A wearable visual stimulation device for mobile experimental animals

Abstract

The invention relates to a wearable sight simulation device for a moveable experiment animal, which comprises a device body and a supporting iron frame stage; the bottom end of the device body is provided with a copper screen, and the upper part of the copper screen is provided with a fixing cross rod; the outer end of the fixing cross rod is connected with a fixing nut, and the upper part of thefixing cross rod is fixed with a fixing tripod; the bottom end of the fixing tripod is equipped with a middle nut, the upper part of the fixing tripod is provided with a fixing base, and the front endof the top part of the fixing base is provided with a current input line fixing joint; the upper part of the current input line fixing joint is equipped with a current input connection line, left andright ends of the top part of the fixing base are provided with bearings. The wearable sight simulation device has the beneficial effects that the wearable sight simulation device for the moveable experiment animal is provided with the fixing base; through the current input line fixing joint, the current input connection line can be fixed; meanwhile, a light source fixing rod can be rotated through the bearing rotation, thus the light source fixing rod is convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of rodent experimental devices, in particular to a wearable visual stimulation device for mobile experimental animals. Background technique [0002] Animal experiments refer to scientific research using animals in laboratories to obtain new knowledge about biology, medicine, etc. or to solve specific problems. Animal experiments must be conducted by trained personnel with research degrees or professional technical capabilities Or under its guidance, the light source can be used to stimulate the rodent's eyes during the experiment, so as to obtain the required experimental parameters. [0003] Existing mobile experimental animals use a wearable optical stimulation device to fix the position of the light source. For freely moving animals, the intensity of light stimulation they receive will vary with the orientation of the head and face and the angle between the light source and the eyeball. In order to allow...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a wearable visual stimulation device for mobile experimental animals to solve the problem of the fixed position of the existing light-emitting source proposed in the above-mentioned background technology. The intensity will change with the orientation of the head and face and the angle between the light source and the eyeball. In order to allow freely moving animals to receive sufficient light stimulation, it is necessary to increase the light intensity, which will inevitably lead to the inevitable images of other objects in the experimental field. As seen by the animal, the effect of the change in neural activity induced by the eventual light stimulus is erratic, either by the light stimulus alone, by the object illuminated by the light, or by both In addition, the weight of the general device is relatively large. Since the animal cannot bear the weight of the eye stimulation device, the head of the animal can only be fixed in most cases to reduce the burden on the head and neck, and this fixed head will strengthen the animal's problems that greatly limit an animal's ability to participate in a variety of complex behavioral tests
