Another one for science

Reason and rationality was once again strengthened when Experts found a way to trigger an out-of-body experience. Earlier debunking of the ESP qualities of Out of Body Experiences reported on this blog here is now added the following report .

Two teams used virtual reality goggles to con the brain into thinking the body was located elsewhere. The visual illusion plus the feel of their real bodies being touched made volunteers sense that they had moved outside of their physical bodies.

For some, out-of-body experiences or OBEs occurs spontaneously, while for others it is linked to dangerous circumstances, a near-death experience, a dream-like state or use of alcohol or drugs. One theory is that it is down to how people perceive their own body - those unhappy or less in touch with their body are more likely to have an OBE.

But the two teams, from UCL and the Swiss Federal Institute of Technology in Lausanne, believe there is a neurological explanation.

Their work suggests a disconnection between the brain circuits that process visual and touch sensory information may thus be responsible for some OBEs.

Dr Ehrsson said: "This experiment suggests that the first-person visual perspective is critically important for the in-body experience. In other words, we feel that our self is located where the eyes are."
Dr Susan Blackmore, psychologist and visiting lecturer at the University of the West of England, said: "This has at last brought OBEs into the lab and tested one of the main theories of how they occur.
"Scientists have long suspected that the clue to these extraordinary, and sometimes life-changing, experiences lies in disrupting our normal illusion of being a self behind our eyes, and replacing it with a new viewpoint from above or behind."
