Near-death experience

Near-death experience, also known as NDE, is the common name for feelings, impressions and out-of-body experiences reported by people who have been resuscitated after a cardiac arrest.

Such reports date back to the time of Plato who wrote about the Myth of Er.ResearchersRaymond Moody, Elisabeth Kübler-Ross, Bruce Greyson, Kenneth Ring, andMichael Sabom have all researched and wrote about this subject. Greyson, Ring and Saborn helped start the field of Near-Death studies In the strictest sense an NDE occurs when someone is near death or has died. Dr. Raymond Moody writes: “By the classical definition, death is the state from which you don't return. It is defined as irreversible. Hence, since all of the NDEers returned, they were never really dead. Whjat happened was that various criteria for death were fufilled, p. 64 The Light Beyond. Both adults and children report similar NDE experiences. Similar experiences have been reported by others, who had not died, but NDE researchers do not consider them true NDEs. These experiences may occur when someone is participating in meditation, under emotional duress or at the bedside of a dying loved one. NDE researchers are studying this phenomena as part of their NDE research.

Scales

There two primary scales used to score NDE experiences. In 1980, psychologist Kenneth Ring developed the 10 point interview scale to analyze the NDE. Using this scale, Ring interviewed 102 people who had come close to death. The interview using the scale determined that 48 percent of Ring's group had experienced an NDE. Using this information he developed the Weighted Core Experience Index, p. 16 What Happens When We Die. Ring's Weight Core Experience Index asked about whether the NDE was peaceful; had an Out-of-Body experience (OBE); tunnel or dark area; saw a light; entered the light.

The Greyson Scale, developed by psychiatrist Dr. Bruce Greayson, was created after he interviewed 74 people who reported experiencing an NDE. He used the 16 most frequently reported features to develop his questionaire. Greyson's scale ask questions such as was there an experience of altered time; accelerated thought process; life review; a sense of sudden understanding; feelings of peace; feelings of joy; feeling of cosmic oneness; seeing or feeling the surrounding of light; reporting vivid sensations; extrasensory perception (ESP); experiencing visions; a feeling of being outside of the body (OBE); a sense being in an otherworldly environment; a sense of a mystical entity; a sense of deceased or religious figures; a sense of a border or point of no return. Each question is rated 0, 1 or 2. The potential maximum score was 32 and a score of 7 was needed to qualify for having an NDE experience, p. 17 What Happens When We Die.

There are variances between adults and children in what they may experience and describe concerning the NDE event. Cultural variations concerning NDE experience have also been reported.

Incidence

In a 1982 United States Gallup poll, the survey concluded approximately 8 million people had reported a near-death experience.Moody states the same statistics based on the Gallup poll information. The Gallup poll garnered the following statistics from the people reporting an NDE: OBE 26 percent; accurate visual perception 23 percent; audible sounds or voices 17 percent; feelings of peace or painlessness 32 percent; light phenomena 14 percent; life review 32 percent; being in another world 32 percent; encountering other beings 23 percent; tunnel experience 9 percent; precognition 6 percent, p. 5 The Light and Beyond.

Physician Sam Parnia states the actual frequency for an NDE in his study was around 6 percent (4 out of 63) for cardiac-arrest survivors. In his book What Happens When We Die Parnia states the oxygen levels were higher in the NDE patients than in the study control group. This study included four patients so it was not possible to determined if this was a legitimate or real finding, p. 86 What Happens When We Die.

Adults

Dr. Raymond Moody reported in his 1975 research a series of features found in his NDE research. Some of these features included a feeling of peace and quiet, hearing a buzzing or wind like sound; the sensation of leaving one's body; having a life review; reaching a border where if crossed there would be no return and finally the returning to the physical body. This information was collected from western society adults. In his book The Light Beyond, Moody further clarifies the NDE experience reported by people who have undergone this experience. His subjects have reported the following:

Peace

He writes “when the ribbons are cut there is a very real sense of peace and painlessness”. Cardiac patients, according to Moody, report the intense pain of a heart attack turns into pleasure. Moody states some researchers believe this effect could be caused by a self-made chemical to stop the pain. Moody states there have been no experiments to prove this is the case.

Out-of-Body Experience or the OBE

Moody reports his study subjects described seeing their body below while retaining a “body” of some sort they can not describe. The study subjects state their OBE body has a shape that may look like an energy field or filled with many colors. One person described their hands as being composed of light with “tiny structures in them.”

Tunnel

At this point, the dying person will realize this experience may have something to do with death writes Moody. A tunnel or portal will then be seen as the person is moved into darkness while moving towards a brilliant light. Moody also reports some people have witnessed a staircase going upward. Others have reported seeing ornately decorated doors instead of a tunnel. “The descriptions are many, but the sense of what is happening remains the same: the person is going through a passageway toward an intense light,” writes Moody.

Other witnesses have reported floating and a rapid rise into heaven. During this experience, the witness reports seeing the universe from the perspective reported by astronauts. Moody writes psychotherapist C.G. Jung described this experience in 1944 when he had a heart attack.

People of Light

The people or beings of light glow with intense luminescence that fills the person with love. The light is described as being much brighter than anything found on earth while not hurting the eyes. The person under-going this experience will usually see friends and relatives who have died. Joining this experience is the ability to see beautiful pastoral scenes. One female witness reported seeing plants filled with their own inner light. Other NDE subjects have reported seeing beautiful cities of light. Communication during this portion of the experience is nonverbal or telepathic.

Being of Light

The NDE witness will report seeing a holy supreme being of light. When meeting this holy being the person wants to remain but is told by the being of light to return to their earthly body.

Life Review

A panoramic review of every single thing the person has done in their lives takes place. “The closest description I've heard of it is that the whole person's life is there at once,” writes Moody. The being of light helps the person through the life review process. Moody states the NDE experiencer comes away from the experience realizing the most important things in life are love followed by knowledge. Some people also report a life review that includes foretelling of their future. One person reported knowing when and who he would marry. He also knew how many children he would have and where they would live, p. 23 The Light Beyond.

Return

NDE experiencers want to remain in the heavenly place and often experience short-term anger when they are brought back from death states Moody. Later the NDE patient is happy they survived and they are happy to have been given a chance to live Moody further writes.

Most often the NDE experiencer wants to return to life as they do not want to leave their children behind or they do not want their families to grieve. One woman reported to Moody she argued with the being of light to return to life. “But I am young, I haven't danced enough yet. At that point the being of light have out a hearty laugh and allowed her to live,” wrote Moody in his book The Light Beyond New Explorations.

Moody also states not everyone who under-goes an NDE experience will have “all the symptoms”. “It is the presence of one or more of these traits that define the NDE,” p. 6. He further states that after interviewing more than a thousand people, some have had full blown NDE experiences where all nine NDE traits.

In the book The Handbook of Near-Death Experiences, Bruce Greyson and Ian Stevenson in their 1980 research conducted a study of a sample of 78 NDE experiencers. In this study Greyson and Stevenson identified some of the features in an NDE. They included having an OBE, passing through a tunnel or similar structure, entering an unearthly realm, encountering beings, reaching a border or point of no return, hearing music or noises, having a sensation of warmth or analgesia, feeling a distortion of time, having extrasensory perception (ESP), and panoramic memory.

Most NDE experiencers felt the experiences was neutral or mildly negative followed by mildly positive. None reported the experience as being “very negative”.

Non-Western Near-Death experiences

In the book The Handbook of Near-Death Experiences, the authors state a total of 16 refereed journal articles described approximately 275 to 350 non-Western NDEs have been gathered since 2005. The experiences are gathered from Asia, Pacific area and hunter-gatherer cultures, p. 137.

Based on the historical work of Carl Becker and the empirical work by Fen Zhi-ying and Liu Jian-xun the following information was collected. Becker interviewed three Chinese Buddhist monks who were seriously ill and either had a NDE or or deathbed vision. No tunnel of light was reported by the monks although one did report “going through a void”. None reported an OBE or life review. All three monks did report visiting the “pure land.”

Medical doctors Zhi-ying and Jian-xun interviewed 81 survivors of the Tangshan earthquake. They found 32 NDE experiencers who reported most of the similar experiences found in Western NDE studies. The Chinese earthquake survivors reported OBEs, the tunnel experience, peace, life reviews, seeing deceased beings and seeing an unearthly realm of existence.

India

K. Osis and E. Haraldson interviewed 704 Indian medical personnel in 1977. The interviews dealt with their experiences with the dying. The interviews showed that 64 participants reported an NDE experience while the rest reported near-death visions. Satwant Pasrich and (first name unknown) Stephenson in 1986 reported 16 cases of NDE in India. Of the 16 reports, 10 of the reporting witnesses were directly interviewed. By 1993, a total of 45 cases were reviewed. The researchers found no evidence of tunnel of light and one person reported an OBE, p. 140

Thailand

Researcher Todd Murphy in 2001 collected 10 published NDE accounts. There was one report of an OBE but Murphy believed the Yamtoots, guides of the underworld, served the this function. No tunnel or tunnel-like experiences were reported by Murphy other than the one case reported. He wrote “tunnels are rare, if not absent, in Thai NDEs.” p. 141 The Handbook of Near-Death Experiences.

The Pacific Region

Researcher Kellehear found one case of a Hawaiian womam who died, was placed alongside the road for her funeral rites, and later revived. The woman reported walking out of her house and to her village. She then walked onto another village where she saw numerous people and then realized these people had died. She then felt the need to walk towards Pele's Pit known as the “jumping off of souls of the dead” p. 143 The Handbook of Near-Death Experiences. As she reached this point, she was told it was not her time to die and crowds of people drove her back to life. This tale was reported in 1907 in Thomas Thrum's Hawaiian Folk Tales, according to Kellehear. No reports of a tunnel or life review was reported in this incident p. 143 The Handbook of Near-Death Experiences.

New Zealand

Researcher Micahel King reported in 1985 the report of a Maori woman who died and reported hovering over her body. She later ascended to a ledge and looked at the entrance of the underworld. She performed a dance in preparation of entering the underworld. As she prepared to enter, a voice told her it was not her time and she returned to her body, p. 145 The Handbook of Near-Death Experiences. She did report an OBE but not the tunnel, although the author's in The Handbook of Near-Death Experiences speculate if she had gone through the entrance to the underworld it would have constituted a tunnel experience, p. 145 The Handbook of Near-Death Experiences.

Children

Pediatrician David Morse became interested in NDEs after one of his patients told about her NDE. She was resuscitated after nearly drowning. Katie spent three days near the brink of death and was kept in a deep coma. On the third day she awoke as if from a deep sleep and by the next day was visiting with family. She showed no signs of brain damage. Morse interviewed the girl about what she remembered from the experience and was told about her visit to heaven. Morse reports a person actually needs to be near death to have a near-death experience. He also reports the ara in the brain near the right temporal lobe is genetically coded for near-death experiences, forward to the book Closer to the Light.

Morse created the Seattle Study to determine if someone needed to be near death in order to have a near-death experience. The control group of 121 seriously ill children had a less than five percent chance of dying but were ill. The study group of 12children who faced death. Morse interviewed children based on the psychological experience of being in an intensive care unit with no mention of NDEs. Interviews lasted approximately two hours and asked questions such as what the patient remembered while being sick, dreams and hospital experiences, p. 20 Closer to the Light. 118 of the children who were seriously ill, but not close to death, did not remember their hospital experience, p. 21 Closer to the Light.

The experimental group, the cardiac survivors or ones who awoke from deep comas, most of the children did report at least one feature of the NDE experience. Morse states the child would often start telling of their experience with a puzzled look. He gave the example of “Well, I kind of remember a really funny thing that I can't exactly telly. I was looking at myself and going somewhere, but I didn't exactly know where,” p. 23 Closer to the Light. Morse said the children would go onto tell about their NDE experience. Some of the children were not affected by the experience while others were profoundly affected.

Children's reports

Here is a small selection of reports collected by Morse in his book Closer to the Light.

Patient Two, known as Chris, who related this story after under-going cardiac surgery at the age of 10. “I have a wonderful secret to tell you Mother. I've been climbing the staircase to heaven. It was such a good and peaceful feeling. I felt wonderful. I was on a staircase, and it was dark, and I started climbing upward. I got about halfway up the staircase and decided not to go any higher. I wanted to go on up, but I knew I wouldn't come back if I went too high. That would hurt my mom and dad; since my little brother had already died, they wouldn't have anyone to take care of,” p. 27 Closer to the Light. He returned to his body by turning and going down the staircase.

Patient Five, known as June, drowned when her hair was caught in a pool drain. June went onto to relate the following story:

“All I remember was my hair getting stuck in the drain and then blacking out. The next thing I knew, I floated out of my body. I could see myself under the water but I wasn't afraid. All of a sudden I started goint up a tunnel and before I could think about it, I found myself in heaven. I know it was heaven because everything was bright and everyone was cheerful. 'A nice young man asked me if I wanted to stay there. I thought about staying; I really did. But I said 'I want to be with my family'. Then I got to come back,” p. 32 Closer to the Light.

In his book The Light Beyond Moody gives several examples of children who experienced NDEs. While a resident at a Georgia hospital Moody discovered a nine-year-old boy, who he called Sam, that told him about how he died the previous year from a cardiac arrest. Moody writes that Sam told him about he floated out of his body and watched his doctor perform CPR to restart his heart. Sam then reported that he began to move rapidly away from the earth and towards a dark tunnel. He passed through the tunnel where he was met by a group of “angels”. He told Dr. Moody the angels did not have wings but described them as glowing. He described the place as filled with light and saw beautiful pastoral scenes encircled by a fence. The angels said if he went past the fence he would not be able to return to life. He then encountered a being of light who (Sam told Moody this was God) who told him he had to return to his body, p. 46

The NDE experience is similar between adults and children. Children though are typically accompanied by someone when they enter the light while adults usually do not report this experience, p. 105 The Handbook of Near-Death Experiences. Children may also be accompanied by a deceased family pet during an NDE, p. 98 The Handbook of Near-Death Experiences.

Of note preverbal and nonverbal children may indicate they witnessed the tunnel during the NDE, p. 98 The Handbook of Near-Death Experiences. This information was discovered after observing how some children became fearful of tunnel-like objects. One child who experienced this fear of tunnels later asked if her grandmother would have to go through the tunnel found at a grocery store so she could see God.

Adults, who report childhood NDE experiences later in life, are reliable and not distorted or changed to fit cultural or social expectations, p. 105 The Handbook of Near-Death Experiences. Moody states the near-death experiences of children give better evidence for an afterlife as they have not been influenced by cultural material, p. 60.

Colton Burpo

Colton Burpo, 4, nearly died from a ruptured appendix, but lived to tell about his trip to heaven. The book Heaven Is Real tells of Burpo's near-death experience and how he sat in the lap of Jesus. He also saw God and the mother of Jesus, Mary, during his NDE. Burpo gives detailed accounts from the viewpoint of a young child and often describes heaven as a place of rainbows, animals and people who wear wings. Colton reports seeing dead relatives including a beloved family member named Pop, who he later identified in a photo; and told about seeing a sister (she died in utero) who died before he was born. Colton did not know of his mother's miscarriage until after telling about seeing his sister. His father, Todd Burpo who is a pastor, and provides biblical documentation to back up what his son reports.

Veridical NDE

The apparently nonphysical veridical NDE perception (AVP) is when the NDE experiencer either through the current condition of the NVP or position of their body during their experience could not have been caused by normal sensory processes. The reported experience is backed up or corroborated as having a consensus to reality, p. 186 The Handbook of Near-Death Experiences.

AVP experiencers are further defined as undergoing reversible death and were revived. “...from a purely scientific perspective, the nature of person's consciousness during reversible death may or may not indicate the nature of one's concerning during irreversible death. The consciousness associated with a body that has not yet lost the potential to live may or may not be the same as the consciousness associated with a body that has lost that potential,” p. 187 The Handbook of Near-Death Experiences.

One of the best documented cases of AVP concerns Pam Reynolds who under went surgery for a brain aneurysm. Neurosurgeon Robert Spetzler performed a “hypothermic cardiac arrest” during surgery in order to repair the aneurysm. Below is a paraphrased summation of the report filed by Spetzler. This information was found in The Handbook of Near-Death Experiences and was paraphrased from To Light and Death written by NDE researcher Michael Sabom.

At 7:15 a.m. Reynolds is brought into the operating room in a conscious state, she is then given intravenous petnathol where upon she reported a loss of time. Her eyes were taped shut and general anesthesia was administered. Monitoring devices were then instrumented to her including EEG electrodes to her head. Small speakers were molded to and inserted in both of her ears to emit a 95 decibel clicking sound that would register on a monitor of her brain stem. By 8:40 a.m. an incision was made into her scalp and a section of her skull was removed. It was determined the hypothermic cardiac procedure would be performed due to the size of the aneurysm. By 10:50 a.m. The blood cooling and cardiopulmonary bypass was underway. At 11 a.m. Reynold's core body temperature was 73 degrees F. At 11:25 a.m. Her core body temperature was 60 degrees and “the clicks from the ear speakers no longer elicited a response,” p. 192 The Handbook of Near-Death Experiences. The aneurysm was repaired and the process of restoring normal body functions began. At 12 noon the heart monitor showed ventricular defibirilation and two defibrilation shocks were administered. Her heart beat normally. By 12:32 p.m. Her body temperature registered 89.6 degrees and the monitoring equipment was removed. She was taken to the recovery room in stable condition at 2:10 p.m.

Reynolds reported hearing the cranial saw after the pentathol was administered. As a musician, she was able to determine that she saw a natural D tone emitted and that sound pulled her out through the top of her head. Reynolds claimed a greater sense of awareness and enhanced vision. She also observed surgical procedures such as the tools used to operate and observed the way her head was shaved. She also encountered deceased loved ones including an uncle “giving her a push back” to help her enter her body. Reynolds said her reentry into her body felt like jumping into a pool of ice water.

Hellish NDEs

Key reported components of the hell-like NDE include seeing lifeless or threatening apparitions; barren or ugly landscapes; hearing threats, screams or perceiving silence; feeling a sense of danger or the possibility of violence including torture; a feeling of cold or temperature extremes and a sense of hell, p. 69 The Handbook of Near-Death Rxperiences.

In a study conducted by Hubert Knoblauch, Ina Schmied and Bernt Schnetter they studied 82 German participants. Of the 82 study contributors 4 percent reported NDEs. Of those NDEs 60 percent of the West German correspondents reported positive NDEs (or emotions) while 29% reported negative (or emotions) in the study. Of interest was the difference between the West and East German study participants as the East German participants reported 40 percent positive and 60 percent negative in this study sample. “The authors concluded that not only the interpretation but 'also the very content of what is experienced...is culturally constructed,” p. 69 The Handbook of Near-Death Experiences.

Montana State University Health Science Professor William Serdahely reported in his study of 12 NDE experiencers 33 percent considered the experience scary or frightening, p. 69 The Handbook of Near-Death Experiences. The scantiness of statistics concerning hellish NDEs may be based upon the lack of wanting to disclose this experience states medical social worker Kimberly Clark Sharp. She says people will call and start to discuss their negative experience and then change their mind, p. 70 The Handbook of Near-Death Experiences.

Blind can see during an NDE

Morse writes about Vicki Umipeg who developed blindness as a premature baby. Umipeg had her first NDE and reported seeing Jesus who had woolly hair. This experience happened during an appendectomy at the age of 12. She saw Jesus and had a brief life review. She was told to be kind and show others how to be kind. As an adult she had a second NDE after being in an auto accident. During this experience she arose from her body, traveled through the tunnel, saw deceased relatives and friends and saw Jesus. She was instructed by Jesus to not touch anyone nor to cross through the gate as it wasn't her time. She returned to her body through a tunnel with holes and saw people traveling along similar paths alongside her. She felt like she was being propelled along. During this experience she heard fanlike sounds, chimes and smelled the scent of jasmine. During this experience she received knowledge of all sorts. "...there was a brief time when knowledge came to her on most any topic; mathematics, science, astronomy, building, sewing....she would think it and the knowledge would come. She didn't bring the knowledge back with her, but she remembers having it. Jesus told her she must go back to have her children, and that someday she'd have all that knowledge again. She was told she had to go back to learn and teach about loving and forgiving, then she had a very intense life review and was returned."

Morse writes Umipeg has never developed any light perception although she had some 'facial vision' but that has lessened after her auto accident. 'To 'see', has memories of things by touch, but in NDE's objects were "percieved from a distance" and felt "very eerie". She didn't see colors and doesn't know what 'colors' are, but saw different brilliances of light, and having never seen light, it was "almost appalling (to see light during her NDE.)'

Transformation

Moody writes that all of the clinicians and scholars he has talked to, and who have interviewed NDE experiencers, said the experiencers were better people because of the NDE, p. 27 The Light Beyond. He cites research done by Charles Flynn who found that NDE experiencers developed a greater concern for others after their experience. They also developed an increased belief in the afterlife and a lessened fear of death, p. 28 The Light Beyond. “Loss of the fear of death was reported with the greatest frequency. NDErs have tended to attribute this loss to a new or strengthened belief in survival of bodily death,” p. 45 The Near-Death Handbook. While they retained their fear of dying their experience had lessened the fear of death itself. They also developed a greater sense of spirituality which was enhanced or new to the experiencer. They may also report a greater sense of purpose in their life and many reported they were sent back to complete their work. Sometimes their mission was not clear, but the NDE experiencer felt there was need for their return and a mission to accomplish. Many of the NDE experiencers also reported a sense of being detached from their body or they felt imprisoned by their body, p. 46 The Handbook Of Near-Death Experiences. They also reported greater compassion and a desire to serve after their experience.

Patient One in Morse's book Closer to the Light states “I know one thing. I am not afraid to die. My near-death experience has made me more aware of life. It has kept me from being interested in drugs or driving around in cars and getting high like my friends do, “ p. 166.

Paranormal experiences

Interestingly NDE experiencers developed an increased frequency for paranormal experiences.

Theories of what may cause a Near-Death Experience

The Birth Tunnel experience

Astronomer Carl Sagan proposed the NDE is a leftover birth memory. Sagan writes in his book Broca's Brain: Reflections on the Romance of Science every human being has the shared experience of birth to back up his theory.

Carbon dioxide overload

Some researchers think a carbon dioxide overload in the brain may cause the NDE.

Endorphin model

Endorphins are produced in the brain to help alleviate pain. The “runners high” is a good example of this phenomena. Dr. Daniel Carr proposes the brain produces endorphins to help ease the pain of dying. “There is no evidence in the medical literature that the stresses of dying actually produce significantly greater amounts of endorphins in the brain,” writes Morse, p. 191 Closer to the Light.

Hypoxia

Morse writes there was no evidence that patients who experienced NDEs were any more deprived of oxygen than the control group that did not have NDEs.

Near-Death-Like experiences that are not

• LSD – People who use this drug may feel like they've left their bodies. They also know they are not experiencing reality.
• Morphine and Heroin – People using these drugs usually do not perceive this experience as real. They also may experience nausea and vomiting. Nor does it usually involve seeing the tunnel of light, seeing the light, or having concrete visions of heaven.
• Recreational drugs such as marijuana, cocaine, PCP, apmphetamines and barbituates tend to cause paranoia, speech disturbances, loss of control of thought processes, poor memory, depression and fear. No NDE-like experiences are reported when recreational drugs are used.
• Anesthetic Agents – Halothane, surital, nitrous oxide, narcotics, and Membutal do not cause hallucinations. The patient may hear conversations while under the influence of one of these agents and become confused.
• Ketamine – Another anesthetic agent no longer used. When use patients reported frightening OBEs and they may have seen mirror images of themselves (autoscopic) when under the influence of this agent. Patients also know they are under the influence of drugs during this experience.
• Transient Depersonalization – The person becomes emotionally detached from their bodies during a near-fatal experience. Morse writes he's found no evidence of this in the children he interviewed after their NDE experience.

The above information was paraphrased from the book Closer to the Light by Morse.

Reported mechanisms

Not everyone agrees about what causes the reported NDE. Some believe the event is a peek into the the afterlife while others discount the experience as being caused by some form of artificial means discounting the afterlife aspect.

University of Montreal neuroscientist Mario Beauregard examined the brains of 15 people who reported near-death experiences. The participants relived their experiences while Beauregard completed the exam using electrodes and an isolation chamber. Beauregard noted there was a shift in their brain and the shift would allow these people to stay in touch with the spiritual world.

Auckland pyschiatrist Karl Jansen attributes NDEs to “underlying mechanisms in more mysterious realms that cannot currently be described." He does attribute NDEs partly to neurochemistry andpsychology.

Neurologist Kevin Nelson believes NDEs are not imagined but lie within the brain itself. He attributes NDEs to Rapid Eye Movement (REM) state. Nelson also believes the NDE bright light is caused by visual stimulation in the brain due to the REM. The tunnel is also caused by a decrease of blood flow to theeye.

Mark Mahowald, director of the Minnesota Regional Sleep Disorders Center, believes there is nothing mysterious about NDEs. He attributes NDEs to oxygen starvation in the brain.

Laboratory-induced NDE

Recently, it has been established that the spectrum of effects attributed to near-death experiences can be fully reproduced, at will, by area-specific stimulation of the brain by magnetic resonance imaging techniques in combination with sensory deprivation.

The seat of the soul

There are many theories on what causes an NDE, but none have been proven. Morse writes in his book Closer to the Light the right temporal lobe when electrically stimulated has caused patients to report 'seeing God'. He first came up with this theory after discussing NDEs with Art Ward who was the chairman of neurosurgery at the University of Washington. During their conversation, Ward reported many of his own patients had reported similar experiences. He recalled one patient who experienced every trait of the NDE experience after an area of his brain was examined with an electric probe. Wilder Penfeld was conducting the examination reported Ward. After this discussion between Morse and Ward further research was done concerning Penfeld's work. The area being mapped was called the Sylvian fissure located in the area of the right temporal lobe, p. 104-105 Closer to the Light. Researchers in Chile confirmed that near-death experiences were caused by neuron activity within the Sylvian fissure.

“Learning that other scientists had reached the same conclusion independently told us that we had at least discovered the circuit boards of mysticism. In our hearts, some of use believed strongly that we had discovered the seat of the soul,” p. 110 Closer to the Light.

Near-death experience, also known as NDE, is the common name for feelings, impressions and out-of-body experiences reported by people who have been resuscitated after a cardiac arrest.

Such reports date back to the time of Plato who wrote about the Myth of Er.ResearchersRaymond Moody, Elisabeth Kübler-Ross, Bruce Greyson, Kenneth Ring, andMichael Sabom have all researched and wrote about this subject. Greyson, Ring and Saborn helped start the field of Near-Death studies In the strictest sense an NDE occurs when someone is near death or has died. Both adults and children report similar NDE experiences. Similar experiences have been reported by others, who had not died, but NDE researchers do not consider them true NDEs. These experiences may occur when someone is participating in meditation, under emotional duress or at the bedside of a dying loved one. NDE researchers are studying this phenomena as part of their NDE research.

When do NDEs occur?

Retired Dutch cardiologist Pim van Lommel says when the body is in this state it is like a computer that is unplugged from its power source with its circuits detached. “It couldn't hallucinate. It couldn't do anything at all,” says Lommel in an interview with Time magazine. Many NDE researchers believe this is the time period when NDEs are likely to occur. “"Many near-death experiencers describe heightened perceptions and clear thought processes, and form memories, at a time when the brain is incapable of coordinated activity," says Greyson, director of the University of Virginia's Division of Perceptual Studies. "Our current neurophysiological models can explain NDEs only if one ignores much of the empirical data,” he said during his interview with Time magazine.

Commonly reported experiences

In general the NDE experience goes through the following steps:

• Hearing the News
• Feeling of peace and quiet
• The noise
• The dark tunnel
• Out-of-body experience
• Meetings others
• The Being of Light
• The Review
• The border or limit

Another description of the NDE event is given in the Near-Death Experiences: Is this what happens when we die. In this report people who experienced an NDE detailed most of the experiences reported by Ring.

Ring estimates 23 million Americans have had NDEs, and that no matter the cause of death or religious persuasion; people have neared biological death, or died, have reported NDEs.

Negative experiences

Not everyone reports NDEs as being pleasant. Greyson states some people reporthellish experiences. A woodcutter, who attempted suicide by hanging, described hearing but not seeing demons. Some how he was able to alert his wife during his NDE experience who ran to her husband and cut him down. This all happened and was reported by him during his NDE experience. He was later revived by emergency personnel and lived to tell about his NDE. Some researchers believe his cry for help was heard through telepathy. Other experiences commonly reported moving towards the tunnel of light and other commonly reported features except the person felt out of control during the experience. Another experience reported includes being an absolute void. Some have also reported they felt like the world never existed. Finally, a rare form of NDE is when the person reports a negative life review and negatively judged. Approximately 1 to 15 percent of people report negative NDEs. A negative NDE is not based on the cause of death or religious background. Further research is planned.

NDE effects

Research has shown the NDE experience has long-term effects. People who have died and returned to report the NDE often change lifestyles. Women may become more outspoken while men may become emotionally in tune. Other effects may include learning to love universally, looking at time as flowing or “to flow with events.” Some people have reported developing psychic abilities such as extrasensory perception (ESP) after their NDE experience. Children may develop a lessening of the bonds between parent and child; increased sensitivity to others; increased service to others, increased interest in spirituality; communication with spirits (often called angels or guides by the child); sensitivity to bright lights, loud noises and medications; a strong desire to volunteer for charitable causes. Children who reported an NDE may also develop altered biological patterns such as sleep or attentiveness. Some may report synesthesia, increased intelligence, and an increased ability to grasp abstract concepts.

Reported mechanisms

Not everyone agrees about what causes the reported NDE. Some believe the event is a peek into the the afterlife while others discount the experience as being caused by some form of artificial means discounting the afterlife aspect.

University of Montreal neuroscientist Mario Beauregard examined the brains of 15 people who reported near-death experiences. The participants relived their experiences while Beauregard completed the exam using electrodes and an isolation chamber. Beauregard noted there was a shift in their brain and the shift would allow these people to stay in touch with the spiritual world.

Auckland pyschiatrist Karl Jansen attributes NDEs to “underlying mechanisms in more mysterious realms that cannot currently be described." He does attribute NDEs partly to neurochemistry andpsychology.

Neurologist Kevin Nelson believes NDEs are not imagined but lie within the brain itself. He attributes NDEs to Rapid Eye Movement (REM) state. Nelson also believes the NDE bright light is caused by visual stimulation in the brain due to the REM. The tunnel is also caused by a decrease of blood flow to theeye.

Mark Mahowald, director of the Minnesota Regional Sleep Disorders Center, believes there is nothing mysterious about NDEs. He attributes NDEs to oxygen starvation in the brain.

Laboratory-induced NDE

Recently, it has been established that the spectrum of effects attributed to near-death experiences can be fully reproduced, at will, by area-specific stimulation of the brain by magnetic resonance imaging techniques in combination with sensory deprivation.

Near-death experience, also known as NDE, is the common name for feelings, impressions and out-of-body experiences reported by people who have been resuscitated after a cardiac arrest.

Such reports date back to the time of Plato who wrote about the Myth of Er.ResearchersRaymond Moody, Elisabeth Kübler-Ross, Bruce Greyson, Kenneth Ring, andMichael Sabom have all researched and wrote about this subject. Greyson, Ring and Saborn helped start the field of Near-Death studies In the strictest sense an NDE occurs when someone is near death or has died. Both adults and children report similar NDE experiences. Similar experiences have been reported by others, who had not died, but NDE researchers do not consider them true NDEs. These experiences may occur when someone is participating in meditation, under emotional duress or at the bedside of a dying loved one. NDE researchers are studying this phenomena as part of their NDE research.

When do NDEs occur?

Retired Dutch cardiologist Pim van Lommel says when the body is in this state it is like a computer that is unplugged from its power source with its circuits detached. “It couldn't hallucinate. It couldn't do anything at all,” says Lommel in an interview with Time magazine. Many NDE researchers believe this is the time period when NDEs are likely to occur. “"Many near-death experiencers describe heightened perceptions and clear thought processes, and form memories, at a time when the brain is incapable of coordinated activity," says Greyson, director of the University of Virginia's Division of Perceptual Studies. "Our current neurophysiological models can explain NDEs only if one ignores much of the empirical data,” he said during his interview with Time magazine.

Commonly reported experiences

In general the NDE experience goes through the following steps:

• Hearing the News
• Feeling of peace and quiet
• The noise
• The dark tunnel
• Out-of-body experience
• Meetings others
• The Being of Light
• The Review
• The border or limit

Another description of the NDE event is given in the Near-Death Experiences: Is this what happens when we die. In this report people who experienced an NDE detailed most of the experiences reported by Ring.

Ring estimates 23 million Americans have had NDEs, and that no matter the cause of death or religious persuasion; people have neared biological death, or died, have reported NDEs.

Negative experiences

Not everyone reports NDEs as being pleasant. Greyson states some people reporthellish experiences. A woodcutter, who attempted suicide by hanging, described hearing but not seeing demons. Some how he was able to alert his wife during his NDE experience who ran to her husband and cut him down. This all happened and was reported by him during his NDE experience. He was later revived by emergency personnel and lived to tell about his NDE. Some researchers believe his cry for help was heard through telepathy. Other experiences commonly reported moving towards the tunnel of light and other commonly reported features except the person felt out of control during the experience. Another experience reported includes being an absolute void. Some have also reported they felt like the world never existed.
