摘要： ERP的神经机制问题一直存在争议。诱发模型认为, ERP产生于触发事件诱发的确定性响应电位, 该诱发电位与背景脑电振荡相互独立。相位重排模型认为, 触发事件并不会诱发出一个独立于脑电信号的诱发电位, ERP产生于背景脑电节律振荡的部分相位重排。已有研究提供了各种实验证据以支持诱发模型或/和相位重排模型, 同时也引发了相关学者的诸多质疑。实验记录方式、数据处理及分析方法等方面的提高有利于进一步澄清ERP的神经机制。

Abstract: The neural origin of ERPs is still an open question. The evoked model considers ERP as a deterministic evoked activity embedded in background EEG while the phase reset model considers ERP as a partial phase resetting of the ongoing oscillations of EEG. The present review 1) summarized the experimental evidences that supported the two models; 2) discussed controversial arguments raised by related studies; 3) suggested the future research direction in ERP origin, such as developing signal recording and data processing techniques. It is believed that the review helps to deepen our understanding of the mechanisms underlying the generation of ERPs.
