Structural Organization of the Motor Speech Area of an Outstanding Writer.

The current study is concerned with the macroscopic and cytoarchitectonic structure of the motor speech area 44 in the left and right hemispheres of the brain of an outstanding writer (age 62 years). In a series of 20-µm frontal total paraffin sections stained with cresyl violet by the Nissl method, the density of total glia, the density of satellite glia, and the density of neurons surrounded by satellite glia were analyzed. The motor speech area of the cortex of the famous writer is characterized by a more complex macroscopic and cytoarchitectonic structure. In Broca's area, the density of total glia, satellite glia, and the neurons surrounded by satellite glia in associative layer III of area 44 were higher than in the control (brains of 5 men aged 59-71 years).
