Profound bilateral loss of vestibular hair cell function can cause chronically disabling loss of
balance and inability to maintain stable vision during head and body movements. We have
previously shown that chinchillas rendered bilaterally vestibular-deficient via intratympanic
administration of the ototoxic antibiotic gentamicin regain a more nearly normal 3-
dimensional vestibulo-ocular reflex (3D VOR) when head motion information sensed by a
head-mounted multichannel vestibular prosthesis (MVP) is encoded via rate-modulated …
