The scientist gives Grace directions on using the experimental "God Helmet"

Persinger reports that many subjects have reported "mystical experiences and altered states" while wearing the God Helmet.

The theoretical basis for the God helmet, especially the connection between temporal lobe function and mystic experiences, has also been questioned.

Magnetic stimulation of the brain, as with the God helmet developed by Michael Persinger.

Reports by participants of a "sensed presence" while wearing the God helmet brought public attention and resulted in several TV documentaries.

Grace says that, although it's probably manufactured from her "God Helmet," she finds comfort in her visions of Tom after his death.

During the 1980s he stimulated people's temporal lobes artificially with a weak magnetic field to see if he could induce a religious state (see God helmet).

Experimental attempts to replicate effects claimed to occur with use of commercial versions of the God helmet have found no difference whether the device was on or off.

Persinger has even created a "God helmet" which purportedly can evoke altered states of consciousness through stimulation of the parietal and temporal lobes.

The God Helmet was not specifically designed to elicit visions of God, but to test several of Persinger's hypotheses about brain function.

The God Helmet experiments were also intended, though not specifically designed (see above), to validate the idea that religious and mystic experiences are artifacts of temporal lobe function.

The "God Helmet" refers to an experimental apparatus originally called the "Koren helmet" after its inventor Stanley Koren.

Persinger and Koren designed the God Helmet in an attempt to create conditions in which contributions to the sense of self from both cerebral hemispheres is disrupted.

The Webb Brothers are now based in Los Angeles and have recorded several mini-projects, such as 'Music From The God Helmet'.

Grace, although skeptical (when asked what the helmet is called, she mockingly answers, "The God Helmet"), is mesmerized by the feelings she experiences while using the device.

Neuroscientist Michael Persinger has studied the role of the right temporal lobe in the feeling of a sensed presence and god beliefs by stimultation with a so-called God helmet.

Persinger's claims regarding the effects of environmental geomagnetic activity on paranormal experiences have not been independently replicated and, like his findings regarding the God helmet, may simply be explained by the suggestibility of participants.

Neither the God Helmet, nor technologies derived from it, are examples of transcranial magnetic stimulation (TMS), which uses magnetic fields on the order of one million times stronger than those used in Persinger's lab.

Michael Persinger stimulated the temporal lobes of the brain artificially with a magnetic field using a device nicknamed the "God helmet," and was able to artificially induce religious experiences along with near-death experiences and ghost sightings.

Commercial versions of the God helmet, Octopus and associated devices are sold by Persinger's research associate Todd Murphy, and he reports that his devices are able to modulate emotional states in addition to enhancing meditation and generating altered states.

During the 1980s Michael Persinger stimulated the temporal lobes of human subjects with a weak magnetic field using an apparatus that popularly became known as the "God helmet" and reported that many of his subjects claimed to experience a "sensed presence" during stimulation.

The second experimental hypothesis was that when communication between the left and right senses of self is disturbed, as they report it is while wearing the God Helmet, the usually-subordinate 'self' in the right hemisphere intrudes into the awareness of the left-hemispheric dominant self, causing what Persinger refers to as "interhemispheric intrusions".
