Animal chronic fear stress meter based on danger method

Abstract

The invention relates to an animal chronic fear stress meter based on a danger method, and aims at effectively solving the problem that an existing chronic fear psychological stress animal mold has relatively high body stimulation such as electric shock. According to the technical scheme, a speed reducer is fixedly arranged at the bottom of a bracket; a runner and a turntable are connected with each other through a rotating shaft and then are fixedly arranged at the top end of the bracket by a rotating shaft sleeve; the rotating shaft of the speed reducer is connected with the runner at the top end of the bracket by a motor belt; a box body is in a flat double-disk shape; one side of the box body is completely blocked, and is fixedly arranged on the turntable; a through hole is formed in the center of the other side of the box body; and a plurality of steps are arranged on the inner wall of a circular ring part between the disks on two sides of the box body at equal intervals. The animal chronic fear stress meter is simple and convenient to operate and high in practicability; animals can be in a danger continuously to generate fear psychological stress; meanwhile, relatively high body stimulation such as electric shock is avoided; and thus, the animal chronic fear stress meter is an innovation in the chronic fear psychological stress animal mold.

Description

technical field [0001] The invention relates to a stress experiment instrument, in particular to an animal chronic fear stress instrument based on the danger method. Background technique [0002] Fear is a common negative emotion. Transient fear will not cause obvious harm to people, but the harm of long-term fear to human physical and mental health cannot be ignored. Epidemiological surveys and experimental studies have shown that chronic fear stress not only affects one's own physical and mental health, but also has a persistent impact on the emotional state, neurodevelopment and cognitive function of offspring. However, the mechanism by which chronic fear stress affects health is still unclear, and further research is urgently needed. Because research on human subjects is inconvenient due to ethical restrictions, animal experiments have become a necessary alternative. [0003] According to the different responses of the body, stress is usually divided into three cate...
