A purpose-designed VR head-mounted display enables wearable OPM-based MEG with magnetic flux density two orders of magnitude lower than consumer-grade alternatives, supporting whole-brain recordings during movement.
- Why it matters: Naturalistic, immersive experiments require VR-compatible MEG, but magnetic interference from typical head-mounted displays has prevented reliable whole-brain measurements.
- What they did: The team built and validated an HMD with minimal ferromagnetic material, then used phantom tests and perceptual and cognitive benchmark tasks to assess stimulus-evoked activity at sensor and source levels.
- The result: Robust neuronal activity was detected across many brain regions, including visual, motor, and prefrontal cortices, enabling whole-brain MEG in immersive behaviors despite remaining noise peaks.
