                三、实验开展
                1. morris水迷宫(Morris water maze, MWM)SuperMaze动物行为学视频分析系统
                Morris水ζ 迷宫实验是一种强迫实验动物(大鼠、小鼠)游泳,学习寻找隐藏在水中平台的一种实验,Morris水迷宫主要用于测试实验动物对空间位置感和方向感(空间定位)的学习记忆能力,被广泛应用于学习记忆、老年痴呆、海马/外∴海马研究、智力与衰老、新药开发/筛选/评价、药理学、毒理学、预防医学、神经生物学、动物心理学及行为生物学等多个学科的科学研究╳和计算机辅助教学等领域,在世界上已经得到广泛地认可,是医学院校开ξ展行为学研究尤其是学习与记忆研究的首选经典实验。
                 
                2. T迷宫实验(T-maze)
                   T迷宫由1条干和2条臂构成。迷宫使动物在获取食物奖励时没有任何参考,只能根据自我※判断选取食饵正确摆放一端。一般在测试前几天对其食量进行限制,测试前2天对动物进行训练。之后进行正式测试,每日▅连续测试15次,每次测试间隔1min,共3d。                                                                                                SuperMaze动物行为学视频分析系统
                  The T-maze is a choice task.  The subject is placed in the base of the "T".  Following a short delay, it is allowed to explore the maze and choose to enter either the right or left arms.  The choice is scored according to variety of criterion, including spontaneous alternation, cued reward, or to indicate a preference.  Based on the criterion used in an experiment, the T-maze can be used to test learning and memory, preferences for stimuli or reward, or spontaneous alternation behavior.
                 
                3. 八臂迷宫(Radial Arm Maze)
                  Subjects are placed in the center of an eight-arm radial maze.  Four randomly chosen arms are baited with food pellets in opaque containers.  The subject is given the opportunity to visit all the arms and collect all the available food pellets.SuperMaze动物行为学视频分析系统  After a rentention delay, the subject is returned to the maze.  In win-stay conditions, the same four arms are baited, and the number of correct choices the subject makes in collecting the pellets is recorded. In win-shift conditions, the four arms NOT baited in the earlier trial are now baited, and the number of correct arm choices is recorded.  Each day, a new set of four arms is chosen randomly.
                八臂迷宫用来检测药物或大脑受损状态下学习和记忆方面的表现,它由八个完全相同↘的臂组成①,这些臂从一个中央平台放射出来,所以又被称为放射迷宫每个臂尽头有食物提供装置,根据分析动物取食的策略即进入每臂的次数、时间、正确次数、错误次数、路线等参数可以反映出实验动物的空间记忆「能力。相对而言,八臂迷宫操作简便、可行,而且能区分短期的工作记忆和长期的参考记忆,现已被广泛←用于学习记忆功能评价。
                  
                4. 自主活动、旷场实验(Open Field
                  The subject is placed in the activity chamber for a specified time period.  Activity levels and movement in threeSuperMaze动物行为学视频分析系统 dimensions are recorded by the activity system and can be analyzed for evidence of hyperactiviy, hypoactivity, anxiety, explorative behaviors, and stereotyped rotation.     
                自发活动旷场旷场分析系统是观察研究实验动物神经精神变化、进入开︾阔环境后的各种行为,例如动物对新开阔环境的恐惧而主要在周ζ边区域活动,在中央区域活动较少,但动物的探究特性又促使其产生◆在中央区域活动的动机,也可观察由此而产生的焦虑∞心理。中枢兴奋药物可以明显增加自主的活动而减少探究行为,一定剂量的抗精神病药物可以减少探究行为而不影响自主▆活动。
                 
                5. 高架十字▅迷宫(Elevated Plus Maze
                   高架十字迷宫是利用动物对新』异环境的探究特性和对高悬敞开臂的恐惧形成矛盾冲突行为来考察动物的焦虑状态。高架十SuperMaze动物行为学视频分析系统字迷宫具有一对开臂和一对闭臂,高架十字迷宫距离地面较高,相当于人站在峭壁上,使实验对象产生恐惧和不安心理。高架十⌒字迷宫被广泛应用于新药开发、药理学、毒理学、预防医学、神经生物学、动物心理学等多个学科的科学-研究和计算机辅助教学等领域,是医学院校与科研机构开展焦虑抑郁研究的经典实验。Xmaze 动物行为轨迹分析平台
                The animal is placed in the center of the apparatus and observed for a set time.  Measurements compare the include total time spent in the open and closed arms (and central platform) as well as entries into the open and closed arms.
                 
                6. 黑白箱实验(light dark box
                  The subject is placed in the dark portion of the box for a set period of acclimation time.  At the end of this period, a door separating the two compartments is opened.  The amount of time that the subject takes to emerge fully from the enclosed area into the open area is measured.
                SuperMaze动物行为学视频分析系统
                 
                7. 社交行为实验(social interaction)SuperMaze动物行为学视频分析系统
                  The subject is habituated to the test chamber and allowed to freely explore for a set time.   A novel animal is placed in one of the two enclosures, and the percentage of time the mouse spends in the section with the novel animal is compared to the time spent in the section with the empty enclosure.   In a later session, the time spent with the same animal might be compared to time spent with a newer, more novel animal.
                 
                 SuperMaze动物行为学视频分析系统
                8. 条件性位置偏△爱(Conditioned Place Preference
                   条件性位置偏爱实验(CPP)实验是目前评价药物精神依赖性的经典实验模型。该实验将实验〓动物(大鼠、小鼠)置于条件性位置偏爱箱的白色观察区,并给予精神依赖药物然后观察实验动物在条件性位置偏爱箱的黑色区和白色区ζ 的活动情况,白色区、黑色区以【及其中的灰*之间有小门可供动物自由穿梭。动物每次处于给药区就会在药物奖赏性效应的作用下对黑色和白*域产生位∴置上的偏好,其程度与药物的精神依赖性相关。SuperMaze动物行为学视频分析系统
                    A drug is injected and the subject is introduced to distinctive environment A.  This procedure is repeated for several trials.   During these conditioning trials the animal develops an association between the subjective state produced by the drug (often drugs that produce mood elevation or euphoria in humans) and the contextual cues present while the drug is active.  To test the conditioning, the animal is placed in an apparatus with drug-related cues in one compartment and neutral cues in the other. nbsp; If conditioning occurred, the animal will move toward the compartment containing the drug-related cues.
                In a Conditioned Place Preference experiment, subjects are returned to an apparatus were they can freely move between a compartment in which they were conditioned with drug-related cues, and a compartment with neutral cues.  If the conditioning was successful for positive, reinforcing drug states, they should spend more time in theSuperMaze动物行为学视频分析系统 compartment with drug-related cues。
                In a Conditioned Place Aversion experiment, subjects are returned to an apparatus were they can freely move between a compartment in which they were conditioned with an aversive stimulus, such as a shock; and a compartment with neutral cues.  If the aversive conditioning was successful, they should spend more time in the compartment with neutral cues.
