[The cytoarchitectonic characteristics of the speech center of the brain in gifted people in the plan to study individual variability of human brain structure].

Cytoarchitectonics of cerebral cortical fields 44 and 45 was studied in gifted people in comparison with the group of people without creative professional talents. Frontal paraffin sections 20 mkm thick were examined. Both histological and modern quantitative methods were used with the aid of "Videoplan" computer. Peculiarities in the cytoarchitectonics of cortical fields 44 and 45 and, in particular, in expression of the nerve cell horizontal and vertical orientation and in the characteristics of the certain cortical fields delimination were demonstrated. Increase of pyramidal neuron glial index and of peculiarities of neurons regrouping in cytoarchitectonic layers III and IV was noted.
