[The individual characteristics of the cytoarchitectonics of the human motor cortex (based on computer analysis data)].

Age and individual peculiarities of cytoarchitecture of layer III field 4p, periods of intensive and slow growth of the area of profile fields (APF) of pyramid neurons were established by method of computer analysis of histological preparations of human motor cortex from birth up to 20 yrs. It was shown that the greatest changes of APF of pyramid neurons including their individual parameters occur in field 4 of motor cortex during first three years.
