title: [Morphological criteria of the individual variability of the human brain].
abstract: Structural organization of the layers III and V in the cortical fields (speech area, motoring, frontal inferior parietal) of the cerebral hemispheres and the nucleus caudatus have been quantitatively studied in 4 human beings. By means of a computer, area of profile fields of neurons, total volume of all the neurons and glyocytes in the histological section (total volumetric fraction of the neurons and glia) have been calculated, as well as percentage of the neurons having various size. The material is statistically treated. Certain morphological criteria of individual peculiarities have been established in the structural organization of the cortical and subcortical formations in the human brain. Individual variants in the value of the total volumetric fraction of the neurons and glia have been revealed, as well as peculiarities in composition percent of neuronal cells in the layers III and V. Differences in the area indices of the profile fields in separate persons and in various structures have been ascertained.
