摘　　要：记录Ａ组３７例正常人随机点立体图刺激的立体视诱发电位（Ｓ－ＶＥＰ）和Ｂ组４０例正常人图形翻转刺激的图形翻转视诱发电位（Ｐｒ－ＶＥＰ）。发现：Ａ组有１３．５％、３５．２％和５１．３％的受检者，其Ｓ－ＶＥＰ最大振幅分别出现在颅表Ｏ１、Ｏｚ及Ｏ２处。Ｂ组受检者Ｐｒ－ＶＥＰ最大振幅在Ｏ１、Ｏｚ及Ｏ２处的分布比例为２．５％、９２．５％和５％。两组资料有非常显著性差异。认为Ｓ－ＶＥＰ与Ｐｒ－ＶＥＰ的神经起源有差别，Ｓ－ＶＥＰ主要起源于１８区并有右侧大脑半球优势。he authors recorded the stereoscopic VEP(S-VEP)stimulated by random dot stereogram on 37 normalsubjects in group A and pattern reverse VEP (Pr-VEP)elicited by chechboard on 40 normal subjects in groupB. It was found that there were 13.5%,35.2%,51.3%subjects whose biggest amplitude of S-VEP occurredat O1,O_z,O2, respectively in group A and that was 2.5%,92.5%,5%at O1,Oz,O2 in group B,respec-tively. The difference of two group data is significant.The authors consider that there are differences in neu-ral origin between S-VEP and Pr-VEP and the S-VEP is predominant in right hemisphere of the brain.
