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.

摘要

不同负面情绪下大脑生物电活动不对称系数的空间分布存在统计学显著差异。在衰弱性情绪（愤怒）情况下，β-2频段的不对称系数为正，且大脑额叶部分相较于背景更高。当受试者体验（想象）衰弱性情绪（悲伤）时，β-1频段的不对称系数为负，且观察到慢波活动普遍增强。
