Out of body experiences can be created artificially now in the lab. Cool!

Normally, I see what I see and feel what I feel – and that is that. But recently, a university in Stockholm has created a method for consistently fooling the senses in such a way as to trick the person into believing they are out of their own body. We call it “out of body experience” (OOBE). This is SO cool!

People who have come close to death sometimes report what are known as out of body experiences, in which they have seen themselves from somewhere else in the room – usually from above their body. Scientists at the Swedish medical university Karolinska Institutet have now come up with a technique that recreates this sensation in fully conscious healthy volunteers (I told you this was cool!). They hope that this technique will enable them to study the relationship between the body and the ‘self’ in the laboratory environment – allowing for more consistent results.

“The idea for the study came to me several years ago”, says Dr Henrik Ehrsson, research leader in the Department of Clinical Neuroscience. “I wondered what would happen if you moved a person’s eyes to somewhere else in the room. It has been found that the visual perspective is crucial in determining how the ego is experienced.”

The experiments involve the scientists connecting two video cameras placed side by side like robot eyes to a display on the volunteer’s head, one camera for each eye. The cameras are positioned behind the volunteers and aimed at them. The volunteers then see themselves from outside, as if they were someone else looking at them.

But to be able to induce an out of body experience, it is also necessary for the volunteers to sense their “self” outside their physical body. The scientist can induce such a sensation by standing in front of the cameras and poking a point where the chest would be in the perceptual field of the subject – so that it would appear visually as though the scientist is poking the subject’s chest – without the subject seeing that another scientist is simultaneously poking the subject’s actual chest.

“The brain then responds to the hand that touches the illusory body, whereupon the volunteer has a powerful experience of being several metres outside their actual body”, says Dr Ehrsson. “The self has thus moved two metres in space and left the actual body, which instead feels like an empty shell, a doll.”

To prove the illusion scientifically, Dr Ehrsson hit the phantom body of the twelve volunteers with a hammer, and measured the degree of skin sweating in response to the provocation. It was found that the volunteers exhibited the same physiological stress response as when someone’s real body is threatened, but only during the periods when the volunteers were actually experiencing the out of body illusion.

The new tool in the laboratory environment means that it is possible for the first time to undertake scientific research on what we call the self – both fundamental research and applied research – for example in computer science.

“In the future it may be possible not just to control a person in a virtual environment but to become the virtual person, that is to say one’s self will be able to move to virtual persons,” says Dr Ehrsson.
