文档介绍：睡眠不足对小白鼠学忆能力的影响
【摘要】目的本实验通过训练小鼠在水中如何找正确出口,测定睡眠不足对小鼠学忆能力的影响。方法首先我组实验人员用小鼠建立睡眠不足模型,然后对小鼠进行训练,再测定其找到正确出口的正确率。过30分钟后,再次测定其找到正确出口的正确率。实验以正常的小鼠及注射了东莨菪碱的小鼠作对照。结果睡眠不足组的学忆正确率比东莨菪碱组高。结论睡眠不足能降低小鼠的学忆睡眠不足东莨菪碱正确率

【Abstract】 Objective The effect of insufficient sleep for mice towards learning and memory. Methods First, we establish the model of insufficient sleep. Then we calculate the correct rate of finding exit after mouse's being trained, which acts as the index of learning. Then, after 30 minutes, we recalculate the correct rate of finding the exit as the index of memory .By contrast, we do the same way in the normal group and the scoplamine-injected group. Results The correct rate of learning and memory of insufficient-sleep group is lower than that of the normal group, but the correct rate of memory of insufficient-sleep group is higher than that of the scopolamine-injected group. Conclusion Insufficient sleep is negative to the learning and memory of mice.

生活在现在竞争越来越激烈的社会,睡眠不足对于大部分人来说是一个极普遍的现象,尤其是作为医学生的我们。然而在睡眠不足的情况下,我们的学忆能力是否会受到影响,这是广大同学十分关心的问题。通过这个实验,我们可以了解到睡眠不足对学忆能力的影响。如果是积极的影响,我们应当提倡;如果是消极的影响,我们应当尽量
