As a common laboratory animal, large mice are an ideal model for exploring some basic mechanisms of emotional and motivational functions. These studies mainly use dominant behavioral measures, such as animals will get close to satisfying and vice versa. Previous motivational and emotional state measurements were inferred by physiological indicators such as heart rate, adrenal ketone secretion, or brain animals. On this basis, two aspects of behavioral research can be carried out by acquiring the ultrasound (USV) of animals. One is the emotional state of animals, and the other is animal social behaviors such as mating, child-raising, play, attack and defense. Etc.), can be widely used in biomedicine, neuroscience, experimental psychology, metabolic related research.
On August 30th, 2016, the engineer of Beijing Yiketai Ecological Technology Co., Ltd. successfully installed and debugged the rodent ultrasound (USV) monitoring system at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, which can be used for schizophrenia in genetically manipulated mouse models. , the pathogenesis of autism and neurodegenerative diseases.

It should be emphasized that the sound spectrum analysis technology can be used in conjunction with animal respiratory metabolism techniques (including SSI animal respiratory metabolism technology, Promethion animal behavior and metabolic monitoring technology) and environmental monitoring factors to more comprehensively monitor animal feeding patterns, behavioral patterns, Animal sleep activity, exercise and metabolism, temperature heart rate, animal learning and memory behavior, animal emotion and motivation behavior, metabolism and influencing factors, etc., can also be used in conjunction with other animal behavioral, physiological, and biomedical instruments.
Case 1 Scientists at the Max Planck Institute in Germany used the "SSI Animal Respiratory Metabolism Technology and USV Animal Ultrasound Generation" technique to publish "Metabolic costs of bat echolocation in a non-foraging context support a role in 2013" in the International Journal of Physiology. The article "Communication" introduces the energy consumption strategy of bat echoes and the scientific hypothesis that USV ultrasound occurs in bat social communication.

Case 2 Scientists at the University of Melbourne's Institute of Neuroscience and Mental Health published "Elevated paternal glucocorticoid exposure alters the small noncoding RNA profile in sperm and modifies anxiety and depressive phenotypes in 2016" in the Transl Psychiatry Journal of Psychiatry. The article "The offspring" mainly introduces the molecular mechanism of glucocorticoids during the transmission of stress-induced characteristics of maternal-progeny.
