Brain Waves Influence Sense of Body Ownership

Scientists found that the speed of alpha waves in the parietal cortex of the brain affects how well we can tell if a body part is ours.

Faster alpha waves help us feel more precisely that a body part belongs to us, while slower waves make it harder to tell the difference between our body and the outside world.

This was discovered through experiments where people felt a rubber hand as their own when touches were synchronized.

The study could help understand conditions like schizophrenia where people have a disturbed sense of self.
