- Externally Sourced Definition: The term area 9 of Brodmann-1909 refers to a cytoarchitecturally defined portion of the frontal lobe of the guenon. Brodmann-1909 regarded it on the whole as topographically and cytoarchitecturally homologous to the granular frontal area 9 and frontopolar area 10 in the human. Distinctive features (Brodmann-1905): unlike area 6 of Brodmann-1909, area 9 has a distinct internal granular layer (IV); unlike area 6 or area 8 of Brodmann-1909 its internal pyramdal layer (V) is divisible into two sublayers, an outer layer 5a of densely distributed medium sized ganglion cells that partially merges with layer IV, and an inner, clearer, cell-poor layer 5b; the pyramidal cells of sublayer 3b of the external pyramidal layer (III) are smaller and sparser in distribution; the external granular layer (II) is narrow, with small numbers of sparsely distributed granule cells.

| 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. |
