BB, this is a very interesting essay on the general area that appears in the current issue of Scientific American:
Demon-Haunted Brain: If the brain mediates all experience, then paranormal phenomena are nothing more than neuronal events.

Even if all we experience in our earthly lives is mediated in some level through the brain, that does not obviate the supernatural (ghost in the machine). That would be like saying that your face doesn't really exist, as far as my TV is concerned, because when it shows your image from a video camera, it is simply electronics and photons.
