Abstract

The article is devoted to the study of the structural organization of neural ensembles in the motor and visual regions of the cerebral cortex (26 observations) in children from 8 to 12 years old with the method of computer morphometry. The basic quality (form of nesting groups, the composition and the composition of its constituent groupings of pyramidal neurons) and quantitative parameters: width, height, area of the profile fields (APF) groups of neurons of III and IV layers of the fields 4p, 6, 6op of the motor cortex and fields 17, 19 of the visual cortex. Measurements were made using the “Armistol” interactive image analysis system (Labmetod) based on the Nikon Eclipse E-200 microscope and the CCD-camera color video camera. It is shown that the size, number, type and composition of neurons in nesting groups are different in different fields of the cerebral cortex. According to computer morphometry, a significant increase in the area of the profile fields of neural groupings occurs in the field 6p to 8 and 10 years, in the fields 4p and 6 - to 9 years, in the field 17 - to 10 and 12 years, in the field 19 - to 8 and 12 years.
