Abstract
The dynamics of electroencephalographic (EEG) parameters in adults were studied during active relaxation (which involved simple psychological techniques) and passive relaxation (without using any techniques). The experiment included four stages: background 1, active relaxation, passive relaxation, and background 2. During the experiment, the EEG was recorded in the occipital, parietal-temporal-occipital, central, and frontal regions of both hemispheres of the brain. Comparative analysis of the dynamics of EEG parameters during changing experimental conditions was performed in the frequency range from 5 to 40 Hz divided into ten frequency subranges. It was possible to establish the general pattern in the dynamics of EEG parameters at different relaxation stages, as well as differences in system-level brain performance in the active and passive relaxation states.
