God helmet
From Wikipedia, the free encyclopedia
The term God Helmet refers to a controversial experimental apparatus in neurotheology. The apparatus, placed on the head of an experimental subject, stimulates the brain with magnetic fields. Some subjects reported experiences similar to spiritual experiences.[1] The leading researcher in this area is Michael Persinger. Persinger uses a modified snowmobile helmet or a head-circlet device nicknamed the Octopus that contain solenoids which create a weak but complex magnetic field over the brain's right-hemisphere parietal and temporal lobes. Persinger reports that at least 80 per cent of his participants experience a presence beside them in the room, which they variously say feels like God or someone they knew who had died.
There is controversy as to whether Persinger measured actual effects or just led his subjects into believing they experienced an electronically-induced epiphany. In December 2004 Nature reported that a group of Swedish researchers, replicating the experiment under double-blind conditions, was not able to verify the effect. Susan Blackmore, experimental psychologist and experienced researcher of "paranormal" experiences, was reluctant to give up on the theory just yet. She said "When I went to Persinger's lab and underwent his procedures I had the most extraordinary experiences I've ever had....I'll be surprised if it turns out to be a placebo effect." Persinger, however, takes issue with the Swedish attempts to replicate his work. "They didn't replicate it, not even close," he says. He argues that the Swedish group did not expose the subjects to magnetic fields for long enough to produce an effect. He also stresses that some of his studies were double blinded.
A report of an experiment on Richard Dawkins in 2003 said:
- The experiment is based on the recent finding that some sufferers from temporal lobe epilepsy, a neurological disorder caused by chaotic electrical discharges in the temporal lobes of the brain, seem to experience devout hallucinations that bear a striking resemblance to the mystical experiences of holy figures such as St Paul and Moses.
Dawkins was reported not to have experienced a religious feeling. The report said:
- Dr Persinger has explained away the failure of this Transcranial Magnetic Stimulator. Before donning the helmet, Prof Dawkins had scored low on a psychological scale measuring proneness to temporal lobe sensitivity.
