Neural substrates, dynamics and thresholds of galvanic vestibular stimulation in the behaving primate

Abstract

Galvanic vestibular stimulation (GVS) uses transmastoid electrical currents to activate the vestibular system in humans without head movement. Here, the authors apply GVS to monkeys and record the activity of vestibular afferents to both GVS and motion to reveal the neural substrate underlying GVS evoked perceptual, ocular and postural responses.
