YLS-3TB type platform logger An overview of internal psychological processes in humans and animals can not be directly observed, scientists can only be based on observable brain stimulation to speculate process occurs, the study of the brain and memory processes only After learning from a human or animal to perform a task or a certain time interval, measure their operating performance or response time to measure the encoded form of these processes, storage capacity, retention time, and they depend on the conditions, and so on. Learning and memory test method is based on the conditioned reflex, a variety of methods are derived therefrom come out, jumping method is one of a more common method, the advantage of this method is simple, one can simultaneously test more animals, you can observe the effects of drugs on memory processes can also be observed on learning, there is a high sensitivity, especially suitable for screening drugs. YLS-3TB model is based on the platform logger YLS-3T type jumping on improved recorder with LCD display, easy to set, count accurate, visually, compact structure, easy maintenance, use of safety features for research and teaching using various Zengzhi brain, improve memory, anti-aging medicine and health products screening, developed an indispensable tool. The instrument used microcomputer control animal behavior to step down judgment, you can set the test time and stimulation current, liquid crystal display and printing errors times and each step down the wrong time and with short-circuit alarm off function, also features computer interface, and computer After connecting the data can be read data and graphics processing on the PC, the instrument uses a split structure, convenient for cleaning and maintenance. Second, technical indicators automatically records the longest time: 18 hours minimum automatic recording time: 5 minutes (5 minutes or less manually stop) up to record the experimental data: 16 per group recorded the largest number of rooms: 250 detail records: 49 (refer to every detail second step down time) Timing Accuracy: 0.01 seconds clock setting item: year, month, day, hour, minute and second electric gate voltage adjustment range: 30V ~ 120V (peak square wave), adjust the step size 1V; electric gate limit Flow adjustment range: 0.06mA ~ 4.00mA, adjust the step size 0.02 mA five channels are free to set the input voltage: AC, 200V-230V 50Hz Power consumption: 30W Working temperature: 0-40 ℃ short circuit alarm sound data printing capabilities with computer interface can be connected box jumping mice (five rooms, each room 120 × 120 × 180mm), or rat jumping box (two-compartment, 300 × 300 × per room 280mm).
