摘要： 本实验应用小站台水环境技术剥夺大鼠快速眼动相(REM)睡眠,比较了在学习后不同时间剥夺REM睡眠对记忆巩固的影响异同,结果证明:大鼠在学习后,立即剥夺REM睡眠24小时对记忆巩固明显不利;如在立即剥夺REM睡眠24小时后再让其恢复自由睡眠24小时,记忆成绩无明显改善;学习后允许自由睡眠24小时对记忆巩固明显有利;如在自由睡眠24小时后再行REM睡眠剥夺24小时,记忆成绩仍保持良好。说明学习后一段时间自由睡眠对于记忆的巩固是重要的,剥夺REM睡眠对于记忆的巩固明显不利。

Abstract: The retentions of memory were tested in 4 groups of Albino Rats. REMdeprivation was carried out on small platform surrounded by water for 24hrs after discrimination learning in Group 1. The free sleep was returned for24 hrs after REM deprivation in Group 2. The interval between REMdeprivation and learning was 24 hrs free sleep in Group. 3. The free sleep was allowed for 24 hrs after learning in Group 4 which was the control one.Then the retentions of memory were tested in all animals. The experiment demonstrated that REM deprivation had produced aconsiderable impairment to the consolidation of memory in Group 1. Theconsolidation of memory in Group 2 was little better than Group 1. However,the retentions of memory were better in Groups 3 and 4 in both of whichanimals were allowed to sleep freely immediately after learning or imposedto deprive REM sleep afterwards. The results indicated that it is very important for the consolidation ofmemory to sleep freely after learning, but REM deprivation is harmful.
