本文介绍了近年来国内外运用计算机累加技术

从人体头皮上引出的累加脑诱发电位作为疼痛客观测量方法的研究及其动态

脑诱发电位中某些早反应(潜伏期30毫秒左右)和晚反应(潜伏期160～260毫秒)的波形成份和疼痛关系密切.人脑诱发反应研究的进展为实验性疼痛的估价提供了新的方向。但还存在一些问题.In this paper a objective method of pain measurement with the cerebral evoked potential from scalpby computer average technique and the development in this field is presented.The components of earlyresponse (latency adout 3 ms) and late response (latency about 160-260 ms) in the cerebral evokedpotential were closely related to pain perception.In this review

it has pointed out the way for theevaluation of exprimental pain but some questions are still exist.
