title: [Use of spectral correlation method in a study of human emotional states].
abstract: Application of a new approach to EEG analysis, i.e. of the method of spectral correlation, permitted identification of significant differences in spatial distribution of spectral power correlation for emotions of different quality, namely: anger and fear. It was shown that against the background of fear the topographic distribution of intracortical connections in the delta band was more extensive and included frontal, central, temporal, parietal and occipital regions. The emotion of anger evoked changes in the picture of spatial distribution of intracortical connections in the alpha band which resulted in appearance of a powerful focus of connections in the frontal regions. The greatest number of connections was found for the emotion of anger in the beta band--22 statistically significant correlations. Thus, a generalization of connections in the EEG high frequency bands is noted for the emotion of anger which is not characteristic of the emotion of fear.
