Description

Technical Field

[0001] The present invention relates to the technical field of animal foraging behavior experiments, and in particular to a detection device and method for animal foraging behavior decision-making. Background Art

[0002] Fear is an adaptive mechanism that drives animals away from dangerous situations and creatures. At the same time, foraging is also a basic need of animals for survival. Studies have found that when faced with the threat of predators, animals' foraging will be limited to smaller places and shorter times. Animals will perform some selective behaviors in this situation. The neurophysiological basis behind these selective behaviors is still largely unknown. At the same time, analyzing the fear behavior of animals will contribute to the development of brain cognitive science and will also have a certain promoting effect on the treatment of mental system diseases (such as depression, schizophrenia, and bipolar disorder).

[0003] There have been studies on the brain neural activities of small animals under this kind of conflict decision-making. Most of them set up props in a box to intimidate the animals. However, the current equipment and the intimidation steps of predators require manual control, such as controlling the sudden appearance of props. When manually controlling, the props will be triggered when the animal just appears or after foraging. It is not easy to control the timing of intimidating the animal, and thus it is impossible to accurately simulate the foraging behavior of animals under fear, resulting in low authenticity and accuracy of the experiment.

[0004] In view of this, the existing technology still needs to be improved and developed. Summary of the invention

[0024] In view of the shortcomings of the prior art, this embodiment provides a detection device and method for animal foraging behavior decision-making, which can be specifically referred to as follows: As attached Figure 1As shown, a detection device for animal foraging behavior decision-making includes a detection box 1, an active switch door 2, a scare robot 3, a position detection device and an in vivo multi-channel electrophysiological recording electrode; the detection box 1 has a cavity inside, and the cavity is divided into a nesting area 11 and an exploration area 12, the nesting area 11 is used to place experimental animals; food to be taken 6 is placed in the exploration area 12, and the food to be taken 6 is used to lure experimental animals to forage; an active switch door 2 is provided between the nesting area 11 and the exploration area 12, and the active switch door 2 is provided on the side wall of the detection box 1, and the nesting area 11 and the exploration area 12 can be separated or connected by the active switch door 2 to facilitate experiments; the exploration area 12 is also provided with a scare robot 3 and a position detection device, the scare robot 3 is located on the side of the food to be taken 6 away from the nesting area 11, and the scare robot 3 is located on the side of the food to be taken 6 away from the nesting area 11, and the scare robot 3 is located on the side of the nesting area 11 away from the scare robot 3.

The position detection device is used to detect the position of the experimental animal. After detection, the intimidation robot 3 sends a start signal to the intimidation robot 3, and the intimidation robot 3 starts and intimidates the experimental animal, wherein the intimidation robot 3 has intimidation methods such as action, sound and light; an in vivo multi-channel electrophysiological recording electrode is set in the body of the experimental animal, and the in vivo multi-channel electrophysiological recording electrode is connected to an external data collector through a wire, and the data collector is connected to a computer through a wire, and the experimenter can view the collected behavioral data and neural activity data in real time on the computer.

[0025] In the initial state, the experimental animal is located in the nesting area 11, and the movable switch door 2 is in a closed state, and the experimental animal can only move in the nesting area 11; there is enough water and food below the normal amount (the normal amount is the amount of food required by the experimental animal every day) placed in the nesting area 11. After a predetermined time, the movable switch door 2 can be opened. At this time, the experimental animal is in a hungry state and will forage for food, and the exploration area 12 is placed at a certain distance from the movable switch door 2. The experimental animal will move towards the food 6. During the movement, the experimental animal will trigger the position detection device, and the position detection device will send a start signal to The threatening robot 3 moves toward the food to be taken 6 and simultaneously makes threatening movements to scare the experimental animal. After being threatened, the experimental animal will return to the nesting area 11, and the threatening robot 3 will return to its initial state. At this time, the experimental animal completes a foraging behavior. After the foraging behavior is repeated ten times and the experimental animal returns to the nesting area 11 (during the process of repeating the foraging behavior ten times, the active switch door 2 is in the open state), the active switch door 2 can be closed, and then the threatening robot 3 is taken away, and then the active switch door 2 is opened, and the neural activity data of the experimental animal is obtained by using the in vivo multi-channel electrophysiological recording electrodes to complete the experiment.

After implantation, the experimental animals are allowed to recover for 7-10 days before the experiment is carried out. During the entire experimental process, the infrared camera is turned on simultaneously. The entire experiment is divided into three stages. The first stage is the fasting stage, the second stage is the habit formation stage, and the third stage is the foraging decision stage. During the third stage, the in vivo multi-channel electrophysiological recording electrodes are required to record the neural activity data of the experimental animals. The first stage lasts for 3 days. During this time, the experimental animals are fed less than the normal amount of food every day, so that the experimental animals are in a hungry state. At the same time, food 6 to be taken will also be placed in the exploration area 12 to facilitate subsequent experiments.
