近年来，睡眠对记忆巩固的影响受到广泛关注。在人类中，这些研究主要集中在程序性记忆上，这种记忆被认为与海马体无关。在这里，我们证明睡眠对海马依赖性陈述性记忆也有持久的影响。在两个实验中，我们检查了高中生记忆词汇的能力。我们发现，当学习后几个小时内进行睡眠时，陈述性记忆会得到增强，与一天中的时间无关，并且在保留间隔期间受到等量的干扰。睡眠不足会对记忆力产生不利影响，经过一晚的恢复性睡眠后这种影响尤为明显。因此，在清醒间隔期间积累的疲劳可以被排除为一个混杂因素。
In recent years, the effect of sleep on memory consolidation has received considerable attention. In humans, these studies concentrated mainly on procedural types of memory, which are considered to be hippocampus-independent. Here, we show that sleep also has a persisting effect on hippocampus-dependent declarative memory. In two experiments, we examined high school Students' ability to remember vocabulary. We show that declarative memory is enhanced when sleep follows within a few hours of learning, independent of time of day, and with equal amounts of interference during retention intervals. Sleep deprivation has a detrimental effect on memory, which was significant after a night of recovery sleep. Thus, fatigue accumulating during wake intervals could be ruled out as a confound.
