Animal behaviourology is a science specially used for studying animal behaviors and has relevance to multiple disciplines. With the development of science and technology, animal behavioral medical experiments have become an indispensable important means for the research of higher brain functions, and have an important position in the research fields of neurophysiology, neuropharmacology and the like. In the traditional animal behavioural medical experiment task, the animal can be informed how the animal needs to do as a pathological model experiment. During the research process, the memory can be divided into reference memory and working memory. In the training and testing process of the animal, firstly, reference memory is required to be completed through an experimental device, and the reference memory reflects the learning of relevant information (such as spatial clue positions, experimental rules and the like) of the animal to each testing stage in a task. Thus, in the process of forming the reference memory, the reference information should be present during each experiment. During the training test, the working memory of an animal refers to the ability to retain information between different trials in each conditioned reflex experiment. The experimental animals after one trial were able to erase this specific working memory, but the reference memory was kept unchanged. Therefore, the working memory only works in one test, and the reference memory belongs to the long-term memory.
