State the term - Neuroanatomists Broadmann

Neuroanatomists Broadmann used a combination of staining and microscopy to map the cytoarcitecture (cell structure\type) of human cerebral cortex. His research lead him to the realisation that different cortical locations comprised structurally distinct types, and his map identified 52 numbered regions, many of which are still used for identification purposes today (Broadmann, 1909). The primary visual cortex is, for example, also known as area 17, and Broca's area straddles Brodmann's areas 44 and 45 in the left hemisphere.
