).
