Pim van Lommel, MD, a cardiologist from Holland lectured that his frontier research on near-death experiences is based on a multi-site, longitudinal clinical trial. He found that many people who survive cardiac arrest described strikingly similar experiences to those of near-death reports.
Nonlocal Consciousness: An explanatory model for the Near-Death Experience
Pim van Lommel, M.D.
Since the publication of several prospective studies on near-death experiences (NDE) in survivors of cardiac arrest, with strikingly similar results and conclusions, the NDE can no longer be scientifically ignored. It is an authentic experience which cannot be simply reduced to imagination, fear of death, hallucination, psychosis, the use of drugs, or oxygen deficiency, and people appear to be permanently changed by an NDE during a cardiac arrest of only some minutes duration. The current materialistic view of the relationship between the brain and consciousness held by most physicians, philosophers and psychologists seems to be too restricted for a proper understanding of this phenomenon. One has to come to the inevitable conclusion that consciousness cannot be localised in a special time nor place (nonlocality), and there are good reasons to assume that our consciousness does not always coincide with the functioning of our brain. So research on NDE seems to be a source of new insights into the possibility of a continuity of our consciousness after physical death.
