摘要
长潜伏期听觉诱发电位不仅能反映大脑对声音信号的被动感觉处理过程,也能反应大脑在不同任务模式下的主动认识处理过程,因此被应用于认知功能的评估.本文就长潜伏期听觉诱发电位中的外源性成分(P1、N1、P2)和内源性成分(MMN/N2a、N2b、P3a、P3b)在轻度认知障碍和阿尔茨海默病中的研究现状进行综述,为国内开展相关研究提供一定的借鉴.
Abstract
The long-latency auditory evoked potential can not only reflect the passive sensory processing of sound signals in the brain,but also reflect the active cognitive processing of the brain in different task modes,so it is applied to the assessment of cognitive function.This article reviews the research status of exogenous components(P1,N1,P2)and endogenous components(MMN/N2a,N2b,P3a,P3b)in the long-latency auditory evoked po-tential in mild cognitive impairment and Alzheimer's disease,and provides some reference for those who carry out relevant research in China.
