[Morphologic criteria of the structural asymmetry of the cortical and subcortical structures of the human brain].
Using a cytoarchitectonic and quantitative methods, the authors investigated the structural organization of Fields 4, 6, 8, 39, 40, 43, 46, 47, caudate and dorsomedial nuclei of the tuber cinereum in the right and the left cerebral hemispheres in a grown-up right-handed man. With the help of electron computers definite parameters of neurons in the cortex (layers III and V) and in the subcortical nuclei were determined. The material obtained was statistically processed. Morphological criteria of the structural organization of the above-listed formations were identified. These included indicators of the total volumetric fraction of neurons and glia, profile fields of neurons, and the neuronal composition. Structural asymmetry was revealed, with the left hemisphere being dominant in the logomotor and motor fields. There were no signs of structural asymmetry in either the frontal and parietal fields or in the subcortical formations. The interpretation of the results obtained is attempted.
