Cytoarchitectonic Characteristics of the Speech Motor Fields of the Cortex in Men and Women
The cytoarchitectonics of the speech motor cortical fields 44 and 45 in the left and right hemispheres were studied in men and women. Serial frontal sections stained with cresyl violet by the Nissl method were examined. The areas of neuron profiles were measured in layer III, along with its thickness and the crosssectional thickness of the cortex. There were no significant differences in these parameters between men and women. However, there were tendencies to larger values in men than in women in the left hemisphere of the brain and in women than in men in the right hemisphere.
