事件相关电位（Event Related Potential,ERP）是与实际刺激或预期刺激有固定时间关系的脑电位变化形成的一系列脑电波。它是一种特殊的诱发电位,属于近场电位。ERP包括P_s、N_1、P_2、P_(300)、S_w等成分,其中N_2、P_(3(N))属于内源性成分,和认知过程密切相关。近年国内外已有不少P_(300)的临床应用研究,现综述如下。1 P_(300)的概述 ERP中P_(300)近几年来广为人们注意并应用于临床
Event Related Potential (ERP) is a series of brain waves formed by the change of brain potential with a fixed time relationship with the actual stimulus or the expected stimulus. It is a special evoked potential, belonging to the near-field potential. ERP includes P_s, N_1, P_2, P_ (300) and S_w, among which N_2 and P_ (3 (N)) belong to endogenous components and are closely related to cognitive process. In recent years, there are many domestic and foreign P_ (300) clinical research, are summarized below. 1 P_ (300) in the overview of P_ (300) ERP in recent years has drawn great attention and applied to clinical
