The purpose of this work was to study the reactivity of EEG mu-rhythm during observation, auditory perception and imitation of circular hand movements with a computer mouse, and its correlation with empathic ability of an individual. During observation of hand movements, we discovered a significant desynchronization of the mu rhythm in the hemisphere contralateral to the observed hand (electrode C3; a decrease by 6.9%). During auditory perception of the sounds of computer mouse movements (with eyes closed), we observed a significant decrease in the amplitude of the mu rhythm under electrodes C(z) (6.7%) and C3 (4.4%). During movement imitation, we discovered a decrease in the amplitude of the mu rhythm under electrodes C(z) (12.6%), C3 (23.2%) and C4 (16.7%). The result of self-assessment of empathic ability by the Questionnaire of Emotional Empathy of Mehrabian and Epstein was positively correlated (r = 0.47) with the averaged values of desynchronization of the mu rthythm under three central electrodes during auditory perception; during observation and imitation, no significant correlations were found. We suggest that empatic ability is more likely to correlate with the activity of "logically related" mirror neurons, than with that of "strictly congruent" ones.
这项工作的目的是研究在观察、听觉感知以及用电脑鼠标模仿圆形手部动作过程中脑电图μ节律的反应性，及其与个体共情能力的相关性。在观察手部动作时，我们发现与被观察手部对侧的半球（电极C3）的μ节律出现显著去同步化（下降6.9%）。在闭眼听觉感知电脑鼠标移动声音时，我们观察到电极C(z)（6.7%）和C3（4.4%）下方的μ节律振幅显著下降。在动作模仿过程中，我们发现电极C(z)（12.6%）、C3（23.2%）和C4（16.7%）下方的μ节律振幅下降。根据梅拉比安和爱泼斯坦的情绪共情问卷进行的共情能力自我评估结果，与听觉感知期间三个中央电极下方μ节律去同步化的平均值呈正相关（r = 0.47）；在观察和模仿过程中，未发现显著相关性。我们认为，共情能力更有可能与“逻辑相关”的镜像神经元的活动相关，而非与“严格一致”的镜像神经元的活动相关。
