title: [Age-related changes in the cytoarchitectonics of the human sensorimotor cortex].
abstract: The study of human brain sensomotor cortex architectonics within the period since birth up to 20 years with a year long intervals demonstrated that pyramidal neurons differentiation is most intensive in area 4p throughout the period since birth up to 6 months, in area 6p--up to one year and in area 6op--up to 2 years. Pyramidal neurons proportion in sublayer 3 increases significantly in all sensomotor cortex areas within the first postnatal year and its growth continues up to 15-16 years. In area 5 proportion of pyramidal neurons in areas studied undergoes the period of intensive growth up to one year, than it starts to increase by 6-7 years, and finishes its growth in areas 6 and 6op by 14 years and in area 4p--by 16 years.
