Problems solved by technology

The existing ones that can automatically record the behavioral activities and related data of experimental animals are relatively expensive, and during the experiment, rats will adopt various methods to avoid electrical stimulation, which makes it impossible to test the learning and memory experiments of rats. Standing on legs, climbing on the side wall of the Y-arm and walking along the edge, or directly escaping from the ordinary Y-arm plexiglass device, these will lead to errors in the experimental results or the termination of the experiment

Embodiment Construction

[0015] exist figure 1 As shown, the three power grids (2a), (2b), (2c) are connected in parallel, and three switches (7e), (7f), (7g) are used to control the current independently, and the three light bulbs (4a), (4b), (4c) are connected in parallel, and the switches (7a), (7b), (7c) are used to control the current independently, and the triangular grid 9 uses the switch (7d) to control the current independently, and then the three grids (2a) , (2b), (2c) and the three light bulbs (4 a), (4b), (4c) and the triangular grid (9) are in parallel relationship. In order to ensure the safety of the experimental animals, the voltage of the power grid (2a), (2b), (2c) and the triangular power grid (9) is controlled at 50V-70V DC voltage, and the light bulb (4) is controlled at a normal 220V voltage.

[0016] Such as figure 2 As shown, the power grids (2 a), (2b), (2c) are respectively fixed on the bottom and side walls of the three independent arms of the experimental device of the ...

Abstract

The invention relates to a device for testing study memory performance of rats, and belongs to the technical field of experiment tools. A maze experimental device is Y-shaped and comprises three independent supporting arms and a central triangular region which is formed by commonly connecting one end of three slot-shaped independent supporting arms, wherein a cover matched with the shape of the independent supporting arm is formed on each independent supporting arm; dense grids are paved at the slot-shaped bottom and the side wall of each independent supporting arm; the grids at the bottom and the side wall of each independent supporting arm share one power line and are independently controlled by one switch; a triangular grid is arranged at the slot-shaped bottom of the central triangular region, and the grid of the central triangular region is independently controlled by one switch; and an organic glass baffle is arranged at end ports of slot-shaped inside of the other end of each independent supporting arm, a bulb is mounted behind each organic glass baffle, and the bulbs (4a, 4b, 4c) in each independent supporting arm are controlled by one switch.

Description

technical field [0001] The invention relates to a device for testing the learning and memory ability of rats, which belongs to the technical field of experimental equipment. Background technique [0002] In the study of learning and memory pharmacology, anti-aging drugs, and new drug nervous system pharmacology and toxicology, it is necessary to observe and analyze the changes in the learning, memory or spatial cognition of experimental animals, which usually requires the animals to be placed in the experimental environment to complete a certain the behavior of. At present, the experimental devices for testing the learning and memory ability of rats include water maze experimental devices, eight-arm maze experimental devices, sixteen-arm maze experimental devices, traditional Y-arm electronic maze experimental devices, and so on. [0003] The traditional Y-arm maze experimental device is an experiment in which the experimental animals (rats) are starved to reduce their body...
