A Brodmann area is a region in the brain cortex defined in many different species based on its cytoarchitecture. Cytoarchitecture is the organization of the cortex as observed when a tissue is stained for nerve cells.

Brodmann areas were originally defined by Korbinian Brodmann and referred to by numbers from 1 to 52. Some of the original areas have been subdivided further and referred to, e.g., as "23a" and "23b". The same number in different species does not necessarily represent structurally homologous areas.

Criticism

When von Bonin and Bailey were to construct a brain map for the macaque monkey they found the description of Brodmann inadequate and wrote:

Brodmann (1907), it is true, prepared a map of the human brain which has been widely reproduced, but, unfortunately, the data on which it was based was never published[1]

They instead used the cytoarchitechtonic scheme of Economo and Koskinas published in 1925 which had the "only acceptable detailed description of the human cortex".
