Sleep not only protects memories from outside interferences, but also helps strengthen them, according to research that will be presented at the American Academy of Neurology's 59th Annual Meeting in Boston, April 28 May 5, 2007.


The study looked at memory recall with and without interference (competing information). Forty-eight people between the ages of 18 and 30 took part in the study. All had normal, healthy sleep routines and were not taking any medications. Participants were divided evenly into four groups a wake group without interference, a wake group with interference, a sleep group without interference and a sleep group with interference. All groups were taught the same 20 pairs of words in the initial training session.


The wake groups were taught the word pairings at 9 a.m. and then tested on them at 9 p.m. after 12 hours awake. The sleep groups were taught the word pairs at 9 p.m. and tested on them at 9 a.m. after a night of sleep. Just prior to testing, the interference groups were given a second list of word pairs to remember. The first word in each pair was the same on both lists, but the second word was different, testing the brain's ability to handle competing information, known as interference. The interference groups were then tested on both lists.


The study found that people who slept after learning the information performed best, successfully recalling more words. Those in the sleep group without interference were able to recall 12 percent more word pairings from the first list than the wake group without interference. With interference, the recall rate was 44 percent higher for the sleep group.


"This is the first study to show that sleep protects memories from interference," said study author Jeffrey Ellenbogen, MD, with Harvard Medical School in Boston, MA, and Fellow of the American Academy of Neurology. "These results provide important insights into how the sleeping brain interacts with memories: it appears to strengthen them. Perhaps, then, sleep disorders might worsen memory problems seen in dementia."

睡觉不仅从外部的影响中保护人的记忆,同时也强化了人的记忆能力。这个结论是根据2007年4月28日到5月5日在波士顿召开的美国神经病学学院第59届年会上发表的研究所显示的。

这项研究关注了人的记忆在外部影响和去除外部影响下,人的记忆对于一些信息的回忆程度。40个18到30岁的成年人参加了这个实验。这些人都有与常人一样的健康的睡眠习惯,同时也不靠吃药帮助睡眠。参与这被分成了4个小组,一组是没有外部干扰的、但是是一直醒着的,一组是由外部干涉记忆的、一直醒着的,一组是没有外来干涉的、睡觉的组,一组是睡觉的但是有外来干扰的组。在测试前所有的区都给他们一样的指定的20组词进行记忆。


The wake groups were taught the word pairings at 9 a.m. and then tested on them at 9 p.m. after 12 hours awake. The sleep groups were taught the word pairs at 9 p.m. and tested on them at 9 a.m. after a night of sleep. Just prior to testing, the interference groups were given a second list of word pairs to remember. The first word in each pair was the same on both lists, but the second word was different, testing the brain's ability to handle competing information, known as interference. The interference groups were then tested on both lists.
醒着的组在上午9点教给他们这些词,持续12个小时的清醒状态后,而后在晚上9点对他们进行测试。睡觉的那些组在晚上9点教他们这些词,在12小时睡眠后,在次日早上9点对他们进行测试。由于是先进行测试的组,受外界干扰的两个组又要求记忆第二组词。第一组的每对词相互之间都是一样的,但是第二组中每对词相互之间是不一样的,这样就能测试大脑对于这些具有冲突性数据的记忆效果。到时候,受干扰的组对两组词都要进行测试。|

研究发现在学习后便睡觉的那些组表现十分出色,他们成功地回忆起了大多数的词。而那些没有外界干扰的、睡觉的组能够比那些醒着的但没有外界干扰的那些组的成员能够回忆起第一组单词列表中多12%的词。而在有外界干扰的情况下,睡觉的组回忆起的单词量比不睡觉的组多出44%。

"这是第一个显示了睡觉能够排除外界干扰,保护人的记忆的实验,"医学博士,实验设计者,波士顿哈佛医学院的文学硕士Jeffrey Ellenbogen,及美国神经医学研究会成员说。"这个结果提供了十分重要的对于睡眠中的大脑和记忆之间是如何相互影响的方面的材料:看上去睡眠强化了大脑和记忆。接下来可能的情况是,睡眠的问题可能加重记忆的问题,从而导致痴呆的发生."
