Brodmann area 45, or BA45, is part of the frontal cortex in the human brain. Situated on the lateral surface, inferior to BA9 and adjacent to BA46. Together with BA 44 it comprises Broca's area a region which is involved in speech production.
This area is also known as triangular area 45. In the human, it occupies the triangular part of inferior frontal gyrus (H) and, surrounding the anterior horizontal limb of lateral sulcus (H), a portion of the orbital part of inferior frontal gyrus (H). Bounded caudally by the anterior ascending limb of lateral sulcus (H), it borders on the insula in the depth of the lateral sulcus. Cytoarchitectonically it is bounded caudally by the opercular area 44, rostrodorsally by the middle frontal area 46 and ventrally by the orbital area 47 (Brodmann-1909).
