中文摘要       第一部分 上丘在REM睡眠中眼动控制机制的研究
       REM睡眠对于人类和动物的生理意义目前不十分清楚,在REM睡眠一些独有的现象如快速眼动,随意运动抑制,大脑电活动活跃等都是对睡眠的内在机制及意义进行研究的重要窗口,并且睡眠对于人类的生理和心理健康都是必须的,所以对REM睡眠的研究具有非常重要的科学意义和促进公众健康进步的重要价值。但是直到目前,该快速眼动运动的生成和控制机制到目前为止仍然不甚清楚,同时,基于REM睡眠中的快速眼动和清醒时的快速眼动很相似,所以做出如下假设:上丘参与了REM睡眠中快速眼动的控制。为了探讨上丘是否参与REM睡眠中的快速眼动运动的发生和调控,我们成功建立了两项独特的关键技术:上丘的精确完全损毁方法和长时程自由活动猕猴睡眠记录技术,应用这两项技术,我们采用损毁的方法观察上丘在REM睡眠中的快速眼动运动中的作用,并取得了一些初步结果。
     第二部分:猕猴前脉冲抑制测量系统的建立
       前脉冲抑制(PPI)现象在人类和其他高等动物中都广泛存在,经由测量PPI效应的程度能够反映大脑感觉门控功能的情况,并且作为测试指标,为许多精神疾病如精神分裂等提供了重要的诊断依据和研究范式。为了更好的研究精神分裂症等疾病的动物模型,我们建立了一套适合于我们使用的猕猴PPI测量系统,并且进行了多项测试。测试结果表明:该系统能够反映猕猴PPI效应的程度,但是被试动物在接受测试之前的训练对测试结果至关重要。
英文摘要   
Part I: The role of superior colliculus during REM sleep fast eye movement
     Fast eye movement, voluntary movement inhibition and highly activated brain activity are unique phenomenas during REM sleep, these phenomenas provides us opportunity to research the sleep mechanism , REM sleep is a specical state in which fast eye movement occurs that are similar to fast eye movement during wake state,. For sleep are necessities for human and animal living, research on REM sleep will make great scientific meaning and improvement of public health. Till now, it is still not clear that why there must be a sleep state . Based on the similarity between REM sleep fast eye movement and normal fast eye movement, we assume that superior colliculus which are well known as an important control unit in normal fast eye movement also teke part in the prosess of REM sleep fast eye movement. In order to investigate this issue, we estabilshed two unique key technics to find out whether superior colliculus are involved in this movemen: complete lesion of superior coliculcus and long term sleep electrophysiology recording and got some early results.
      Part II: Establlishment of monkey PPI measurment system
Prepulse inhibition(PPI) effect are wildly known in human and other animals, evaluation of PPI effect reflects the function of brain sensory gating. As an important measurement and research protocol, PPI effect and its evaluation are valuable for diagnosis of many mental diseases such as schizophrenia. We established a suitable device in order to measure PPI effect in monkeys and made a series of test. The test result suggests that this PPI measure device are effective in assessing PPI in monkeys, meanwhile whether receive pre-training are critical for the test result.
