Behavioristics device for testing negative emotion

Abstract

The invention provides a behavioristics device for testing negative emotion. The behavioristics device comprises a platform, a support frame and an arm body, wherein the platform is used for placing a to-be-tested object; the support is connected with the bottom of the platform; the arm body is arranged around the edge of the platform and is connected with the platform; the height of the arm body is greater than the maximum height of the to-be-tested object; the support frame is of a Y-shaped structure and comprises a first support frame end, a pivoting base, a second support frame end and a third support frame end, wherein one end of the first support frame end is connected with the bottom of the platform; the other end of the first support frame end is connected with the pivoting base; the second support frame end and the third support frame end are pivotally connected with the pivoting base; and an included angle between the second support frame end and the third support frame end is adjusted by rotation of the second support frame end and the third support frame end.

Description

technical field [0001] The disclosure relates to the field of neuroscience research, in particular to a behavioral device for testing negative emotions. Background technique [0002] Negative emotions such as anxiety and fear are highly conserved in the evolution of organisms for hundreds of millions of years. Negative emotions can trigger defensive behaviors, enabling organisms to respond to danger, thereby avoiding or reducing injuries and ensuring the individual’s health. Survive. There are two kinds of factors that cause anxiety, namely environmental factors and individual factors. Environmental factors can be rapid and acute or long-term and chronic. At the same time, whether an individual is prone to anxiety is affected by his sensitivity to external pressure. When an individual is anxious, his physiological state and behavior will change, such as showing high arousal or avoidance. These responses are not unique to anxiety; similar responses occur with fear, except t...

[0003] The height of the existing behavioral devices cannot be changed, but the size of mice and rats is very different, and the height of the same device has different fear effects on rats and mice, which may lead to distortion of test results and cannot be used for The difference test of the negative emotions of animals at different heights from the ground, so the fixed height of the device cannot meet the experimental needs

On the other hand, the behavioral test only reflects the degree of anxiety, and the behavioral device cannot form an absolutely safe or absolutely dangerous stimulus. In fact, the state of negative emotions is different in environments with different levels of danger, such as When animals are placed in a high-hanging and open environment, the animal's fear of heights will be amplified. In fact, there is no internationally recognized behavioral paradigm for testing rodents' fear of heights.
