Abstract: | Individual and age-related characteristics of visual perception as a whole and its individual components were studied in seven-year-old children as related to their brain functional development. A dependence was found between the success of visual perception and the characteristics determining the functional maturity of both the cerebral cortex and the brain regulatory structures. Difficulties in noise resistance, visuospatial perception, and visual analysis/synthesis were greater in first-year school students with signs of immaturity of the bioelectrical activity of the cerebral cortex. Poor development of the visual perception system in schoolchildren was also determined by an underdeveloped frontothalamic regulatory system and deviations in the functional state of the nonspecific activation system. |
