- 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.

| EditorialNote | The 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. |
