Near-Death Experiences: 30 Years of Research
DURHAM, N.C.—Grandma was just resuscitated. She wakes
up and tells you a bizarre story of coming out of her body and going to heaven.
Has she developed psychosis? Was her brain damaged from the lack of oxygen?
After over 30 years of research, scientists have concluded that this is not the case. Instead, they think that this phenomenon is something today’s science is yet to understand, and that it is an opportunity for the advancement of science.
The phenomenon was coined near-death experiences
(NDEs) in the 1975 book “Life After Life” by Raymond Moody, M.D. and Ph.D. in
philosophy and psychology. NDEs generally include cognitive, affective,
paranormal, and transcendental experiences.
Examples of NDEs include experiencing a change in
one’s perception and way of thinking, feeling peace or calmness, gaining
extrasensory perception (ESP), going through a review of one’s life and seeing
the effects of one’s actions on others, a feeling of leaving the body, seeing
deceased people and other beings such as angels, and feeling as if one has
entered another dimension.
NDEs are encountered by people of all backgrounds, and
most studies find the prevalence of NDEs to be 10–20 percent of people who have
come close to death.
Interest in studying NDEs was sparked after the
publication of Moody’s book. Then in 1981, the International Association for
Near-Death Studies (IANDS) was founded “to promote responsible,
multi-disciplinary exploration of near-death and similar experiences, their
effects on people’s lives, and their implications for beliefs about life,
death, and human purpose,” according to the IANDS website.
On Sept. 2–4, IANDS organized a conference in Durham,
N.C., for NDE researchers to present their findings.
Improved Mental Functions With an Impaired Brain
Bruce Greyson, M.D. and director of the Division of
Perceptual Studies at the University of Virginia, said NDEs are reliable
because the accounts by near-death experiencers (NDErs) of these events remain
unchanged over time. He compared a group of NDErs’ accounts about their NDEs
made 20 years apart and found that they remained closely identical over time.
Greyson believes that NDEs are an indication that the
mind is independent of the brain because impaired brain functions would be
expected during the clinical situation that the NDErs underwent, but his
research found no corresponding impairment of mental functions in NDErs.
“In most cases, people’s mental functioning is better
in the NDE than [it] is during our normal waking life,” Greyson said during an
interview with The Epoch Times.
“Their thinking is faster, is clearer, is more
logical, they have more control over their chain of thought, their senses are
more acute, their memories are more vivid.
“If you ask somebody about their near-death experience
that happened 15 years ago, they tell it as if it happened yesterday. If you
ask them [about] other experiences from their life at the same time, they are
very fuzzy memories, if they have any at all.
“[…] When you think that these experiences, which are
characterized by enhanced thought processes [that] takes place when the brain
is not functioning well or sometimes not functioning at all since it is in
cardiac arrest or deep anesthesia—times when brain science would tell us that
you shouldn’t be able to think or perceive or form memories—it becomes quite
clear that we can’t explain this thing on the basis of brain physiology.”
Eben Alexander, M.D., a neurosurgeon who also spoke at
the conference, had an NDE that’s a case in point. He contracted acute
bacterial meningitis, which damages the neocortex, in 2008 and went into a
coma, spending six days on a ventilator.
The glucose level of his cerebrospinal fluid was 1
mg/dl (milligram per one-tenth of a liter), while normal levels are between 60
and 80 mg/dl. When the level drops to 20 mg/dl, the meningitis infection is
considered severe. For days after the coma, Alexander struggled to speak and
recall memories before the coma. No one with this kind of severe brain damage
is expected to fully recover.
However, during his NDE, Alexander had such vivid
experiences involving multiple senses, such as vision, hearing, and smell, that
he said he couldn’t describe how amazing it was.
“My brain right now—I think it recovered pretty
well—could not do anything close to what my brain was doing,” Alexander said.
“How does a dying brain end up getting far, far more powerful and able to
handle these tremendous loads of information instantaneously and put it
altogether?”
