[The dynamic and regional characteristics of the high-resolution EEG structure in voluntary activity]

For revealing the dynamics of interrelations between EEG components having stable tuning to individually determined frequencies a dynamical high resolution EEG structure analysis was used. There were three successive experimental stages: rest, motor reproduction of time interval and tapping. Significant increase of EEG components intercorrelations for the right frontal area, minimal number of significant relationships between EEG and movement temporal characteristics, and the occurrence of hemispheric asymmetry in the number of EEG-movement correlations were observed for time reproduction task. This task specifics and the possibilities of used approach for precise functional states differentiation are discussed.
