March, 2008:

I’m taking part in a vanguard experiment on the physical sources of spiritual consciousness, the current work-in-progress of Michael Persinger, a neuropsychologist at Canada’s Laurentian University in Sudbury, Ontario. His theory is that the sensation described as “having a religious experience” is merely a side effect of our bicameral brain’s feverish activities. Simplified considerably, the idea goes like so: When the right hemisphere of the brain, the seat of emotion, is stimulated in the cerebral region presumed to control notions of self, and then the left hemisphere, the seat of language, is called upon to make sense of this nonexistent entity, the mind generates a “sensed presence.”

Persinger has tickled the temporal lobes of more than 900 people before me and has concluded, among other things, that different subjects label this ghostly perception with the names that their cultures have trained them to use – Elijah, Jesus, the Virgin Mary, Mohammed, the Sky Spirit. Some subjects have emerged with Freudian interpretations – describing the presence as one’s grandfather, for instance – while others, agnostics with more than a passing faith in UFOs, tell something that sounds more like a standard alien-abduction story.

It may seem sacrilegious and presumptuous to reduce God to a few ornery synapses, but modern neuroscience isn’t shy about defining our most sacred notions – love, joy, altruism, pity – as nothing more than static from our impressively large cerebrums. Persinger goes one step further. His work practically constitutes a Grand Unified Theory of the Otherworldly: He believes cerebral fritzing is responsible for almost anything one might describe as paranormal – aliens, heavenly apparitions, past-life sensations, near-death experiences, awareness of the soul, you name it.
