Our bodies may help us remember our lives, fixing experiences in place. By using virtual reality, scientists can make people feel like they're outside their own bodies. And when they do, the brain struggles to remember what happened.
The phenomenon is a bit like the disembodied sensation that some people have with post-traumatic stress disorder or schizophrenia, according to Loretxu Bergouignan, a neuroscience researcher at the Karolinska Institute in Stockholm, and lead author of the study. You might even compare it to an extreme form of daydreaming.
