The brain's ability to accept virtual wings as real limbs shows how flexible our body awareness can be, useful context for a colleague in neuroscience or prosthetics research following this shift.
Brains Treat VR Wings as Real Limbs Story flow and key facts
A team of researchers in China explored whether humans could learn to 'fly' in virtual reality using motion-controlled feathered wings. Over a weeklong training program, 25 participants used arm flapping and wrist rotation to maneuver through virtual environments, mastering flight tasks like passing through rings and swatting objects. After training, brain scans revealed that the visual cortices—the regions responsible for recognizing body parts—responded to the virtual wings the way they normally do to real limbs, suggesting the brain had incorporated the digital appendages into the body's self-map. This finding highlights the brain's remarkable plasticity and opens possibilities for using VR to train the brain to accept artificial limbs more naturally. While humans won't grow real wings, this research could advance neuroprosthetics and rehabilitation technologies.
Facts
- Researchers at Peking University led by Yanchao Bi and Kunlin Wei conducted a VR flight study published in Cell Reports.
- 25 participants trained over a week to control virtual feathered wings using arm flaps and wrist rotation in VR.
- After training, brain scans showed the visual cortex responded to virtual wings as if they were real body parts.
- The study suggests the brain can quickly integrate artificial extensions into its body map.
