Scientists identify brain waves that define the limits of 'you'

Scientists linked specific brain waves in the parietal cortex to the sense of body ownership.
The rubber hand illusion was used to study how the brain integrates sensory input to create a sense of self.
Alpha wave frequency in the parietal cortex correlated with participants' ability to detect timing discrepancies in touch.
Faster alpha waves made individuals more sensitive to small timing differences, reinforcing body ownership.
Slower alpha waves blurred the boundary between self and external objects, making fake hands feel more real.
Non-invasive brain stimulation altered alpha wave frequency, directly affecting the sense of body ownership.
Findings may help understand psychiatric conditions like schizophrenia and improve prosthetic or VR technology.
