Abstract :The amplitude-frequency characteristics of the late and early components of brain- evoked potentials insert ignore into journalissuearticles values(EP); and the speed of motor insert ignore into journalissuearticles values(MK);, central insert ignore into journalissuearticles values( central information processing insert ignore into journalissuearticles values(CIP ); and sensory insert ignore into journalissuearticles values(SC); component of the reaction of choice 2 from 3 stimuli insert ignore into journalissuearticles values(RC 2-3 );, presented in mode go/nogo/gо investigated in children, teenagers and young people. It was found that the formation of sensorimotor reactions of differentiation in children, teenagers and young people is characterized by a gradual decrease in the quantities of mistakes and time of RC 2-3 , MK, SC, CIP , also latency and an increase in amplitude the evoked potential insert ignore into journalissuearticles values( Е P ); . In children was invented simultaneous activation of the early insert ignore into journalissuearticles values( N 1 , Р 1 , N 2 , Р 2 ); and deactivation of late insert ignore into journalissuearticles values(Р 3 ); Е P of the cerebral cortex and significant more mistakes and lower speed of RC 2-3 , MC, SC, CIP which indicates the presence of cortical-subcortical dysfunction of the sensor-motor system. In young people high speed of RC 2-3 , MC, SC, CIP and a smaller quantities of mistakes coincided with short latencies and a high amplitude of inter- peak intervals N 1 -P 2 and P 2 -N 2 and Р 300 . The results testify the formation of neurophysiological mechanisms of sensory-motor differentiation reactions happens with participation , mainly, of the early insert ignore into journalissuearticles values(N 1 , P 1 , N 2 , P 2 ); component s of children whereas late components of the Е P insert ignore into journalissuearticles values(P 3 ); are more actively involved in young people .
