The differentiation of basic emotions by means of EEG power spectra has been discussed extensively by Machleidt et al. (1989). The present contribution concentrates on the interhemispheric coupling of different EEG-signals as depending on the modulation of these emotions. In the first part the estimation and interpretation of squared coherence spectra is outlined. Results from this technique are presented in the following section. Intention, Aggression and Joy are mainly characterized by an increase of alpha-coherence, whereas a decrease is seen for Anxiety and Sorrow. These effects showed a widespread distribution.
马赫莱德特等人（1989年）对通过脑电图功率谱区分基本情绪进行了广泛讨论。本论文着重关注不同脑电信号的半球间耦合，这取决于这些情绪的调节。第一部分概述了平方相干谱的估计和解释。该技术的结果将在以下部分呈现。意图、攻击性和喜悦主要表现为阿尔法波相干性增加，而焦虑和悲伤则表现为相干性降低。这些效应分布广泛。
