利用计算机图像处理技术进行动物行为的药理学研究，已成为国标药理学界的发展趋势。为 此．作者在国内首先采用计算机自动控制与图像处理技术，对用于促智药物研究、主要测试动物空间学 习能力的水迷宫进行了改进．通过自行编译的软件程序．将动物在水迷宫中游泳的全过程经摄像后被计 算机识别，变为动物的实时活动轨迹图像在屏幕上进行动态显示．同时提供学刁分数、到达平台时间、进 入盲端错误次数、游泳距离及速度等指标，这样使得有效信量尽可能的多．保证所获的实脸结果更为 科学容观、准确可靠。

Using computer-aided control and video-tracking techniques to screen and study new drugs in animals has been forging rapidly. We applied those techniques to develop a computer-aided system for measuring water-maze performance. mainly spatial learning in the rat and mouse. The program utilized the video-tracking capabilities to measure the subject's attempt to search out the goal platform in square water-maze.The software in the system was designed in modularity and programmed with C++ language. The interfaces were designed as user friendly.The functions included,but not limited to:allowing the users to collect data including number of entries into culs de sac (which is scored in terms of number of errors);the latency period to reaching the goal;the learning in-dex (LI = total number of correct responses/total number of correct responses+total number of error responses.) and the swimming speed;providing hardcopy of screen graphics and results by various printers ;data file saving in and loading from hard disk and floppy disks,a unique approach to scientific data analysis.The computer-aided system made information refined as much as possible and guaranteed experimental results more scientific and reasonable.
