summary

A scalable MR‑compatible VR platform recreates the scanner room and matches real posture and appearance to induce embodiment and presence while lying in a 3T scanner with ~110 dB noise. Hardware includes VisualSystem HD stereoscopic goggles with eye‑tracking, Qualisys Oqus 500+ cameras for motion capture, and homemade tennis‑ball hand controllers with three buttons. Pilot results show <1 voxel average head motion, <10% data loss, stronger body ownership and agency, and replicated perceptual, motor and cognitive fMRI/behavioral effects.
