Penny Sartori and Bruce Greyson say much the same thing about the brain and consciousness. Sartori says the brain doesn't create consciousness; it mediates it.

Sartori and Greyson are leading researchers in near-death studies. Out-of-body experiences are common in NDEs, and the fact that a person could perceive his or her own body from a vantage point wholly outside the body, to my mind, lends credence to what you're saying.
