An animal behavior monitoring system

Abstract

The embodiment of the present invention discloses an animal behavior monitoring system, which includes: a monitoring platform, an image acquisition device, an optogenetics control device, an EEG optical fiber coupling acquisition device, and a biofeedback device; wherein, the monitoring platform includes three accommodating Space and touch switch, the middle accommodation space is adjacent to the accommodation spaces on both sides respectively, and communication holes and blocking pieces are arranged in the adjacent places, and the movement of each blocking piece makes the corresponding communication holes be opened / closed, and the food placer is placed at the communication holes , for the animals in the corresponding adjacent accommodation space to feed. The touch switch is installed at a food place in the middle accommodation space. After the touch switch is touched, the corresponding blocking member moves to open the communication hole. Through this The technical solution invented to realize the strategy of choosing decision-making through competitive high-reward and low-reward food rewards with peers.

Description

technical field [0001] Embodiments of the present invention relate to medical research equipment technology, and in particular, to an animal behavior monitoring system. Background technique [0002] Decision-making is an economic balance of benefits and costs based on the decision-maker's self-assessed value and preference among a number of alternative conditions. Decision-making is a high-level cognitive function of the brain, and it is generally believed that the cerebral cortex involved include the prefrontal cortex, cingulate gyrus, and orbitofrontal cortex. The study of the brain mechanism of decision-making behavior and related neural circuits is of great significance for revealing the cognitive function of the brain, and at the same time, it is of great significance for the treatment of mental diseases (major depression, ADHD, schizophrenia, etc.) Certain hints. Competitive decision-making is a process in which the parties involved in the competition choose the opti...

Problems solved by technology

The active operation box is airtight, the behavior of animals is not easy to observe, and the behavior of animals is limited; the use of the active operation box is not convenient to take later drugs or light, electricity, and optogenetics intervention on animals; animals are generally not biased in their natural state. Take the initiative to operate the experiment; the active operation box can only judge the reaction latency of the animal by analyzing the time of pressing the pedal twice, but it cannot make a correct judgment on the state and time of the animal between the two choices, that is, the animal chooses to eat delicious food It is impossible to determine the reaction latency between eating the coarse grain and choosing to eat the coarse grain; comparing the decision-making behavior of the two animals, it is necessary to compare the amount of coarse grain and refined grain consumed by the animal, so it is necessary to weigh the weight of coarse grain and refined grain before and after the experiment , often in the experiment, because the animals eat the food in pieces, it is often scattered, so the operation is more troublesome and wastes the time of the experimenter

The traditional T-maze is only selected based on the difference between the left and right conditions of the position. After reaching a certain accuracy rate, other molecular, pharmacological or genetic operations are performed, which requires a long-term training process.
