Describe the characteristics of a good model animal

The research objects of animal behavior include animal communication behavior, emotional expression, social behavior, learning behavior, reproductive behavior, etc. Due to the study of animal learning and cognition, as well as its relevance to neuroscience, animal behavior has had a certain impact on psychology, education and other disciplines. Giander is a leading supplier and service provider of microcirculation and microvascular research system, animal fine phenotypic behavior analysis system, and burn diagnosis system.

It has core competitiveness in optical imaging, computer vision and algorithms, anesthesia breathing, and multidisciplinary integration.

The question must have value, and the question should have some theoretical or practical value.

The problems must be scientific and realistic, and the realisticity of the topic selection should be mainly manifested in the fact that the selected problems should be scientific, the guiding ideology and purpose should be clear, and the basis for the argument should be substantial and reasonable. The scientificity of the topic selection is first manifested in the fact that there must be a certain factual basis, which is the practical basis of the topic selection; The scientific nature of the topic selection is also manifested in the fact that it is based on the basic principles of educational science, which is the theoretical basis of the topic selection.

The issues must be specific and clear, the selected issues must be concrete, the boundaries must be clear, the scope should be small, and they should not be too general.

The problems should be novel, and the selected problems should be problems that have not been solved or have not been completely solved by predecessors, and should be innovative and have a sense of the times through research.

The so-called feasibility means that the problem can be studied and there is a realistic possibility. In the specific analysis, it is necessary to consider the objective conditions such as data, time, funds, manpower, and theoretical preparation, as well as the researcher's own prior knowledge, ability, foundation, experience, and expertise, as well as the materials he or she has about the topic, and his interest in the topic.
