ZH-500x-type passive avoidance test video analysis system for use with a mouse or rat habits tend to avoid bright dark design means half the darkroom, half of the next room, there is a hole in the middle is connected. Bottom darkroom copper grid covered with energized. Animals into the darkroom that is subjected to electric shocks. This experiment is simple, the more the reaction tank, but more trained animals. In the incubation period, the number of errors as an indicator, the difference is relatively small animals. On memory processes, especially memory reproduction have a higher sensitivity. The experiment is widely used in learning and memory function, experimental research study of neuroscience, neurophysiology, neuropharmacology, cognitive degenerative cognitive function, easy to operate, easy to discrimination result, high reliability, either alone topics as the detection experiments provide parameters can also be used as learning and memory and other cognitive functions secondary or pre-screening test experiments. This system is a video tracking mode by the image analysis system. The system camera systems, computers, stimulators three major components as the hardware basis, the experiment does not need to make a special mark in experimental animals. Software identification algorithm uses a trajectory prediction, local and global combination of search technology, which could be tracked and recorded in experimental animals (mice and rats) position, with an open, system scalability, the results can be imported into Excel, and histograms Figure \ curve \ trajectory processing, user-friendly in SPSS, SAS and other biological analyzes software for further analysis and processing. Second, the software features of versatility, in addition to passive avoidance test, the conduct of anxiety, helplessness model of learning the system very easy to do using a video camera tracking technology, the automation of the experimental process, avoiding the subjective errors introduced by manual counting and experiments interference leading core algorithm animals, effectively guarantee the accuracy of the identification of immunity and the user can set independently of each other experimental data archive folder for easy management of experimental data can be timed to record video images in a variety of ways to display indicators provide track Figure trajectory coordinate points and targets results export capabilities. Video file format support AVI compression format, the compression ratio is high, can effectively reduce the storage space, and is conducive to long experimental observation. Oriented research and computer-aided instruction (CAI), capable of recording the original video images, and provide a complete experimental database functions as a true record of research and future teaching demonstration material. ZH-600 type large mouse passive avoidance instrument is ZH-500-type passive avoidance upgrade board, is one of the instruments of learning and memory and drug research indispensable. Passive evade detection reaction and mice, learning and memory research. The main technical indicators: the incubation period. After several years of experiments, carried out a number of improvements, and now most of the domestic research and educational institutions have been using this instrument for scientific experimentation. Features: 1, no more than human observation and manual timing; 2, the LCD monitor can automatically record the experimental data and results, dynamic real-time display of the experimental parameters; 3, high reliability infrared detectors for rapid detection and accurate measurement of mice latency and errors; 4, the flexibility to choose through the key and set up an experiment to stimulate the current time, year, month, date can be set; 5, flexibly configure the printer, you can print the experimental data field; 6, activity boxes of single-row Transparent optimized design, easy and intuitive comparative observations, elegant appearance; 7, the inner sliding drawer boxes, easy to clean mouse droppings, health; 8, timing accuracy, high precision; 9, beautiful and convenient touch membrane keypad, long service life.
