Out-of-body experience recreated

Experts have found a way to trigger an out-of-body experience in volunteers.

The experiments, described in the Science journal, offer a scientific explanation for a phenomenon experienced by one in 10 people.

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.

The researchers say their findings could have practical applications, such as helping take video games to the next level of virtuality so the players feel as if they are actually inside the game.

Clinically, surgeons might also be able to perform operations on patients thousands of miles away by controlling a robotic virtual self.

Teleported

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.

We feel that our self is located where the eyes are

UCL researcher Dr Henrik Ehrsson 

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 University College London, UK, 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.

In the Swiss experiments, the researchers asked volunteers to stand in front of a camera while wearing video-display goggles.

Through these goggles, the volunteers could see a camera view of their own back - a three-dimensional "virtual own body" that appeared to be standing in front of them.

When the researchers stroked the back of the volunteer with a pen, the volunteer could see their virtual back being stroked either simultaneously or with a time lag.

The volunteers reported that the sensation seemed to be caused by the pen on their virtual back, rather than their real back, making them feel as if the virtual body was their own rather than a hologram.

Volunteers

Even when the camera was switched to film the back of a mannequin being stroked rather than their own back, the volunteers still reported feeling as if the virtual mannequin body was their own.

And when the researchers switched off the goggles, guided the volunteers back a few paces, and then asked them to walk back to where they had been standing, the volunteers overshot the target, returning nearer to the position of their "virtual self".

Dr Henrik Ehrsson, who led the UCL research, used a similar set-up in his tests and found volunteers had a physiological response - increased skin sweating - when they felt their virtual self was being threatened - appearing to be hit with a hammer.

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."

Hmmm , I had one when I was when I was 8 years old , when I was seriously ill ,

so for me it's real ,

All I have to say that for most of us we are where are eyes are.

Well, grandpa,  you right, but I know , there has been several times that my eyes were where they should not have been  :2funny:

Several times? :haha:

My eyes are always where they are supposed to be.

My eyes are always where they are supposed to be.

i'll bet....

Probably true, but where are they aimed?

Places.

We could test the theory

rotflmao, you'd never leave your computer lol

I remember a movie from the 70's, I think it was called " BrainStorm" , they would record there brain waves , and memories, then play them back. Well one of the men doing the research recorded himself in marital pleasure, and looped the tape,(just the peak moment)  he was found a day or so later in sheer Ecstasy, nearly dead, when found, his coworker had to literally make him stop by pulling the headgear (no pun intended, it was on his skull) off of him as he put up a fight.
