Animal behavior monitoring system

Abstract

The embodiment of the invention discloses an animal behavior monitoring system. The system comprises a monitoring platform, an image acquisition device, an optogenetics control device, an electroencephalogram fiber coupling acquisition device and a biofeedback device; the monitoring platform comprises three containing spaces and a touch switch, the middle containing space is adjacent to the containing spaces on the two sides separately, the adjacent places are provided with communication holes and barriers, all the barriers move to open / close the corresponding communication holes, food dispensers are placed at the communication holes, animals in the corresponding adjacent containing spaces can take food, the touch switch is installed in the food dispenser in the middle containing space, and after the touch switch is touched, the corresponding barriers move to make the communication holes opened. According to the technical scheme, the strategy of selecting the decision by competing foodrewards of high rewards and low rewards with companions.

Description

technical field [0001] Embodiments of the present invention relate to medical research equipment technology, in particular to an animal behavior monitoring system. Background technique [0002] Decision-making is based on the value of the decision executor's self-evaluation, the economic balance of the interests and costs of preferences among many alternative conditions. Decision-making is a high-level cognitive function of the brain. It is generally believed that the involved cerebral cortex includes 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. A certain reminder. Competitive decision-making is a process in which all parties participating in the competition choose the optimal decision based on considering the strategies that the other party may adopt. The neural mechanism of cortical invo...

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.
