Detailed Product Description: | 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 darkroom, half bright room, connected to the middle of a small hole. Bottom darkroom copper grid covered with energized. Animals into the darkroom that is subjected to electric shocks. The experiment is simple, the more the reaction tank, while the more trained animals. In the incubation period, the number of errors as an indicator, the difference is relatively small animal. Memory processes, especially for memory retrieval have a higher sensitivity. 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 task parameters, it can be used as learning and memory and other cognitive functions experiment auxiliary or pre-screening test. This system is a way of tracking via camera video analysis system. The system imaging systems, computer stimulator 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 to Excel, and histogram Figure \ Curve \ 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 passive avoidance test, but were anxious to learn the system very easy to do helplessness model using video camera tracking technology, the automation of the experimental process, avoiding the subjective errors introduced by manual counting and experiments animal interference leading core algorithm, effectively guarantee the accuracy of the identification of noise immunity and user-settable independently of one another experimental data archive folder, easy to test data management can be time record video images in a variety of display indicators provide track map, locus 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. For research and computer-aided instruction (CAI), the original video images can be recorded, and provide complete experimental database functions, as a true record of research and future teaching demonstration material. Hardware Features Hardware Specifications Hardware parameter analysis system uses an embedded microcontroller as the main control center, experimental constant current to stimulate activity box external dimensions: 700 × 260 × 430mm light box Activity voice delay, voltage and current values ??using the software directly set . White box and black box inside, respectively size: 250 × 185 × 300mm on camera obscura activity time for each electrode has an adjustable peak square wave signal input voltage AC220V shuttle frequency cyclic shift of the electrodes are used pulsating stimulation, the animals withstand the current a constant value, compared with the traditional fixed electrode stimulation, avoiding the animal to stand on the same electrodes can stimulate the shortcomings electrical grid limit adjustment range: 0.04 ~ 3.5mA, adjust the step size 0.02mA, current error is less than 0.04mA can be arbitrarily set as desired. Stimulating sound delay 0-255 seconds. Activity light box camera obscura activities away from the present system all signals are transmitted using the USB interface power grid voltage adjustment range: 30 ~ 120V (peak square wave), adjust the step size 1V, the peak voltage error is less than 5% of the incubation period of the stimulation system suitable for different the size of the animal square wave electric gate on each stimulus frequency 96Hz, the error of 1% error count imaging system parameters: Camera brand SONY Box Camera color black and white or color resolution 540 lines / 600 lines Minimum illumination <0.005Lux video capture card USB2 0.01 External power supply 12V 2mA |
