技术领域 technical field
本实用新型涉及一种用于动物视觉电生理实验装置中的动物视觉电生理检查台。 The utility model relates to an animal visual electrophysiological examination table used in an animal visual electrophysiological experiment device.
背景技术 Background technique
动物视觉电生理检测是应用电生理仪器测定视网膜被光照射或图像刺激时，在视觉系统中生产的生物电活动，以研究临床上对视觉功能的评估技术。其主要检测过程为：在眼球表面或大脑枕叶区安放电极，同时记录由于闪光刺激激发视网膜和视觉皮层所产生的电信号。 Animal visual electrophysiological detection is the application of electrophysiological instruments to measure the bioelectrical activity produced in the visual system when the retina is irradiated by light or image stimulation, so as to study the clinical evaluation technology of visual function. The main detection process is: placing electrodes on the surface of the eyeball or the occipital lobe of the brain, and simultaneously recording the electrical signals generated by the stimulation of the retina and visual cortex by flash stimulation.
现有技术中，通常是将角膜电极放置于动物球眼表面，来记录视网膜的电位和电流变化。当进行重复多次实验时，由于很难控制动物的眼球位置在视觉生理检测中的位置一致，使检测结果存在误差，导致相关的研究结果与实际存在偏差。 In the prior art, corneal electrodes are usually placed on the surface of the animal's eye to record changes in retinal potential and current. When the experiment is repeated many times, it is difficult to control the position of the eyeball of the animal in the visual physiological test to be consistent, so that there is an error in the test result, which leads to deviations between the relevant research results and the actual situation.
