Mouse Vestibulo-Ocular Reflex Tester

The Vestibulo-Ocular Reflex (VOR) testing system for mice can detect the functionality of the mouse's semicircular canals and otolith organs, making it the most advanced equipment in the world for testing the vestibular system of mice. It can evaluate the health status of different parts of the vestibular organ (semicircular canals and otoliths) through the vestibulo-ocular reflex. Moreover, since the receptors of both the vestibular and auditory systems are hair cells, vestibular function testing can also be applied to research on hair cell regeneration and auditory gene therapy.
