Scientific Research into Near Death Experiences and Psi Phenomena by DOPS
DOPS, the Division of Perceptual Science, is a department within the University of Vriginia in the States that is dedicated to researching non-material phenomena such as altered states of consciousness, including out of body experiencies, psi, near death experiences and mediumship.
They've published a large body of research papers on the subject of near death experiences, including what happens physiologically to patients as they experience them, how the experiences can't be explained merely by abberant neural processing as brain function fails, the different experiences that people have (which are both good and bad), and the lasting effects that near death experiences have psychologically in the vast majority of people.
This is the description of their research from their home page:
"Founded in 1967 by Dr. Ian Stevenson, the Division of Perceptual Studies (DOPS) is the oldest and most productive university-based research group in the world devoted exclusively to the investigation of phenomena that challenge current physicalist brain/mind orthodoxy – including investigation of phenomena directly suggestive of post-mortem survival of consciousness.
Through its research, DOPS strives to challenge this entrenched mainstream view by rigorously evaluating empirical evidence suggesting that consciousness survives death and that mind and brain are distinct and separable.
As we expand our leading edge research, we believe mainstream academia will become more accepting of survival psi and that science will enlarge to take on new challenges in studying the nature on consciousness and its interaction with the physical world.
Simply put, our goal is to expand the current paradigm, because we believe that recognition of consciousness as something greater than a physically produced phenomenon is both more optimistic and more accurate than the prevailing materialist worldview."
