背景和目的：为了研究白天小睡对程序性和陈述性记忆巩固的影响，患者和方法：经过一个正常的夜间睡眠，34名年轻的健康受试者被随机分配到一个午睡或醒来的条件约45分钟后，下午早些时候leaming程序性和陈述性记忆任务。受试者被控制的警觉性和皮质醇secretion.Results：下午午睡的睡眠阶段2为主，但也包含一些慢波睡眠（SWS）和快速眼动（REM）睡眠。小睡可以显着改善程序性记忆，但不能改善陈述性记忆。无论是午睡还是清醒，女性在陈述性记忆任务中的进步都比男性大。有没有组之间的差异，就皮质醇分泌或alertness.Conclusions：短暂的午睡有利于巩固程序性记忆。在睡眠和记忆的研究中，性别的可能混杂效应应该始终被考虑在内。(C)2006 Elsevier B.V.保留所有权利。
Background and purpose: To investigate the impact of a short daytime nap on procedural and declarative memory consolidation.Patients and methods: Following a normal night's sleep, 34 young healthy subjects were randomly assigned to a nap or wake condition of about 45 min in the early afternoon after leaming procedural and declarative memory tasks. Subjects were controlled for alertness and cortisol secretion.Results: The afternoon naps were dominated by sleep stage 2 but contained some slow wave sleep (SWS) and rapid eye movement (REM) sleep as well. Naps significantly improved procedural, but not declarative, memory. Females showed more improvement than males in the declarative memory tasks irrespective of nap or wake. There was no difference between groups with respect to cortisol secretion or alertness.Conclusions: A short nap is favorable for consolidation of procedural memory. The possibly confounding effect of gender should always be considered in research on sleep and memory. (C) 2006 Elsevier B.V. All rights reserved.
