In experiments on observing and performing social gestures, the level of mu rhythm suppression is associated with the activity of the mirror neuron system (MNS), which is responsible for the perception and understanding of nonverbal signals in social communication. In turn, while MNS activity may be associated primarily with empathy, it is also associated with other psychological and demographic factors affecting the effectiveness of cortical neural networks. In this study, we verified the influence of empathy, state and trait anxiety levels, presence and number of children, and age on the mu-suppression level in 40 women. We used 32-channel EEG recorded during observation, and synchronous execution of various hand movements. The ICA infomax method was used for decomposing and selecting the left hemisphere component of the mu-rhythm. Mu-suppression was higher in women with one child, with higher levels of empathy, and with lower anxiety levels. It is possible that MNS activity is stronger in women during parental care.
在观察和执行社交手势的实验中，mu 节律抑制的水平与镜像神经元系统（MNS）的活动有关，MNS 负责感知和理解社交交流中的非言语信号。反过来，虽然 MNS 的活动可能主要与同理心有关，但它也与影响皮质神经网络有效性的其他心理和人口统计学因素有关。在这项研究中，我们验证了同理心、状态和特质焦虑水平、子女的存在和数量以及年龄对 40 名女性 mu 抑制水平的影响。我们使用了在观察和同步执行各种手部运动期间记录的 32 通道 EEG。ICA infomax 方法用于分解和选择 mu 节律的左半球成分。在有一个孩子、同理心水平更高和焦虑水平更低的女性中，mu 抑制水平更高。在父母照顾期间，MNS 活动在女性中可能更强。
