Restoration of 3D vestibular sensation in rhesus monkeys using a multichannel vestibular prosthesis

► A multichannel vestibular prosthesis can restore the rhesus 3D vestibulo-ocular reflex. ► Excitation-inhibition response asymmetry is like that of animals with one normal ear. ► Responses are much stronger when multisensory inputs are congruent with each other.
