简单介绍:
动物穿梭箱实验(Shuttlebox)是定量测定动物行为学改变的重要手段,动物穿梭箱属于经典的联合型学习条件反射,动物通过学习能回避有害的刺激。底部为不锈钢栅,使用电流加非条件刺激,电击动物足底。顶部配置有噪声发生器或光源,用来产生条件刺激。条件刺激数秒钟后电击。若在**刺激安全间隔期内大鼠逃向安全区则为主动回避反应;如果在条件刺激安全间隔期内大鼠未逃向安全区,则通以交流电击后逃向安全区的为被动回避反应阳性,否则为主动、被动回避反应阴性,此为一个循环周期。经过反复训练后,只给条件刺激,大鼠即逃到对侧安全区以逃避电击,此即形成了条件反射或称主动回避反应,计算机自动控制系统可记录相关的动物行动参数。主动回避时间是指动物接受条件刺激的时间长短,该值越短,说明动物主动回避反应越迅速,学习记忆能力越强。
详情介绍:
       动物穿梭箱实验广泛用于学习记忆功能、认知神经科学、神经生理学、神经药理学、认知功能退行性变性等实验研究方面的研究,简单易操作,容易判别结果,可信度高,既可单独作为检测实验提供课题参数,也可以作为其他学习记忆和认知功能实验的辅助或预筛选实验。
       动物穿梭箱由两部分组成:一部分是穿梭箱,是检测动物行为的场所,该设备中装有传感系统,可以接受动物的活动行为信号并传送到计算机。第二部分为软件系统,主要包括实验程序的设置,程序的执行,信号的采集(PCI接口),实时显示和数据结果,BMP结果,EXCEL结果输出打印等。
 
    1.完全电脑化双向逃避条件系统。
    2. 软件控制光线,休克应用。
    3.软件控制刺激声• WAV文件用于听觉鉴别。
    4.可选简易程序编辑器,用于产生用户自定义试验程序。
    5. 采用视频摄像跟踪技术,实现了实验过程的自动化,避免了人工计数引入的主观误差和对实验动物的干扰,增加了实验结果的真实性和可靠性。
    6.可插入 避暗测试仪箱体,需要加一个可选的被动逃避变换元件
