Description

Technical Field

[0001] The utility model relates to a multimodal behavior analyzer, belonging to the technical field of medical experiments. Background Art

[0002] Many traditional experimental instruments can only perform a single type of behavioral test. For example, the open field test box is only used to evaluate the spontaneous activity and exploratory behavior of animals, but cannot perform other types of behavioral tests. The metal grid experimental instrument can only perform measurements at a single angle, and the detection is not comprehensive enough to perform other experiments. For example, when performing other large and small mouse behavioral analysis experiments, other corresponding experimental instruments are also needed. The functions of the experimental instruments are relatively single and cannot meet the requirements of other large and small mouse behavioral analysis experiments. Moreover, when conducting behavioral tests, the control of the experimental environment is not precise enough, which may affect the accuracy of the experimental results.

[0037] 1) Continuous illumination experiment:

[0038] After removing the rotating handle 4 and the metal grid frame 2, the two wide-angle cameras 9 at opposite corners of the instrument can fully record the experimental process and conditions of large and small mice. The light source provided by the wide-angle cameras 9 is used for continuous illumination experiments, and the light intensity can be adjusted. Five black background plates with magnets are used. Two background plates a10 and two background plates b11 are attached to the four sides of the box 1, and background plate c12 covers the top suspended part to simulate a dark environment and reduce interference from the surrounding environment. After the experiment is completed, the covering black background plates are removed and the drawer 5 is pulled out to remove the experimental mice. Continuous illumination experiments can be used to study the effects of continuous illumination on skeletal muscle mass and exercise endurance in rats after aerobic exercise, or to study the effects of circadian rhythm disorders on hormones in rats. The white background plates a10, b11, and c12 are used in the same way as the black background plates, making it easier to photograph black and white mice while they are inside.

[0039] 2) Open field test

[0040] Similar to the continuous light experiment, four black background boards, two background boards a10 and two background boards b11, are used to completely cover the four sides of the box 1, but the top of the box 1 is not covered. The experimental mice are placed in the box 1, and the wide-angle camera 9 can be used to record the behavioral responses of the rats in the box, such as gait, facial expressions, movements, etc.; the number of grids crossed, central area movement time, grooming number, standing number and other indicators of the mice and rats can be recorded through computer software. After the experiment is completed, the background board b11 on the side of drawer 5 is removed, and the drawer 5 is pulled to take out the mice and rats.

[0041] 3) Multi-angle metal grid experiment

[0042] Install the metal mesh frame 2 in the box 1, connect the connecting seat 402 of the rotating shaft handle 4 to the socket 101, and insert the square shaft 403 into the square hole 201. Place the rat on the metal mesh frame 2. After the rat grasps the wire mesh firmly, manually rotate the handle seats 401 on both sides to flip the metal mesh frame 2 over according to the angle required for the experiment. This can measure the falling time and hanging time of the rat at different angles. The matching measurement system can directly display the data to be measured, which can be used to evaluate the muscle function or nerve regeneration / damage of the rat. After the experiment is completed, pull the drawer 5 below to take it out and clean it.

[0043] 4) Hot plate test

[0044] The bottom plate of the drawer 5 is an intelligent hot plate instrument 8, which is a constant temperature heating device with a temperature adjustment range of 18 to 60°C. When the external power supply is turned on and the bottom of the drawer 5 is heated to a certain temperature, mice and rats will lick their paws, jump, and other behaviors due to pain. The wide-angle camera 9 records the time when the animal shows pain reaction when it is placed on the hot plate, which is the pain domain, an important indicator for evaluating the response to pain; a magnetic charging device 15 is installed between the front side panel of the drawer 5 and the inside of the box 1. If the drawer 5 is pulled out and the interface is separated, the power connection is cut off. If the drawer is completely pushed into the box 1, the intelligent hot plate instrument 8 can be connected to the power supply for the experiment.

[0045] 5) Light and dark box experiment

[0046] After removing the metal grid frame 2 and the rotating shaft handle 4, the partition slot 3 inside the box 1 is placed into the partition board 14 with a semi-elliptical hole 1401, and half of the background board c12 is used as the upper cover to block the light from above. The background board a10 split in half is placed on both sides of the box 1 to block the light on both sides, and a background board b11 blocks the light from the back, which is the dark side; the other side is turned on with additional light, which is the bright side. Use a wide-angle camera 9 to illuminate and record indicators such as the time that mice and rats stay in the light and dark areas, the number of times they cross the semi-elliptical hole 1401, etc., to assess the anxiety level of mice and rats.
