title: [Effect of motor activity of adolescents on visual evoked cortical potentials].
abstract: Light flashes, indifferent to the subject, of 5 msec duration and of 0.27 joule intensity, were presented during school period to two groups of children with different levels of motor activity. The school children whose mobility was by 40 to 45% below the physiological norm exhibited longer latencies of late P3 and O3 components of averaged visual evoked potentials. It is assumed that the longer latencies are due to a lowered level of functional activity of the non-specific brain structures working in conditions of hypokinesia in a more synchronized regime. The introduction of a daily lesson of physical exercises of enhanced motor activity suffices to compensate for disturbances in the brain integrative activity, caused by hypokinesia.
