The investigation of sleep in twins represents one of the major methods for measuring the genetic contributions to sleep in humans. This paper reviews two twin studies in which the sleep EEG was recorded during three consecutive nights in young monozygotic (MZ) and dizygotic (DZ) male twins. The analyses, based on average values of repeated sleep recordings, indicate that a significant proportion of variance in stages 2, 4, and delta sleep appears to be genetically determined. Genetic influences on rapid-eye-movement sleep were found inconclusive, but this conclusion is limited by the relatively small size of the sample studied.
对双胞胎睡眠的研究是衡量基因对人类睡眠影响的主要方法之一。本文回顾了两项双胞胎研究，在这两项研究中，对年轻的同卵（MZ）和异卵（DZ）男性双胞胎连续三晚进行了睡眠脑电图记录。基于重复睡眠记录的平均值进行的分析表明，2期、4期和δ睡眠中相当一部分的变异似乎是由基因决定的。关于快速眼动睡眠的基因影响尚无定论，但这一结论受限于所研究样本规模相对较小。
