摘要
事件相关电位(ERP)是人对客体进行认知加工(注意、记忆、思维等)时,在头颅表面所记录到的大脑电位变化。ERP由多种与认知功能相关的成分构成,包括早期成分,失匹配负波(MMN),N2家族,P3家族,语言加工相关的ERP成分等。通过对ERP这些成分的分析,可以深入探究人类大脑的认知功能,并且具有重要的法医学应用价值。

ERP consists of a variety of cognitive function and related components. Including early composition, mismatch negativity （MMN）, N2 family, P3 family, and other related components of language processing. These components are closely related to human cognitive function,the research of ERP can lead to a deeper understanding of cognitive function of human brains and has important application value of forensic medicine.
