Korbinian Brodmann divided the brain up in regions based on . A. the staining techniques that worked for the different regions of the cortex B. the structure of the cells in the different regions of the cortex C. both (a) and (b) D. neither (a) nor (b)

Option C.

Both a and B.

Explanation:

Korbinian Brodmann was a German neurologist who identified 52 regions of the cerebral cortex in the year 1909.

He divided the cerebral cortex into regions base on cytoarchitecture (cell size,space, Density, lamination, cell bodies) differences. He observed the area of cerebral cortex using Nissl cell staining method .
