  • Externally Sourced Definition: The term area 18 of Brodmann-1909 refers to a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. It is topographically and cytoarchitecturally homologous to parastriate area 18 of the human (Brodmann-1909). Distinctive features (Brodmann-1905): a wide, dense internal granular cell layer (IV); a distinct sublayer 3b of closely packed large pyramidal cells positioned in the external pyramidal layer (III) directly above layer IV; an almost cell free, narrow internal pyramidal layer (V) with no larger ganglion cells; a likewise very narrow, dense multiform layer (VI) composed of small polymorphic cells that form a distinct boundary with the underlying subcortical white matter. Like area 17 of Brodmann-1905, area 18 is relatively thin; the three deep layers are thin relative to the three outer layers; distinct boundaries between layers; abundance of granule cells; narrow layer VI; and sharp boundary between cortex and subcortical white matter.

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.
