Out-of-Body Experience? Your Brain Is to Blame

Sandra Blakeslee | October 3

NYT - They are eerie sensations, more common than one might think: A man

describes feeling a shadowy figure standing behind him, then turning

around to find no one there. A woman feels herself leaving her body and

floating in space, looking down on her corporeal self.

Such experiences are often attributed by those who have them to paranormal

forces.

But according to recent work by neuroscientists, they can be induced by

delivering mild electric current to specific spots in the brain. In one

woman, for example, a zap to a brain region called the angular gyrus

resulted in a sensation that she was hanging from the ceiling, looking

down at her body. In another woman, electrical current delivered to the

angular gyrus produced an uncanny feeling that someone was behind her,

intent on interfering with her actions.

The two women were being evaluated for epilepsy surgery at University

Hospital in Geneva, where doctors implanted dozens of electrodes into

their brains to pinpoint the abnormal tissue causing the seizures and to

identify adjacent areas involved in language, hearing or other essential

functions that should be avoided in the surgery. As each electrode was

activated, stimulating a different patch of brain tissue, the patient was

asked to say what she was experiencing.

Dr. Olaf Blanke, a neurologist at the 蒫ole Polytechnique F閐閞ale de

Lausanne in Switzerland who carried out the procedures, said that the

women had normal psychiatric histories and that they were stunned by the

bizarre nature of their experiences.
