Acquiring system of vestibular evoked potentials of animal

Abstract

The invention discloses an acquiring system of vestibular evoked potentials of an animal. The acquiring system of the vestibular evoked potentials of the animal comprises an external stimulation device, a multichannel electrode resistor array and a neural signal recorder; the multichannel electrode resistor array is arranged on the head of the detected animal, and electrodes on the multichannel electrode resistor array extend to vestibular nucleus positions in the cranium of the detected animal, and are fixed; a signal input end of the neural signal recorder is electrically connected with a signal output end of the multichannel electrode resistor array; and the detected animal is fixed to the external stimulation device, the external stimulation device applies vibration stimulation on thedetected animal, and the multichannel electrode resistor array collects vestibular potential signals, of the detected animal, evoked by vibration stimulation, and delivers the collected vestibular potential signals to the neural signal recorder for recording and display. Compared with a traditional mode of evoking vestibular potentials through electrical stimulation, the acquiring system of the vestibular evoked potentials of the animal is more liable to be controlled, and interference of external current on potential recording is reduced.

Description

technical field [0001] The invention belongs to the technical field of nerve signal acquisition, and in particular relates to an acquisition system of animal vestibular evoked potential. 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, 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 also perceive these two kinds of movements. Among them...
