Device for detecting, analyzing and processing reward operation condition reflection in real time

Abstract

The invention provides a device for detecting, analyzing and processing reward operation condition reflection in real time. The device comprises a computer system and an experiment box, wherein the computer system comprises a computer host, a PCI (programmable communications interface) / CAN (controller area network) card, a graphic card, a display and an experiment control module; the graphic card is used for receiving video signals of a camera and transmitting the video signals to the computer host for processing; the display is connected with the computer host and is used for displaying experiment data; and the experiment control module is used for setting a reward experiment mode and parameters, receiving and processing the video signals and counting, recording and displaying the experiment data. With the adoption of the device for detecting, analyzing and processing the reward operation condition reflection in real time, various best experiment conditions are set according to experiment purposes; the experiment data and statistic analysis can be automatically given; the interference of external light sources on the experiment can be avoided; and the repeatability of the experiment is guaranteed.

Description

technical field [0001] The invention belongs to an animal experiment device, in particular to a real-time detection, analysis and processing device for rewarding operant conditioned reflex. Background technique [0002] Reward operant conditioning is achieved by applying a variety of complex unconditioned stimulus signals, such as inducing different colors of light, and using substances that can cause reward effects (food, sugar water, and alcohol) as conditioned stimulus signals. , Actively explore, gain experience, consolidate memory and reproduce, and finally make the animal learn to actively perform the operation of pressing the lever, forming a conditioned reflex for obtaining reward substances. Because the behavioral evaluation technology produced by this reward effect has little stimulation to the animal's behavior and psychological damage, it can be combined into a variety of complex signal tasks. A major behavioral testing method. [0003] At present, the reward-o...

AI Technical Summary

Problems solved by technology

[0003] At present, the reward-operated conditioned reflex testers used abroad, such as the reward-operated experimental equipment developed by Bioseb, Panlab, and TSE, all adopt modular design, but do not use computer vision technology. The signal combination obtained during the test is simple and easy to operate. The pedal is single, and the data information obtained in the test can only obtain the number of pedal operations, the number of rewards obtained, etc., resulting in fewer indicators for evaluating learning and memory obtained during the test, which affects the accuracy of the test results
