P2.1 Virtual Reality modulates Vestibular Brain Responses Gallagher, M., Dowsett, R. & Ferrè, E.R. Royal Holloway University of London [show_more more="Show abstract" less="Hide abstract"]Virtual reality (VR) has become increasingly popular in the past decade. Key to the user's VR experience are multimodal interactions involving all senses. However, sensory information for self-motion is often conflicting in VR: while vision signals that the user is moving in a certain direction with a certain acceleration (i.e. vection), the vestibular organs provide no cues for linear or angular acceleration. To solve this conflict, the brain might down-weight vestibular signals. Here we recorded participants' physiological responses to actual vestibular events while being exposed to VR-induced vection. We predicted that exposure to a few minutes of linear vection would modulate vestibular processing. Vestibular-evoked myogenic potentials (VEMPs)…
