[Characteristics of the functional organization of neuronal groups in functionally diverse zones of the human cerebral cortex from birth to 20 years of age].
Using computer analysis of histological specimens of motor and posterior associative cortex of the man aged from birth up to 20 yrs age and individual peculiarities of focal groups sublayer III3 of areas 4p, 6op and 37ac, periods of intensive and slow growth of the area of profile fields (PF) of cell groups and total area (TA) of neurons in the group were established. It was shown that greater changes of cell groups PF area and neuron TA occurred in the area 4p during first 3 yrs, while in areas 6op and 37ac from birth up to 7 yrs and 8-9 yrs appropriately. Specific features of the group development in functionally different areas of human brain cortex was demonstrated.
