The Brain of an Outstanding Scientist-Inventor: Structural Organization of Area 10 of the Frontal Cortex.

We studied structural organization of cortical area 10 of the prefrontal cortex in the left and right hemispheres of the brain of an outstanding scientist and inventor (age 78 years). To this end, continuous series of 20-μm Nissl-stained frontal slices were compared with cortex sections of the same area from senile men (control group). It was found that the cytoarchitectonic organization of the cortical area 10 of the prefrontal cortex of the brain of an outstanding scientist-inventor is characterized by more pronounced vertical striation, greater thickness of the cortex and association layer III, higher density and size of pyramid neurons and higher density of satellite glia.
