目的：最近的脑成像研究表明，人类的镜子系统除了在观看他人动作时变得活跃外，还对与特定动作相关的抽象视觉和听觉刺激做出反应。方法：使用脑电技术，我们测量了音乐家和非音乐家听音乐时感觉运动速度的事件相关去同步化(MU-ERD)，观察正在演奏的乐器的电影，并观察相应的乐谱的静态图像。结果：音乐家在观察乐谱和音乐表演时，表现出明显的MU-ERD。结论：我们的结果表明，人类的运动系统通过在任意的、非音乐家和音乐之间形成功能联系来帮助感知和理解过程意义：这项研究在现有文献中独一无二地增加了抽象图像，证明当抽象图像被形成适当视觉-运动关联的专家观看时，能够触发“动作理解”系统。(C)2010年国际临床神经生理学联合会。爱思唯尔爱尔兰有限公司出版。版权所有。
Objective: Recent brain imaging studies have demonstrated that the human mirror system, in addition to becoming active while viewing the actions of others, also responds to abstract visual and auditory stimuli associated with specific actions. Here, we test the hypothesis that when musicians read sheet music an associated motor act is automatically recruited in the same way as when we observe the actions of others.Methods: Using EEG, we measured event related desynchronization of the sensorimotor mu rhythm (mu-ERD) while musicians and non-musicians listened to music, observed movies of a musical instrument being played and observed a static image of the corresponding sheet music.Results: Musicians showed significantly greater mu-ERD than non-musicians when observing sheet music and musical performances.Conclusions: Our results demonstrate that the human motor system aids in the process of perception and understanding by forming functional links between arbitrary, abstract percepts and associated acts.Significance: This research uniquely adds to the existing body of literature by demonstrating that abstract images are capable of triggering an "action understanding" system when viewed by experts who have formed the appropriate visual-motor association.
