Influence of the course of electrostimulation by the device "VEB-1" on parameters of electroencephalogramm at practically healthy males

Abstract

20 parameters of EEG were identified, in which the volunteers' neurodynamics before and after the course of electrostimulation differed considerably (Squared Mahalanobis Distance make up 191; F=16,7; p<10-3). The neurotropic stimulation effect has a modulating character, namely: the initially decreased spectral power density (SPD) of the alpha-rhythm in F3, F4, T4, T5 loci as well as of theta-rhythm in P3 locus increases; decreased SPD of beta-rhythm in the F3, C3, C4, P3, P4 and O2 loci as well as Amplitude of beta-rhythm becomes even smaller; the initially increased SPD of delta-rhythm in the loci Fp1, F8 and P4 rises further.
