Brodmann areas

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.

Brodmann areas:
1, 2 & 3, 4, 5, 6,  7,  8,  9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41 & 42, 43, 44, 45, 46, 47 48, 49, 52
