Utilization of a new approach to EEG analysis, i.e., spectral correlation, allowed significant differences in the spatial distribution of correlational relationships in spectral power to be identified for emotions of different qualities, i.e., anger and fear. In conditions of fear, the topographic distribution of intracortical connections in the delta range was more extensive and included the frontal, central, temporal, parietal, and occipital areas. The emotion of anger induced changes in the pattern of the spatial distribution of intracortical connections in the alpha frequency range, such that a powerful frontal focus of connections formed in the frontal areas. The largest number of connections in the beta2 band (22 highly significant connections) was seen for the emotion of anger. Thus, generalization of connections in the high-frequency EEG ranges occurred in anger, while this was not characteristic of fear.
采用一种新的脑电图（EEG）分析方法，即频谱相关性分析，能够识别出不同性质情绪（即愤怒和恐惧）在频谱功率相关关系的空间分布上存在显著差异。在恐惧状态下，δ频段内皮质内连接的地形分布更为广泛，包括额叶、中央、颞叶、顶叶和枕叶区域。愤怒情绪会引起α频率范围内皮质内连接空间分布模式的变化，从而在额叶区域形成一个强大的额叶连接焦点。愤怒情绪在β2频段（22个高度显著连接）中出现的连接数量最多。因此，愤怒时高频EEG范围内的连接会出现泛化，而恐惧则没有这种特征。
