Experiment device and experiment method for animal instinct fear behaviors

Abstract

The invention discloses an experiment device and experiment method for animal instinct fear behaviors, and relates to the technical field of biological engineering. The experiment device comprises a camera shooting system arranged at the upper portion and a first experiment box for containing a predator, multiple partition plates are arranged in a center experiment box, and space between the firstexperiment box and the center experiment box is divided by the multiple partition plates into multiple movable boxes; each second experiment box can contain prey animals and is communicated with thecorresponding movable box through a connecting channel; each movable box is connected with the corresponding second experiment box through one connecting channel, and openings are formed in the connecting portions between the connecting channels and the movable boxes and the second experiment boxes for communication. The experiment method for the animal instinct fear behaviors adopts the experiment device. By means of the experiment device, multiple pieces of prey animals can be simultaneously experimented, the same predator is used, and the experiment efficiency is high; the experiment methodis reasonable in step, the experiment efficiency is high, and an experiment result is more accurate.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to an experimental device and an experimental method for animal instinctive fear behavior. Background technique [0002] Fear behavior, as one of the six basic emotional behaviors, plays a vital role in the survival of animals. Fear includes conditioned fear and instinctive fear. Instinctive fear refers to that which does not need training and learning. Being able to avoid danger and gain more possibility of survival. By analyzing the brain neural circuits behind the formation of fear, the pathological research and clinical research of the above diseases are of great significance. In the laboratory, because rats are predators of mice in the natural environment, mice will have instinctive fear when they see rats, so experimental devices are often designed based on this, and rats and mice are used as test subjects , that is, the rat is the predator and the mouse is the prey....

AI Technical Summary

Problems solved by technology

[0006] (1) Each experimental device can only measure the instinctive fear behavior of one mouse. It is necessary to prepare multiple experimental devices to test multiple mice. The experiment time is long and the efficiency is low;

[0007] (2) In the same experimental device, replace multiple mice for multiple experiments, and share the same rat as a predator each time. After multiple experiments, the rats will be tired and unwilling to contact with mice, which will affect the experimental results accuracy; if the tired rats are replaced, it will not only cause a waste of rats, increase the cost of the experiment, but also increase the experimental variables, which will also affect the accuracy of the experimental results
