The cytoarchitecture of area 39 of inferior parietal cortex region in the left and right cerebral hemispheres was studied in usual individuals and in professionally gifted world-famed people. The series of frontal sections, stained using Nissl cresyl violet method, were examined. The profile areas of neurons in cortical layers III and V were measured and their distributions were analyzed. In the group of gifted people, individual variability of the characteristics studied was found to be significantly increased, especially in the right cerebral hemisphere, while the relative content of both very small and very large neurons was elevated.
