Abstract :The amplitude-frequency characteristics of the late and early components of brain- evoked potentials (EP) and the speed of motor (MK), central ( central information processing (CIP ) and sensory (SC) component of the reaction of choice 2 from 3 stimuli (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 ( Е P ) . In children was invented simultaneous activation of the early ( N 1 , Р 1 , N 2 , Р 2 ) and deactivation of late (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 (N 1 , P 1 , N 2 , P 2 ) component s of children whereas late components of the Е P (P 3 ) are more actively involved in young people .Keywords : Ontogenesis, paradigm go/nogo/gо
