Abstract

The P300 component of the auditory event-related potential was recorded from 10 pairs of monozygotic (MZ) twins and 11 pairs of dizygotic (DZ) twins during an auditory discrimination task. The within-pair similarity of P300 latency was significantly greater in MZ than in DZ twins. The within-pair similarity of P300 amplitude was not significantly greater in MZ than in DZ twins. These results support previous findings suggesting that P300 latency is largely genetically determined.

摘要

在一项听觉辨别任务中，记录了10对同卵双胞胎和11对异卵双胞胎的听觉事件相关电位的P300成分。同卵双胞胎中P300潜伏期的组内相似性显著高于异卵双胞胎。同卵双胞胎中P300波幅的组内相似性并不显著高于异卵双胞胎。这些结果支持了先前的研究发现，即P300潜伏期在很大程度上由基因决定。
