I am sure you are aware of Blanke's experiments, concerning epileptic patients and the angular gyrus. In order to simulate an OBE-feeling, that part of the brain had to be exposed to an electrical current.
And, Robert Monroe did some experiments with a Faraday Cage, but I did not read that book, so you would have to look into it.
