[The age-dependent dynamics of brain potentials related to movement in 9- to 12-year-old children].

[Article in Russian]

Abstract

Movement-related brain potentials (MRBP) were recorded from F3, F4, C3, C4, and Cz in 47 children aged 9-10 and 49 children aged 11-12 in simple button-push task. Difference in MRBP parameters between the two groups was revealed. Amplitude of readiness potential in the left frontal derivation was higher in the older group than in the younger one. In the right frontal and central regions the readiness potential had definitive characteristics in both age groups. Two subcomponents (P2a and P2b) of P2 postmovement positivity were found in both groups. The amplitude of P2b subcomponent and the latency of N3 component increased from 9-10 to 11-12 years.
