System and method for obtaining parameters of animal nystagmus based on VOR (vestibulo-ocular reflex)

Abstract

The invention discloses a system and a method for obtaining parameters of animal nystagmus based on VOR (vestibulo-ocular reflex). The system comprises an animal fixation device, an external stimulation module, an image processing module, a data processing module and two groups of nystagmus image acquisition modules, the two groups of nystagmus image acquisition modules correspond to a left and aright nystagmus images of animals respectively, each group of the nystagmus image acquisition modules comprises an optical eyepiece and an image acquisition device, the animal fixation device is usedto fasten animals to be tested, the external stimulation module is used to apply mechanical stimulus for the animals to be tested, the two image acquisition devices respectively collect the left and right nystagmus images corresponding to the reflex of the optical eyepiece and transfer to the image processing module, the image processing module obtains coordinate data of pupil center, according tothe received nystagmus images, and transfers to the data processing module, and the data processing module obtains nystagmus parameters of the animal to be tested according to the coordinate data ofpupil center. The nystagmus parameters can be obtained accurately through the system and the method, and the system and the method can provide quantitative evaluation of vestibular function with significant evidence.

Description

technical field [0001] The invention belongs to the field of biological neuroscience, and in particular relates to a system and method for acquiring animal nystagmus parameters based on vestibulo-ocular reflex. Background technique [0002] The vestibular system (Vestibule) is the main organ for the human body to perceive body position and environmental changes. It plays a key role in the body's own sense of balance and space, and is an important part of the balance system. Together with the cochlea (part of the auditory system), the vestibular system forms the labyrinth of the inner ear. Depend on figure 1 It can be seen that the vestibular system is composed of the semicircular canal system composed of the horizontal semicircular canal, anterior semicircular canal, and posterior semicircular canal, as well as the balloon and utricle. When people move in space, there are basically only two ways of rotation and parallel movement, so the receptors of the vestibular system a...
