Lutsyuk N. Electrophysiological analysis of attention development in children with a help of electroencephalographic biofeedback

The thesis is devoted to study of correlation between parameters of event-related potentials, EEG and characteristics of voluntary attention in healthy children for revelation of the children with poor level of attention development and its development by using EEG-biofeedback method. It is revealed that children with optimal characteristics of attention have maximum values of amplitudes of the following waves: Р2, P300, CNV, minimal values of amplitude of N2 component and minimal latent periods of P1-N1-P2 wave complex. Found out that children of 12-13 years of age with a high level of attention development characterized by big values of relation of power of beta1-rhythm to teta-rhythm, low beta-rhythm to teta-rhythm. Changes of the power spectrum of the rhythms are revealed as a result of carrying out biofeedback sessions. Registered changes are accompained by the improvments of some parameters of voluntary attention.
