Scientists recreate ghosts and strange phenomenon in the lab

Neuroscientists have succeeded in creating 'ghosts' in the laboratory by tricking the brains of test subjects into feeling an unexpected 'presence' in the room.

The spooky experiment which conjured up a ghostly illusion in the laboratory has proved once and for all that it's only our mind playing tricks.

The invisible, creepy presence reported by so many people over the centuries is just a set of mixed-up signals in the brain, the researchers say.

The sensation was re-created by researchers using a robot to interfere with the sensory signals in the brains of blindfolded volunteers.

Under normal circumstances the brain is able to form a unified self-perception, but lead researcher Olaf Blanke explained that when this malfunctions the brain creates a second representation of its body.

'Most of the research predicts that we cannot tickle ourselves because our brain precisely predicts of one hand, of my hand, touching my body or touching one or another position.

However, if this is not fully integrated because I'm doing it or if I cannot correctly predict because somebody else were to touch me; in those cases of uncertainty, very often in those cases of double touch, the response is that you feel ticklish or tickled by somebody else,' said Blanke who is leading the research at the Swiss Federal Institute of Technology in Lausanne, Switzerland (EPFL).

The findings appear to explain the common experience people have of feeling an unseen presence, even a guardian angel, demon or apparition stalking their movements.
