摘要：

人类大脑运动皮质的Beta (15~30 Hz)和Mu节律(8~14 Hz)有共同的活动特征, 研究指出二者可能是联合的脑电成分。然而越来越多研究表明运动区Beta节律可能独立于Mu节律, 且具有特殊的功能意义。线索诱发的Beta节律降低、运动前Beta节律降低和运动后Beta节律回复增强都是Beta与Mu节律不同的活动形式, 表明运动区Beta节律有其独特的心理意义。本文主要对运动区Beta节律不同于Mu节律的活动特征及已有的理论解释进行了梳理和分析, 并结合儿童研究的数据, 从发展的角度对运动后Beta节律的理论假说进行了评述, 最后在此基础上为进一步探索运动区Beta节律的功能意义提出了研究的展望。

Abstract:

Beta (15~30 Hz) and Mu (8~14 Hz) rhythm in the human motor cortex have similar activity patterns associated with human actions, and have been viewed as two sub-components of one EEG mechanism for movement representation, planning, understanding, and execution. However, growing evidence suggests that Beta rhythm generated by motor cortex may be independent of Mu rhythm from the same regions. Thus, Beta synchrony might play a different functional role in human action. This review focuses on studies of the functional role of Beta rhythm, and emphasizes evidence that Beta modulation is independent of Mu modulation in is association with human action processing. Current theoretical hypotheses on the function of Beta modulation are discussed based on research on developmental population to help distinguishing ongoing arguments. Finally, future investigations of this topic are proposed.
