A device and test method for testing the memory function of primate experimental animals

Abstract

The invention discloses a device and a test method for testing the memory function of primate experimental animals, including an experimental operation cage, a hard food dispenser, and a ventilation system, and the experimental operation cage includes an outer box and an inner box; The lower part of the front end of the outer box body is distributed with a protruding body, and a fruit block distributor is distributed in the protruding body; a food slideway is also distributed on one side of the protruding body, and the food slideway is used for connecting with the hard food. The food dispenser is connected; the inner box is in the shape of a rectangle, the lower part is provided with a waste tank and a support pipe, and the upper part is just corresponding to the inner wall of the outer box. The invention can make the primate experimental animals have a higher degree of cooperation in the test process, is less prone to impatient phenomena, can successfully complete the test and has higher test result accuracy.

Description

technical field [0001] The invention belongs to the technical field of testing the memory ability of primate experimental animals, and in particular relates to a device and a testing method for testing the memory function of primate experimental animals. Background technique [0002] Accurately testing the cognitive and memory abilities of primate experimental animals has always been a major technical problem in ethology, because conducting ethological tests on primate experimental animals increases the cooperation degree of primate experimental animals compared with other tests. A major factor, and the inability of people to communicate with primate laboratory animals. Therefore, in conducting such related experiments, when other experimental factors are under good controllable conditions, it is difficult to control the experimental cooperation of primate experimental animals. The emotions, patience, preference, and psychological factors of primate experimental animals wil...

AI Technical Summary

Problems solved by technology

[0003] 1. Experimental animals tend to show impatience in the test for about 5 minutes, and the cooperation degree drops significantly in about 10 minutes, which affects the accurate evaluation of cognitive memory ability and even fails to complete the test;

[0004] 2. After the test, the four walls of the box generally need to be cleaned, but this device directly fixes the electronic circuit on the box, which cannot realize direct water washing and disinfection as a whole, especially when testing infected experimental animals. , it is easy to spread the disease through the device, affect the experiment, and endanger the life safety of experimental animals

[0005] 3. The exhaust system of the device is not properly set up, and the direction of ventilation is from bottom to top, and because the animals excrement in the test is more, and the excrement bracket is located in the lower part, after the test is carried out for a period of time, the airtight device is full of odor, which directly affects the continuous cooperation of experimental animals, which in turn leads to inaccurate tests;

[0006] 4. Generally, it is aimed at fruits and hard granular food. Experimental animals prefer hard granular food, but hard granular food is prone to greasy feeling, so that experimental animals begin to appreciate hard granular food after eating hard granular food for about 8 minutes. Food anorexia, hard granular food no longer exerts its proper attractive force, which is not conducive to the continuation of the test. This device can only use dry and hard food, especially for some elderly primate experimental animals or inconvenient speech after modeling Experimental animals that cannot eat dry and hard food at all, and lose the reward factor, the test cannot be carried out;
