Closed rotary maze device for animal memory training system

Abstract

A closed rotary maze for animal memory training system includes a round case (1) and a circuit control system. The bottom of the case (1) is provided with a rotary plate (6) actuated by a motor (4). The motor (4) is installed on a central post, and the output shaft of the motor (4) is fixedly connected with the rotary plate (6) along the axis of the central post so that the rotary plate (6) is rotated around the central post by the action of the motor (4). The lower peripheral of the frame of the case (1) is provided with several pulleys (12) for supporting the rotary plate (6). A screen-like support net (5) is provided on the rotary plate (6). The present maze adopts the design of using a rotary plate to rotate the round case so that the experimental animals need not be put back to starting-point and the whole session of experiment can be completed uninterruptedly. The maze device abandons the configuration of maze being driven by gradient voltage in prior art. The maze is equipped with an automatic flush and drainage system so as to effectively prevent animals from depending on smell to complete a test. The maze is provided with a remote monitor so as to perform detection under control of programs according to living behaviors of the experimental animals at night. A visual stimulation unit and an odor release unit in the maze work simultaneously, such that the experimental animals feel stimulation as if in a real environment, which facilitates acquirement of the experimental data.

Description

technical field [0001] The invention relates to a model related to research and establishment of animal learning and memory behavior training methods, in particular to a closed rotary maze device used in an animal memory training system. It can be applied to the fields of neurophysiology, neuropharmacology and psychology. Background technique [0002] At present, animal behavior experiments are indispensable and important means for studying advanced brain functions and other neurosciences, especially in behavioral medical research such as neurophysiology and neuropharmacology. Among them, the maze test is a classic project of behavioral experiments, and it is one of the most commonly used experiments to study the learning and memory function of rats (or mice), and it is also a commonly used animal model for cognitive drug screening. [0003] In maze tasks, the maze apparatus itself tells the animals what to do (similar to instructions in human experiments). In this task, r...

Problems solved by technology

However, the applicant found that the maze model still has the following deficiencies: the effect of electric shock stimulation is not gentle enough, and the passive driving of gradient voltage is likely to cause damage to experimental animals in varying degrees, and the setting is relatively complicated; in addition, the device is not perfect enough, and the experimental animals The experiment may be completed with the help of smell, and the above shortcomings will affect the experimental results and the accuracy of the experimental data
