Introduction: The internal mental activity process of humans and animals cannot be directly observed. Scientists can only speculate on the processes that occur in the brain based on the observable stimulus response. Research on the memory process in the brain can only be learned or implemented by humans or animals. After a certain task, at a certain interval, measure their operational performance or reaction time to measure the coding form, storage capacity, retention time, and the conditions on which they depend, etc. of these processes. The basis of the learning and memory experiment method is conditioned reflex, and various methods are derived from this. The shuttle and dark experiment is one of the more commonly used methods. The advantage of this method is that it is simple and easy to implement. It can not only observe the influence of drugs on the memory process, but also observe the influence on academic performance. It has high sensitivity and is especially suitable for preliminary screening of drugs. The YLS-17B dark avoidance shuttle tester is an economical and practical instrument that can be used for dark avoidance experiments, shuttle experiments or anxiety experiments. The instrument can be equipped with two kinds of experimental boxes, large and mouse, for large and mouse avoiding dark experiments, shuttle experiments, and anxiety experiments. The instrument has the characteristics of LCD display, convenient setting, accurate counting, intuitive image, compact structure, convenient maintenance, and safe use. It is suitable for scientific research and teaching. It is a variety of intelligence and brain, memory, anti-aging drugs and health products. Screening, development and development of indispensable tools.
