Embodiment Construction

[0018] Embodiments of the present invention (taking the rat Y maze as an example):

[0019] The automatic maze device is composed of a maze main body, an infrared detector and a control circuit, a data acquisition card with a PCI interface of a program-controlled door and a computer control program.

[0020] (1) The main body of the maze is attached figure 1 As shown in (A), the main body of the maze is a "Y"-shaped maze connected by 3 channels, which consists of an initial arm (70 cm in length) and two symmetrical selection arms (42 cm in length). The included angle between any two passages of the maze is the same, 120°. Each channel has the same width and the same channel wall height, which are 14 cm and 20 cm, respectively. In order to provide the space required for the downward opening of the program-controlled door and the installation space required for the corresponding power unit 3 motors on the bottom of the labyrinth and ensure the strength of the labyrinth struct...

Abstract

The invention discloses a rat / mouse labyrinth automatic training device, belonging to the technical field of animal behaviors and neuroelectrophysiology experiments. The device comprises a main labyrinth body, an infrared detector, a program control door system which is opened downwards vertically, a PCI (programmable communication interface) interface data acquisition card and a computer control program. A core technology lies in the effective implementation of the program control door system. The device realizes automatic rat / mouse labyrinth training and enables the electrophysiological record of animals carrying out labyrinth task operations to be possible. The program control door has concise structure and stable and reliable work, and the design of opening downwards vertically avoids the blocking and the winding of connecting lines during wired electrophysiological recording; and the invention maintains the conciseness and the smoothness of an original labyrinth to a maximum extent.

Description

technical field [0001] The invention belongs to the experimental fields of animal behavior and neuroelectrophysiology, and in particular relates to an automatic labyrinth training device for rats and rats. Background technique [0002] A variety of maze models (such as Y / T maze, plus maze, and eight-arm maze) are the basic means for studying learning and memory in rodents. It is also commonly used in some other fields, such as the identification of cognitive functions in genetically manipulated animals, and the screening of cognitive drugs. [0003] In the past, when animals were trained in this type of maze, artificial training methods were often used. For example, the delayed alternating task of the rat Y maze is the most commonly used model for testing the working memory ability of rats. In the past, during task training, the experimenter had to hold a baffle to confine the rats in the starting area, and then remove the baffle after a specified delay period, allowing th...
