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.
ExternallySourcedDefinition The term area 19 of Brodmann-1909 refers t The term area 19 of Brodmann-1909 refers to a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. It is cytoarchitecturally homologous to the peristriate area 19 of the human (Brodmann-1909). Distinctive features (Brodmann-1905): Compared to area 18 of Brodmann-1909, the pyramidal cells of sublayer 3b of the external pyramidal layer (III) are not as densely distributed, the layer is not as narrow, and its boundary with the internal granular layer (IV) is not as distinct; the cells in sublayer 3b are concentrated at its outer boundary leaving a narrow clear zone with no large pyramidal cells adjacent to layer IV; the granule cells of layer IV are less densely distributed and are intermixed with larger polymorphic cells so that, while the layer is still quite dark and prominent, it is somewhat widened and not as self-contained; the internal pyramidal layer (V) is characterized by large pyramidal ganglion cells, most in small groups, a pattern not seen in area 18; the cells in the multiform layer (VI) are clearly larger than in area 18; overall area 19 is somewhat thicker and less densely populated than area 18. r and less densely populated than area 18.
