Scientists found the brain rhythm that makes your body feel like yours
- Latest study links faster parietal alpha waves to sharper sense of body ownership in humans.
- Faster alpha rhythms improve timing between sight and touch, strengthening ownership.
- Slower alpha frequencies widen the temporal binding window, blurring self vs. environment.
- Non-invasive brain stimulation altered alpha speed and changed body ownership perception.
- Study involved 106 participants and used EEG, stimulation, and modeling to test body ownership.
- Findings may help design better prosthetics and more immersive virtual reality.
- Research ties alpha frequency to how precisely the brain evaluates timing of sensory input.
- The work was a collaboration between Karolinska Institutet and Aix-Marseille Université.
- Funding for the study came from ERC, Swedish Research Council, VINNOVA, StratNeuro, and A*Midex.
