Abstract

The invention discloses a noise Y labyrinth device, which comprises a labyrinth and a control unit. The labyrinth comprises a bottom plate, partition plates, a top cover and arms, the arms comprise an outer arm and an inner arm, and the partition plates comprise an inner partition plate and an outer partition plate; an indicator lamp and a sound stimulation generator are disposed at an outer portof the outer arm, an infrared scanning device is disposed at an inner port of the outer arm, the indicator lamp, the sound stimulation generator and the infrared scanning device are connected with the control unit via a bus, and the other end of the control unit is connected with a first signal lamp and a second signal lamp which are used for experimenters to observe; and the top cover covers above the inner arm, the outer arm and the partition plates. The invention further discloses a control method for the noise Y labyrinth device. Shortcomings that a traditional electric Y labyrinth severely injures animals, wastes time and labor during working, and the like are overcome, noise is used as a stimulation source, simple and labor-saving operation is realized, influences of human factors are reduced, and furthermore, accuracy of experimental results is improved.

Description

technical field [0001] The invention relates to an animal experiment device and a control method thereof, in particular to a Y-maze device using noise as a stimulus source and a control method thereof. Background technique [0002] Mazes have been used in experiments for centuries. The Y maze is widely used in animal behavior experiments. As a device for evaluating the spatial memory ability of rodents, it plays an important role in neurophysiology and neuropharmacology. The classic Y maze mainly uses repeated unconditioned reflex strengthening training to establish conditioned reflex as the basic principle, and generally uses electrical stimulation. However, there are still some deficiencies in the design of the traditional electric Y maze, for example: (1) Electrical stimulation can easily cause limb damage to mice, and the appropriate intensity is not easy to control. (2) Electrical stimulation can easily cause increased defecation in mice, and feces often lead to short...
