Closed rotary maze device for animal memory training system

Abstract

The invention discloses a closed rotary maze device for an animal memory training system. The maze device comprises a round box body and a circuit control system. Key technical points of the maze device are that: the bottom of the box body of the maze device is provided with a turntable driven by a motor; the motor is arranged on a central cylinder, and an output shaft of the motor is in fastenedwith the turntable along the axial direction of the central cylinder; the turntable rotates around the central cylinder under the driving of the motor; the periphery of the lower part of a frame of the box body is provided with a plurality of pulleys for supporting the turntable; and a sieve-shaped supporting net is arranged above the turntable. The maze device overcomes the defect of the lateralization in the detection of the conventional maze devices such as a Y-maze and a T-maze. In addition, a device driven by gradient voltage is removed; the maze device effectively prevents animals from finishing experiments by means of smell, and respective disadvantages of a Morris water maze, the Y-maze and a drought maze are weighted; the starlight detection can be performed through program control according to the nocturnal habits of the experimental animals; and the maze device can ensure that the experimental animals are subjected to sensory stimulation in real environment, which is more favorable for acquisition of 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
