Brodmann area

Brodmann areas are the areas in the brain separated based on the cytoarchitecture organization of neurons observed by the German anatomist Korbinian Brodmann.

History
Brodmann areas were originally defined and numbered by the German anatomist Korbinian Brodmann based on the cytoarchitectural organization of neurons he observed in the cerebral cortex using the Nissl method of cell staining. Brodmann published his maps of cortical areas in humans, monkeys, and other species in 1909, along with many other findings and observations regarding the general cell types and laminar organization of the mammalian cortex. The same Brodmann area number in different species does not necessarily indicate homologous areas. A similar, but more detailed cortical map was published by Constantin von Economoand Georg N. Koskinas in 1925.
