在这里，我们研究了白天小睡对一天内虚拟迷宫表现变化的影响。参与者在虚拟迷宫任务训练后要么小睡一会儿，要么保持清醒。训练后睡眠在以后的重新测试中提供了明显的表现优势，但仅限于那些先前有在三维 (3D) 环境中导航经验的参与者。有经验的玩家的表现改善与富含 Delta 的第二阶段睡眠相关。目前的数据补充了啮齿类动物在导航后 NREM 睡眠期间重复学习相关大脑活动的观察结果，表明 NREM 睡眠赋予人类空间记忆性能优势。
Here, we examined the effect of a daytime nap on changes in virtual maze performance across a single day. Participants either took a short nap or remained awake following training on a virtual maze task. Post-training sleep provided a clear performance benefit at later retest, but only for those participants with prior experience navigating in a three-dimensional (3D) environment. Performance improvements in experienced players were correlated with delta-rich stage 2 sleep. Complementing observations that learning-related brain activity is reiterated during post-navigation NREM sleep in rodents, the present data demonstrate that NREM sleep confers a performance advantage for spatial memory in humans.
