关于经典事件相关电位(cognitive evoked poten-tial)的关联性负变(contingent negative variation,CNV)和P300已有介绍。现再介绍事件相关电位领域的一项新指标——失匹配负波(mismatch negativity,MMN)。原理与方法事件相关电位概念是指受试者注意到某客体对其进行高级认知加
Contingent negative variation (CNV) and P300 have been introduced for the classical evoked potential. We will now introduce a new indicator of incident-related potentials-mismatch negativity (MMN). Principle and method of event-related potential concept refers to the subject noticed that an object to its advanced cognitive plus
