Scientists Identify Brain Waves That Define The Limits of 'You'
Summary
Researchers identified a specific alpha-wave frequency in the parietal cortex that influences the sense of body ownership during rubber hand illusion experiments. EEG and transcranial alternating current stimulation (tACS) show that faster alpha waves tighten the body map and enhance detection of timing differences, while slower waves weaken it; this points to a fundamental brain mechanism for multisensory integration. Implications include potential insights into psychiatric conditions like schizophrenia and advances in prosthetics and VR interfaces.
