Abstract

Pattern-reversal visual evoked potentials (PRVEPs) were tested in 11 sets of monozygotic (MZ) twins and 22 sets of dizygotic (DZ) twins matched on age, sex and educational level. They ranged in age from 7 to 15 years. The PRVEPs of MZ twins exhibited a significantly greater degree of similarity than those of DZ twins. The peak latencies and amplitudes of PRVEP components obtained from MZ twin pairs were significantly correlated. The correlation coefficients for the peak latencies of the P2 (or P100) component were the only ones to differ significantly between the DZ twins of the same sex and DZ twins of opposite sexes. These coefficients, obtained using PRVEPs, were much greater than those obtained with flash visual evoked potentials.

摘要

对11组年龄、性别和教育水平相匹配的同卵双胞胎（MZ）和22组异卵双胞胎（DZ）进行了模式翻转视觉诱发电位（PRVEP）测试。他们的年龄在7至15岁之间。同卵双胞胎的PRVEP表现出比异卵双胞胎更高的相似程度。从同卵双胞胎对中获得的PRVEP成分的峰潜伏期和波幅显著相关。P2（或P100）成分峰潜伏期的相关系数是同性别的异卵双胞胎和异性别的异卵双胞胎之间唯一有显著差异的系数。使用PRVEP获得的这些系数远大于使用闪光视觉诱发电位获得的系数。
