ZH-CSC-type shuttle test video analysis system (Shuttle box system) is an important means of quantitative determination of changes in animal behavior, is the classic reflex associative learning, animals can be avoided by learning harmful stimuli. Stainless steel gate at the bottom, plus the use of current unconditioned stimulus, electric shock animal foot. Top configured with a noise generator for generating the conditioned stimulus. Conditioned stimulus after a few seconds of electric shock. If the ringtone stimulation in rats fleeing a safe area safe during the interval was active avoidance response; if the conditions are safe interval period, no stimulation in rats fleeing a safe area, then through the exchange of electric shock after fleeing to safe areas for passive avoidance The reaction was positive, otherwise active and passive avoidance response was negative, this is a cycle. After repeated training, only to conditioned stimulus, rats that fled to safe areas contralateral to escape electric shock, namely the formation of a conditioned reflex or called active avoidance response, computer control system can record the relevant animal action parameters. Time is the active avoidance animals received conditioned stimulus duration, the value, the shorter, indicating the animals more active avoidance rapid response, the stronger the learning and memory ability. The experiment is widely used in learning and memory function, experimental research study of neuroscience, neurophysiology, neuropharmacology, degenerative cognitive cognitive function, easy to operate, easy to distinguish a result, high reliability, either alone As a testing laboratory to provide the subject parameter, can be used as learning and memory and other cognitive functions experiment auxiliary or pre-screening test. This system is a way of tracking by camera video analysis system. The system uses the imaging system, computer, stimulator three major components as the hardware basis, the experiment does not require special labeling experiments on animals. Software recognition algorithm using 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 \ profile \ trajectory processing, user-friendly in SPSS, SAS and other biological analysis of statistical software for further analysis and processing. Second, the software features of multi-function, in addition to the shuttle experiments, but were anxious to learn the system very easy to do helplessness model uses a video camera tracking technology, the automation of the experimental process, avoiding the subjective errors introduced by manual counting and experimental animals interference, increasing the authenticity and reliability of the experimental results. Powerful software system function, parameter-rich standardized index of industrial design, hardware rugged leading core algorithm, 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 image, in a variety of ways to display indicators provide trajectories, track and coordinate points index results export capabilities. AVI video file format supports compression format, high compression ratio, can effectively reduce the storage space, and is conducive to long experimental observation. Oriented research and computer-assisted instruction (CAI), the original video images can be recorded, and provide a complete test database functions as a true record of research and future teaching demonstration material. Hardware features of the hardware parameters analysis indicators embedded microcontroller hardware systems as the main control center, experimental constant current stimulation shuttle box Dimensions: 700 × 260 × 430mm proper incubation period for the first time the sound delay, voltage and current values ??using the software directly setting. Single box internal dimensions: 250 × 185 × 300mm on the correct total time latency for each electrode has an adjustable square wave signal peak input voltage AC220V active electrodes are used to evade frequency cyclic shift of each pulsating stimulation, the animals were subjected to a current of constant value, compared with the traditional fixed electrode stimulation avoids the disadvantages of limiting the electrical grid adjustment range because the animals standing on the same electrode can not be stimulated: 0.04 ~ 3.5mA, adjust the step size 0.02mA, the current error is less than 0.04mA, can be arbitrarily set as desired. Stimulating sound delay 0-255 seconds. The first error signal latency of transmission of all the total latency of the system in the wrong time are using the USB interface power grid voltage adjustment range: 30 ~ 120V (peak square wave), adjust the step size 1V, peak voltage error is less than 5% of the number of passive evasion Square wave stimulation system suitable for different sizes of animals on each electrical grid stimulus frequency 96Hz, 1% error of the number of errors camera system parameters: camera brand SONY Gun Camera color black and white or color resolution 540 lines / 600 lines Minimum illumination <0.005Lux video capture card USB2.0 external power supply 12V 2mA
