Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical research, in particular to an experimental device for harm-avoiding cooperative behavior. Background Art
[0002] Cooperation is a widespread social behavior that is essential for the survival of many species, including humans. The study of cooperative behavior in mice can help promote the study of a variety of diseases, such as autism and Alzheimer's disease. Although mice show limited cooperative abilities in certain behavioral paradigms, exploring their cooperative behavior and its underlying neural mechanisms remains an interesting question.
[0003] According to the motivation of mice's cooperative behavior, it can be divided into two categories: profit-seeking cooperative behavior and harm-avoiding cooperative behavior. At present, most experimental devices use the profit-seeking motivation of mice, usually by fasting or water deprivation, so as to stimulate the motivation of mice to seek profit. In addition, the existing experimental devices have a long initial learning time, because mice can only get rewards when they touch buttons or levers in accidental activities. The experimental devices for harm-avoiding cooperative behavior currently used are too complicated, which exceeds the learning ability of mice and causes great harm to mice, and the training time required is too long. For example, two mice must press the button at the same time to avoid electric shock. This device obviously exceeds the learning ability of mice and will cause harm to mice, and even the mice will become numb. Utility Model Content

[0031] See also Figure 1 , Figure 2 The utility model provides an experimental device for avoiding harm cooperative behavior, comprising a water tank 1, in which a heating device is arranged.
[0032] The round table 8 is placed in the water tank 1, a transparent column 9 is installed at the center of the top of the round table 8, a spring 10 is connected to the center of the bottom of the round table 8, and the bottom of the spring 10 is fixed to the bracket 11. The transparent column 9 is used to prevent the two mice from running directly to the center of the round table 8 without cooperative behavior. In this embodiment, a sticky hook 13 is installed at the center of the bottom of the round table 8, and the sticky hook 13 is connected to the spring 10. The sticky hook 13 is used to fix the spring 10 but is convenient for disassembling and replacing the spring 10.
[0033] In this embodiment, the water tank 1 is a glass product, and the length, width and height are 60cm, 50cm and 40cm respectively. In order to ensure that the round table 8 can be placed normally in the water tank 1, the round table 8 can be made of light material, so that it can be supported by the spring 10. The design idea of the device is: put two mice in the water of the water tank 1, place them diagonally, and gradually heat the water. The mice will climb onto the round table 8 driven by the instinct of seeking benefits and avoiding harm. The round table 8 is supported by the spring 10 and the sticky hook 13. Only when the two mice reach balance on the round table 8 can the round table 8 be guaranteed not to tilt. If the two mice do not reach balance on the round table 8, it will cause the round table 8 to tilt and cause the mice to fall into the water. The mice will find the balance point after several attempts and record the time. Then gradually reduce the stiffness coefficient of the spring 10 and repeat the above steps to gradually increase the cooperation consciousness of the mice.
[0034] During the experiment, the truncated table 8 was placed in the water tank 1, water was added to the water tank 1 until the water level was 1-2 cm from the bottom of the truncated table 8, the water was heated by a heating device, and then two mice were put into the water, and the time it took for the mice to reach balance on the truncated table 8 was recorded. The experiment was repeated again by gradually replacing the spring 10 with a reduced stiffness coefficient to increase the cooperation awareness of the mice.

[0040] Optionally, a thermometer 7 is provided on the side wall of the water tank 1, and the thermometer 7 is used to measure the temperature of the water. In this embodiment, in order to avoid the water temperature being too high and causing harm to the mice, the water temperature can be adjusted by observing the scale of the thermometer 7. In other embodiments, a constant temperature water tank can also be used, and a non-constant temperature water tank or a constant temperature water tank can be used. The water temperature in the water tank 1 is preferably controlled at 23-25°C.
[0041] Optionally, the heating component 5 is a heating wire or a heating copper tube.
[0042] In this embodiment, the heating component 5 is preferably a heating wire or a heating copper tube, and other heating components may also be selected, which are not listed here one by one.
