摘　　要：脑电的同步被认为是脑功能区域整合或绑定的表现。本文从脑电同步的神经活动基础及空间尺度出发,阐述了同步的基本思想及定义,进一步从信号分析方法着手,系统地介绍了脑电相位同步的研究方法,并简要总结了不同方法之间的特点和差异。最后,讨论了相位同步检测中须注意的问题。Synchronous brain activities are considered as an indicator of the functional binding or integration. In this paper, based on the neural electric activities at various spatial scales, we explained the basic concept and measuring index of neural synchronization; then we summarized the main signal processing methods developed for phase synchronization analysis of electroencephalograph （EEG）, including the conventional signal processing method, and modern signal modeling approaches. Finally, the main differences among the different methods were compared and some critical problems in the study of EEG synchronization were discussed.
