[0002] Rat as a model organism is widely used in brain higher function and neuroscience research. Currently, animal behavior assessment is widely used in multiple fields of neuroscience, especially in animal model assessment of cognitive dysfunction related diseases, physiological mechanism research and other aspects. Cognitive dysfunction is usually manifested as impaired learning and memory ability, therefore, most behavior experiments are used to evaluate learning and memory ability, including the evaluation of working memory and reference memory. Working memory refers to short-term memory and information processing, while reference memory refers to a long-term memory or habit, which has longer duration and stronger anti-interference ability than working memory. Among them, maze experiment is a classic project of animal behavior experiment, and is one of the most commonly used experiments when studying the learning and memory ability of rats or mice, including Y-maze, T-maze and eight-arm maze. However, the current maze training is manually operated by experimenters in the experimental process, data collection and processing, and the recorded data is greatly affected by the subjective factors of experimenters, which affects its accuracy.

[0003] When using rats for experiments, it is necessary to implant an identification marker in each rat. Currently, the common method is to nail an identification chip on the ear of rat. However, the existing devices have the defect of not being convenient to use. UTILITY MODEL CONTENT
