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 (RC2-3),
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 RC2-3,
MK, SC, CIP, also latency and an increase in amplitude the evoked
potential (ЕP). In
children was invented simultaneous activation of the early (N1, Р1, N2, Р2) and
deactivation of late (Р3) ЕP of the cerebral cortex and significant more mistakes and
lower speed of RC2-3, MC,
SC, CIP which
indicates the presence of
cortical-subcortical dysfunction of the sensor-motor system. In young people high
speed of RC2-3, MC,
SC, CIP
and a smaller quantities of
mistakes coincided with short latencies and a high amplitude of inter- peak intervals N1-P2
and P2-N2 and Р300. The results testify the formation of neurophysiological mechanisms of
sensory-motor differentiation reactions happens with participation,
mainly, of the early (N1, P1, N2, P2) components of children
whereas late components
of the ЕP (P3) are more actively involved in young people.
