Abstract:
Statistically significant differences were revealed in the spatial distribution of the asymmetry coefficients in the brain bioelectrical activity for different negative emotions. In case of the asthenic emotion (anger) the asymmetry coefficients in the beta-2 band were positive and greater in the frontal part of the brain as compared to the background. When the subjects experienced (imagined) the asthenic emotion (grief), the asymmetry coefficients were negative in the beta-1 band and a generalized growth of slow-wave activity was observed.
