Prefrontal cortex of the brain of men and women in old age

The study was carried out on a series of frontal total paraffin sections with a thickness of 20 m, colored with cresyl violet by the Nissl method. The cytoarchitectonic of the cortex of the area 10 of the prefrontal cortex of the frontal region of the brain of men (10 hemispheres) and the brain of women (10 hemispheres) in old age was studied. Modern morphometric methods were used in the work. As a result of the study, sex differences in age-related changes in the leading cytoarchitectonic characteristics of the cortex of the 10th frontal region of the brain of men and women were revealed. It is established that the thickness of the cortex of the area 10, the thickness of the associative layer III, the area of the profile field of the neurons of this layer in old age when compared with the elderly varies more in men than in women.
