Abstract

Cerebral cortex cytoarchitecture of speech-motor areas 44 and 45 in the left and right hemispheres of brain of men and women has been studied. Series of frontal sections stained with cresyl violet using Nissl's method have been investigated. In layer III, the surface of profile area of neurons, its width and the width of the whole cortex diameter have been measured. No significant differences of these values between men and women were detected. However, there was a clear tendency of increased values of these parameters in the left hemisphere in men, as compared with women, while women had highest values in the right hemisphere.
