镜像神经元系统（MNS）的发现使研究人员推测，该系统是从猴子的具身视觉识别装置进化到人类社交技能的关键系统。虽然社会互动调节镜像神经元放电的程度尚未被研究，但人们普遍认为MNS专门用于处理动画刺激。本研究采用脑电图mu波抑制作为MNS活动的指标。数据是在被试观看四段视频时收集的：(1)视觉白噪音：基线；(2)非互动：三个人向自己抛球；(3)社会行动，旁观者：三个人向对方抛球；(4)社会行动，互动：与视频3类似，只是偶尔会把球从屏幕上抛向观众。mu波受社会互动程度的调节，非互动条件下抑制最小，其次是社会行动、旁观者条件和社会行动、互动条件下抑制最大。这些数据表明，人类的MNS不仅专门处理动物刺激，而且专门处理与社会相关的刺激。
The discovery of the mirror neuron system (MNS) has led researchers to speculate that this system evolved from an embodied visual recognition apparatus in monkey to a system critical for social skills in humans. It is accepted that the MNS is specialized for processing animate stimuli, although the degree to which social interaction modulates the firing of mirror neurons has not been investigated. In the current study, EEG mu wave suppression was used as an index of MNS activity. Data were collected while subjects viewed four videos: (1) Visual White Noise: baseline, (2) Non-interacting: three individuals tossed a ball up in the air to themselves, (3) Social Action, Spectator: three individuals tossed a ball to each other and (4) Social Action, Interactive: similar to video 3 except occasionally the ball would be thrown off the screen toward the viewer. The mu wave was modulated by the degree of social interaction, with the Non-interacting condition showing the least suppression, followed by the Social Action, Spectator condition and the Social Action, Interactive condition showing the most suppression. These data suggest that the human MNS is specialized not only for processing animate stimuli, but specifically stimuli with social relevance.
