EEG power spectra in simulation of disruptiveness

Abstract

For analysis of the action of destructive behavior, the EEG power spectra in groups with different levels of disruptiveness at rest and during the modeling of destructive behavior were studied. The destructive processes in the group of less destructive subjects of the experiment are accompanied by the development of activation processes of specific and nonspecific character (α₁-rhythm power loss and β₂-rhythm power growth). This allows critical assessment of the incoming stimuli, generation of adequate behavioral responses, and inhibition of aggression. In the group of the subjects of the experiment with a high level of destructiveness activation, the criteria are less distinct. The criteria of excessive activation from diencephalic structures are observed (Δ rhythm power growth), which may be connected with the development of earlier and less stable mechanisms of behavior regulation and help to select more primitive behavioral models, including aggression.
