[Sex dimorphism of neuron-glia correlations in the frontal areas of the human brain].
In the series of frontal 20 microm thick paraffin sections, stained using Nissl's cresyl violet method, frontal areas 8, 10, 12, 47 were studied. The important parameters of neuronal functional and metabolic activity--total density of pyramidal neuron distribution (N), the density of satellite gliocyte distribution (SG), the density of the distribution of the neurons, surrounded by satellite glia (NS) as well as the neuron-glia index (NS/N)--were calculated in the cortical layers III and V, areas 8, 10, 12, 47 in both left and right hemispheres in 0.001 mm3 of brain substance. It was found that in women the parameters studied (SG, NS and NS/N) were higher in the cortical areas 12, 47, 10 as compared to those in men, and were lower in area 8. It is concluded that in women, cortical neurons had higher functional and metabolic activity in the areas, associated with emotions, will and intellectual activity while in men they were higher in the areas involved in motor activity.
