Spatial distribution of coefficients of asymmetry of brain bioelectrical activity during the experiencing of negative emotions.

Significant differences in the spatial distribution of the coefficients of asymmetry of the power of bioelectrical activity were identified in negative emotions of different qualities (anger and grief). In the case of the sthenic (excitable) emotion anger, there was an increase over baseline in the positive value of the coefficient of asymmetry in the anterior areas and the beta2 range, while for the asthenic emotion grief, there was an increase in the negative value of the coefficient in the beta1 range and a generalized increase in slow-wave activity.
