脑电同步陛分析在癫痫机制研究中的应用

EEG phase synchronization analyse in study ofepilepsy

脑电相位同步性是研究癫痫超同步放电机制的方向之一。介绍了应用Hilbert变换提取脑电的瞬时相位的方法，分析脑电相位同步性的互相关法、互信息法和同步指数法，以及脑电信号的小波变换，综述了以上方法在癫痫发作的超同步放电机制研究中的应用。

EEG phase synchronization is one of researches studying mechanism of epilepsy hypersynchronization discharge. This article introduces the extraction of instantaneous phase of EEG using Hilbert transform and development of the EEG phase synchronization methods including Cross-Correlation function, Mutual-Information, Synchronous-Index and EEG wavelet. The applications of the methods in analysis of the EEE hypersynchronization in epilepsy are reviewed.
