Brodmann (1909) area 45

Name: Brodmann (1909) area 45
Description: Part of the cytoarchitecturally defined frontal region of cerebral cortex. In the human, it occupies the triangular part of the inferior frontal gyrus (human) and, surrounding the anterior horizontal limb of the lateral sulcus (human), a portion of the orbital part of the inferior frontal gyrus (human). Bounded caudally by the anterior ascending limb of the lateral sulcus (human), 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 area 46 of Brodmann (human) and ventrally by the area 47 of Brodmann (human) (Brodmann-1909) (Adapted from Brain Info)
Synonym(s): area 45 of Brodmann-1909, Brodmann area 45, Area triangularis, triangular, Brodmann.45
Abbreviation: B09-45, BA45
Is part of: Broca's area, Frontal cortex
Super-category: Brodmann partition scheme region

EditorialNoteThe lobular mapping of Brodmann areas has The lobular mapping of Brodmann areas has been adapted from the LOCATION hierarchy in Brainmap.org. To date (2007-10-02) this only define the set of lateralized cerebral lobe locations where a given Brodmann area is located. The intension is to eventually incorporate the more detailed gyri and sulci relations as well. detailed gyri and sulci relations as well.
