Crossing the line of life and death

For a long time, the mainstream scientific community did not take the so-called “death experience” seriously, but thought that these “experiences” were merely illusions caused by factors such as anesthesia, hypoxia or belief. But there are always some scientists who don’t think so, because their research suggests that the actual situation may not be the case. A four-and-a-half-year new study involving 2,060 patients (supported by the University of Southampton, UK) – The results of the Blue Brain Project were released and noted that during the period after cardiac arrest, when “the brain and After the body is dead, “consciousness” may still exist. The leader of the study, Sam Pania, assistant professor of intensive care medicine and director of resuscitation research at the State University of New York, pointed out that although it is impossible to absolutely prove the “death experience” or “post-death consciousness” It is true (because the incidence of such phenomena is too low), but it is impossible to categorically reject these claims, but it is necessary to conduct more research in this field.

The real case of the sudden death experience

The Blue Brain Project is dedicated to building a human brain inside a supercomputer.

The study included a study called Resuscitation Awareness. The recovery here means that after the patient’s heart stops beating, the doctor takes steps to pull them back from the death line. It is this work that Pania has been working on. Of the 140 patients interviewed by scientists in the Resilience Awareness study, 9% reported a “death experience” that met the criteria set by American psychologist Bruce Gleason. But Pania believes that the actual proportion of patients with a “death experience” may be higher than this percentage because some experiences are not immediately recalled. Pagna said that 39% of the patients who had survived the cardiac arrest were able to be interviewed and described their awareness during the heartbeat, but interestingly, they all lacked any clarity on the events at the time. memory. This suggests that more people who have recovered from the death line may have experienced conscious activity at first, but lost these memories after the recovery. This is either due to brain damage or because of the effect of the anesthetic on memory.

Using a similar but larger approach to earlier research, the Pania team installed special shelves in hundreds of wards in 15 hospitals in the UK, the US and Australia. These wards may place patients with cardiac arrest. The special shelves are mounted on the upper part of the ward wall, and an image is placed on the shelf, and the image can only be seen above the shelf. In addition, the images on each shelf vary, and their themes include countries, religions, people, animals, and newspaper headlines. The reason why the shelf is set up is because many of the “sudden death experiencers” include “the process of recovering from the position of the heartbeat” at the top of the observation position.

The Paya team also trained nurses and doctors to visit patients who agreed to be interviewed. Of the 140 patients interviewed, two described the “death experience” content (including heard and seen) matched the medical report, although the two were not placed in a ward with a special shelf. One of them was unable to continue to be interviewed due to serious illness, but the other (57-year-old male) described the following “death experience” in detail:

“I clearly remember that there was a machine voice saying: ‘The electric shock patient, the electric shock patient. Then, in a corner of the ward, a woman nodded to me… The next second, I floated over myself, observing myself in the hospital bed, nurse And another bald man… I can’t see his face, but I can see his back. He is a strong guy… He washes his arm with blue liquid and he wears a blue hat. But I am from He can see that he has no hair.”

The Pania team said that the above description is in complete agreement with the actual situation of the patient during the approximately 3 minutes of cardiac arrest. But this 3 minutes sounds contradictory, because the brain usually stops working after 20 to 30 seconds of heartbeat, and unless the heart recovers, the brain can’t resume operation. In fact, during the heartbeat of the patient, the researchers performed some deliberate auditory stimuli on him and recorded the time course, which was heard and recalled by him, and the chronological order also matched. It seems that this cannot be completely explained by the illusion. More importantly, the patient’s memory of death should also occur after brain death (which is considered a reasonable criterion for determining death), and if so, does it indicate that consciousness is a short time after death Still exists? Or is it not reasonable that brain death is equivalent to true death?

An American intensive care unit nurse who is working on a near-death experience and published the book “The Sudden Experience of Intensive Care Units: Five-Year Clinical Study” said that the above description of the experience of sudden death did not surprise her. Of the 39 patients who recovered after 39 heartbeats she studied, 7 reported a memory after the ECG showed a flat line (ie, clinical death). She also said that this is really important because it does show us this: as we become more aware of our consciousness, our understanding of this aspect is changing. She also said: More and more scientists realize that consciousness may not be confined to the brain, and the traditional understanding of the phenomenon of consciousness is flawed; the scientific community has always believed that consciousness is a by-product of the brain, but a new guess is The brain may play the role of a filter, sometimes it will filter the consciousness, and sometimes the filter will fail, and people will experience an excited state of consciousness.

However, such new speculations are not actually accepted by the mainstream scientific community. Pania said that the above new research may stimulate new research and new controversy on the phenomenon of consciousness, but there is no doubt that the scientific community has not thoroughly understood the relationship between consciousness and the brain, which is still the largest science. One of the mysteries, so it is undoubtedly necessary to tirelessly explore this.

The new research report written by the Pania team states:

The content of the “death experience” seems to be much broader than the “death experience” that has been known so far; in some cases of heartbeat stop, the memory of visual consciousness matches the experience of the so-called “soul out”. This may be in line with the actual situation, but whether it can be called “soul out” is open to question; terms that are widely used but are not scientifically precise (such as “death experience” and “soul out”) may be insufficient. To describe the real death experience. Future research should focus on cardiac arrest (ie, clinical death). Although this phrase is synonymous with death in biology, it is not the same thing as death, because patients with heartbeats are likely to recover, and scientists should explore better ways to resuscitate them; Memories are worthy of serious investigations by the scientific community without prejudice.

Pania said that contrary to general knowledge, death does not occur at a specific moment, but rather a potentially reversible process that occurs after any disease or accident causes the heart, lungs and brain to stop working. If measures are taken to reverse this process, it is called “heartbeat (heartbeat) stop”, but if these measures are not successful, it is called “death.” In the new study, they did not stop at the scientific terminology that was not deterministic—the “death experience”, but rather focused on more objectively exploring what happens when people die.

A new exploration of the experience of sudden death
With the continuous development of cardiac resuscitation technology, reports on the experience of sudden death are also increasing. Many scientists believe that these experiences are merely hallucinations, and some supernatural phenomenon researchers call these evidences of life after death. The latest research suggests that the “conscious boundary” theory can be used to explain the vast majority of sudden death experiences.

The story of Gillian Mackenzie

Gillian Mackenzie’s sudden death experience occurred many years ago, long before the word “death experience” had not appeared. Today, Gillian’s scene of the dying of dystocia in the past is still vivid.

She felt like she was entering a dark tunnel. Except for some bright spots, it was dark. She vaguely remembered that she had bleeding during childbirth. She was worried about the unborn child, but the light in the dark made her feel at ease. “The light spot started like a small needle tip. I realized that I was attracted by the light spots and gradually approached it. The light spots became bigger and bigger, illuminating the walls of the tunnel, I entered the tunnel and saw That piece of light. I am not afraid, it is a very happy and wonderful feeling, a feeling of fascination. Suddenly I heard a male voice calling my name: ‘Gillian, the voice is very sweet. I thought, oh, I came to God, but I didn’t even believe in God before! He asked if I knew who he was, I said, yes, but I am afraid I can’t name you. He obviously has a good sense of humor. I listened to my words and giggled.”

Gillian said that she met the grandfather who died two years ago in the experience of dying. She told him that she had a boy. She felt herself floating above her body and watching the doctor rescue herself. She floated and followed her husband Hamishi downstairs to the hospital corridor, watching him call her mother. Gillian said, “I am not afraid at all, but I thought, how can I let Hamishi know that I am fine, I will return to my body?”

Gillian, who is now living in Sussex, England, said, “I told my grandfather that I have to leave because I have to go back to take care of my husband and children, and then I will go back.” In the days to come. Through the memory of the experience of dying, Gillian has a better understanding of life, she feels that she has become a different person from the past. She said, “You can make various reasonable explanations for the sudden death experience like me, but often miss the important point, that is, this experience has a profound impact on our lives, and this is the most Important, because it takes away the fear of death and makes life better. People can call such experiences hallucinations, but they are a reality for us, a real thing that has happened. ”

Various examples of sudden death experience

The scene described by Gillian is the experience of sudden death. The so-called sudden death experience refers to some personal experiences that people produce when they die, including the separation of consciousness from the body, the feeling of being suspended in the air, feeling extreme fear or tranquility, safety and warmth, seeing tunnels and light, and so on. These phenomena are usually caused when a person has been declared clinically dead or otherwise very close to death and is therefore referred to as a near-death experience. With the continuous development of cardiac resuscitation technology, more and more reports on the experience of sudden death. A sample survey of Americans from 1980 to 1981 showed that 15% had a near-death experience. According to a sample survey conducted in Germany in 2001, 4% experienced a near-death experience. A sample telephone survey in Australia in 2005 showed that 8.9% experienced a near-death experience. A Dutch cardiologist surveyed a group of patients who survived cardiac arrest in clinical practice and found that 62 of them (18%) had a sudden death experience.

There are different views and explanations on the experience of sudden death in biology, psychology and religion. Many scientists believe that this is just an illusion, and some supernatural phenomenon researchers say that this is evidence of life after death. The latter classifies the near-death experience as the experience of the body (or the soul). a form of.

The study found that there are many factors that can trigger a sudden death experience, such as dying sudden death, surgery, dreaming, psychedelic drugs, extreme stress, heart attack, hallucinations, rapid eye movement sleep, so-called alien abductions Wait. Here are some examples.

A dying state of death (John Star’s sudden death experience)

This state is most likely to trigger a near-death experience. Although there are established death standards, science cannot accurately define death. Sometimes the patient is judged to be clinically dead, but then miraculously “dead and resurrected.” Usually in this case a very unique sudden death experience will result.

When a man named John Star swims in Lake Michigan, he is in danger about 800 meters offshore: a wave of heads is coming and his lungs are filled with water. He didn’t know if he could swim back to the shore quickly if he couldn’t breathe. He felt like he was going to die, but he eventually survived miraculously. The following is a summary of his extraordinary self-declaration of sudden death experience –

I felt dizzy, and after a loud noise, I suddenly felt the peace around me. There was a light behind me, I stared at it, it gave me a very comfortable feeling, bathed in this light, like a dry sponge greedily sucking water, and it seems that I have been sealed in a vacuum tank for a long time. In the middle, now the jar is opened, the pressure is gone, and I can breathe again. I feel that energy is flowing into my body, and the whole person feels relaxed, excited and happy.

The ruler of time seems to be soft and flexible, so flexible as a rubber band, I can go back to any previous time period and clearly recall anything that happened. I went back and forth in the memories of my life. It seemed to stay for a few hours, and it seemed to be in a moment, and finally returned to the light.

I found that the original time can also be shrunk. The centuries of time condensed into minutes and seconds. Tens of thousands of years passed by. The entire process of civilization in which I was in the blink of an eye swept away from my eyes, and I was amazed. . I was dragged into the light, all the doubts in my life, all the guilt, all the happiness and all the fears disappeared at this moment, only this piece of light, and a wonderful feeling of happiness. Just like being in a troubled dream, someone walked into the room and turned on the light, letting me wake up from my dreams, and all the dreams disappeared. Just as I woke up in sleep and gradually adapted to the light, I saw some people in the light, all my friends and relatives who died. I feel very familiar with this place, just like I just left here for a while.

This place is as real as the world I left. Time and space are no longer an obstacle. It is a wonderful world full of joy. The pieces of life in the past are constantly passing by my eyes. Somewhere in my heart, a powerful voice said to me: “You have seen enough forever, but now it is not when you stay here, go back to the world.”

I looked up, calm and mirrored on the water, the tiny waves smacked on the pebbles on the shore of the lake. I was lying on the shore of Lake Michigan, less than a metre from the water, feeling good, just like I just slept. A good feeling.

Surgery (Janet’s sudden death experience)

Many sudden death experiences are induced during surgery. A woman named Janet experienced this sudden death experience during hysterectomy. A summary of Janet’s sudden death experience is as follows –

I had a cardiac arrest during the surgery, and the surgeon said it was caused by anesthesia. At the time, I saw my body lying on the operating table and heard the conversation between the surgeon and other staff around me. I looked at it all in a state of detachment. I realized that it was my body and realized that I would die. I would be separated from my husband and children, but I have no sorrow, no fear, only a sense of peace, because I know that I will be reunited with them sooner or later, just a matter of time. Then, I felt like I was walking through a tunnel and quickly entering the outer space, with a bright front. I stopped in front of this light, although I can’t see it, but I can feel the existence of the Creator. I began to look back on my life. I once suspected the existence of God, but now his existence is so real.

While perceiving the existence of God, I also heard beautiful music. I feel that my consciousness seems to be increasing sharply. I feel that I know a lot of things at this moment… Strangely, I don’t remember how I came back. I only remember to wake up in the ward after a day and a half.

Stress (Melney’s sudden death experience)

Melanie was under great pressure. One day she felt a splitting headache, so she lay down on the bed, doing some muscle relaxation and trying to calm herself down. After a while, she felt that she could no longer feel her body. Instead, she felt that she had left her body and floated above her body. Here is Melanie’s sudden death experience –

I left my body and suddenly there was a large bright, but not glaring. In fact, watching it gave me a feeling of tranquility, feeling that I was bathed in peace and love. I stared at the light for a while, then I returned to reality. I opened my eyes and sat up straight, and I made two points without doubt: the light is God, I remember the 11-year-old sudden death experience, that year I was in a tonsil removal Almost died during the operation.

There are many unbearable pressures in my life, but the sudden death experience has affected me a lot. Now I feel that I can cope with what kind of things I have because I feel that the light is always in my heart and protects me. Being hurt helps me to cope with everything, so that I no longer fear fear and no fear of death.

Falling from a height (Norman Paulson’s sudden death experience)

Norman once worked as a lineman at a telephone company. When he climbed the pole to work, he did not tie the seat belt in a hurry and fell from the sky. Here is his sudden death experience –

Suddenly I fell back and wanted to grab the pole or something with my hand, but everything was already late. “Oh, my God!” At that time, I was 9 meters off the ground. I fell at this height. I was killed or injured. I saw the poles slid in my sight, and then I fell down on the ground. I feel a bright light, just like the sun shines on my face, and everything goes to silence.

I felt like I was standing in the air, motionless, looking down at the familiar coastline of Santa Barbara. Gradually, I remembered what had just happened. The body that fell to the ground was lying down, maybe dead, and maybe seriously injured. Then, I flew to the north. The higher the flight, the higher my consciousness was leaving the earth. At this time, I remembered a lot of things. I remembered all my responsibilities in the world. I thought a lot. Finally I remembered my father and thought of it. I have to say goodbye to him before I leave. So I turned around, and there was a white light cluster swirling underneath, like a gleaming spiral staircase. I walked down the light ladder.

My body was lying under the pole and covered with a blanket, so I entered my body. I opened my eyes and saw a piece of concerned face leaning towards me.

Scientific research on sudden death experience
In general, the sudden death experience often occurs in the following clinical conditions: postpartum hemorrhage or surgical complications caused by myocardial infarction cardiac arrest (clinical death), infectious or anaphylactic shock, electric shock, traumatic brain injury or cerebral hemorrhage or Coma caused by cerebral infarction, attempted suicide, drowning or suffocation, apnea, severe depression, and so on.

Typical features of a near-death experience include: receiving information in a telepathic sense; feeling or realizing that you are dying; feeling calm, happiness, and painlessness; feeling that you are disappearing from the world; feeling your body from the outside In vitro experience, such as observing doctors and nurses to give first aid to their bodies; “tunnel experience”, that is, the feeling of passing through a certain passage or stairs; moving quickly toward the bright spot of the tunnel, or suddenly being in a bright light; met “White people” or other “spirits”, or reunited with dead relatives; reviewing their own life experiences; suddenly having an epiphany about the meaning of life or the nature of the universe; making decisions for themselves or others to return to their bodies, usually Reluctantly, and so on. Many people who have experienced the experience of sudden death think that this is of great significance to them, and that moments of joy and insight have forever changed their future lives. Many people think that they have seen the afterlife, and this experience enhances their beliefs and no longer fears death. For them, the near death experience is a real, clear and precious experience.

There are many research theories about the experience of sudden death. In 1981, the International Sudden Death Research Association was established, an organization that promotes scientific and scientific education on the physical, psychological, social, and spiritual aspects of the near-death experience. The organization published the Study on Sudden Death. Journals such as Peer Review and Vital Signs. Later researchers led and initiated the study of sudden death experience and introduced the near-death experience into academic research.

In the 1990s, the theory of biochemistry was put forward, arguing that dimethyltryptamine (also used as a psychedelic drug) released from the pineal gland in the brain when it was dying was the cause of the sudden death experience. In 2006, it was suggested that during the sudden death experience, the person could “see” the brain’s scan of his life’s memory to find the memory stored in the brain that is comparable to the ongoing death experience, and all the scan information. It will be remembered permanently by brain activity. The theory also believes that the in vitro experience associated with the near-death experience is an attempt by the brain to combine sensory-acquired information with the experience or knowledge stored in the brain to create a fantastic scene for itself and the surrounding environment. .

Some neuroscientists believe that physiology can be used to explain all symptoms of sudden death experience. Studies have shown that the sudden death experience of patients with clinical death is a mental and pathological symptom caused by severe brain damage caused by the cessation of blood circulation in the brain. Studies have shown that the sudden death experience of most patients who have been declared clinically dead but survived can be explained by a purely physiological cause of hypoxia in the brain. Some sleep researchers have suggested that dreaming may also be a factor in the experience of sudden death – some sudden death experiences are similar to those of lucid dreams, probably because of the physiological and psychological stress generated during life and death. The brain’s vagus nerve triggers the brain to produce a state similar to that of a lucid dream, and as a result, some people who love to be lucid dreams are more likely to experience a near-death experience. In a study conducted in 1991 for 14 lucid dreamers, the testers had a similar experience of ex-vivo, such as feeling that they had left their body and floated above the bed.

Recently, Kevin Nelson, a well-known American brain specialist and professor of neurology at the University of Kentucky, presented a compelling new theory about the experience of sudden death. Nelson has been studying the near-death experience for more than 30 years. In his new work, The Pulse of God, he uses a theory he calls “the boundary of consciousness” to explain all the phenomena of sudden death.

After investigating 55 people with a near-death experience, Nelson found that 60% of them had a “REM invasion” in the past. REM sleep is rapid eye movement sleep in sleep, which is the most time we dream of sleeping. Nelson pointed out that the brains of the experience of the sudden death experience are not directly converted between the REM state and the awake state, but are more inclined to fuse the two states together. This is what Nelson calls the boundary of consciousness. “. He believes that many people will enter this “location of consciousness” a few seconds or minutes before entering REM sleep state or before waking up. He said that at the “boundary of consciousness”, there are limbs, lights, illusions and lifelike dreams. As some people say, they saw the dead relatives, saw the light, the tunnel, and met God.

Nelson uses the way the brain works to explain the near-death experience. In his research, he found that the sudden death experience occurs at times of life and death such as fainting and cardiac arrest. The vast majority of sudden death experiences have one thing in common, that is, the brain’s blood supply is temporarily interrupted. Nelson said that usually 20% of the blood pumped by the heart is needed to keep the brain working. If blood flow is reduced to 1/3 of normal supply, the brain can remain active for a short period of time, but after 10 to 20 seconds, the brain loses consciousness. Most of the sudden death experience is a reaction of the brain to a decrease in blood supply. During the period from the loss of blood to the loss of consciousness, human consciousness may drift between possession and loss of consciousness. The most sensitive body tissue for this is not the brain, but the eye, specifically the retina of the eye. When the retina gradually becomes inoperable, the darkness comes along, and the process goes from the outside to the inside, eventually producing a unique tunnel-like visual perception.

Nelson believes that there may be two sources of light at the end of the tunnel: one from the surrounding environment, such as the background light in the emergency room of the hospital, which may be something the brain can recognize when the blood is gradually lost from the head; It is derived from rapid eye movement, which powerfully activates the visual system and produces a sense of light inside the brain.

Nelson’s explanation for the experience of the experience of the sudden death experience is that the dome that is responsible for perceptual movement is the area of ​​the brain that is related to the in vitro experience. When REM sleeps, this area is usually closed. However, this function will be abnormal in some cases, so the brain perceives the movement during the transition to rapid eye movement.

Nelson’s explanation for the sudden death experience that floats outside the body is that it is a feeling that sleepers develop muscle activity during REM sleep, and it is a mechanism for the body to avoid making intense action in sleep. .

In order to make a scientific explanation of the soul’s floating air, Nelson cited a study by Swiss neuroscientist Olaf Blanco, a surgeon who used surgery for a woman with epilepsy. The electric pulse stimulates her brain to find out where the lesion is. The woman suddenly said that she had been out of the body, floating in the sky and looking down on her body. When the electrical stimulation stopped, she said she returned to her body again. Nelson’s explanation for this is that the woman’s in vitro experience is related to electrical stimulation. Once the electrical stimulation disappears, the feeling of ex-vivation disappears.

Nelson also attributed the happiness of the near-death experience to the brain’s reward mechanism. He said that in times of extreme crisis, the human body releases a chemical that gives people a sense of relaxation and happiness. This is a strange phenomenon in the process of evolution. Its roots can be traced back to prehistoric times – a group of prehistoric hunting The primitive man, when the encounter with the beast has no way to escape, if the victim who is caught has a sense of relaxation in such a critical moment, without fierce resistance, the beast will spend time and energy to deal with this less difficult to deal with. Others will have more opportunities to avoid the same fate and escape.

For more than a decade, there have been more and more reports of the experience of sudden death, and some scientists have begun to accept the reality of sudden death experience. Whether the experience of the sudden death experience is “meeting God” or just an illusion, the fact is that many experiences of the experience of the sudden death experience have fundamentally changed their lives, usually as follows: reduced death Anxiety, no longer keen on the pursuit of material life, to look at life with a calm mind. It is this phenomenon that the sudden death experience finally caught the attention of scientists. However, they study the near-death experience not to prove the existence of the afterlife, but to understand more about the human brain, mind and elusive happiness, and the process of death. If the experience of the sudden death experience can really benefit from this experience, then scientists should be able to find ways to deal with various psychological problems of human beings, from the relief of attempted suicide patients to the treatment of child abuse. Trauma and so on.

“The experience of sudden death” is not “spiritual”
Some neuroscientists pointed out in the early 1980s that the “sudden death experience” has the characteristic characteristics of a typical marginal leaf (a part of the brain) that can be explained by the release of endorphins and enkephalins in the brain.

Some neuroscientists suggested in 1983 that the release of endorphins can cause a “death experience” full of joy or emotion, while allyoxymorphone produces a “hell-like” near-death experience. The first formal “death experience” neurological model was proposed in 1987 and includes brain endorphins, neurotransmitters in the limbic system, and other brain parts.

In 1989, neuroscientists proposed a neurophysiological model of the “death experience”, arguing that serotonin plays an important role in producing a “death experience”. The study found that an anesthetic, ketamine, induces a “death experience.” By intravenous injection of a dose of ketamine, all the common contents of the “death experience” can be produced. In the 1990s, neuroscientists studied the hallucinogen dimethyltryptamine and proposed a hypothesis: a large amount of dimethyltryptamine released from the pineal gland in humans before or during sudden death. The cause of the phenomenon of sudden death.

In 2006, scientists passed through cardiovascular interventions, causing 42 healthy volunteers to experience fainting. Afterwards, these volunteers reported on the “death experience” of seeing light, tunneling, meeting relatives and visiting other worlds. In 2008, neuroscientists suggested that the “death experience” of clinical deaths is a mental dysfunction syndrome caused by a severe brain failure (caused by the cessation of blood circulation in the brain). Studies have also shown that hypercapnia (hypercapnia) in the blood can induce symptoms of “death experience” such as light, vision and mystical experience. There are also neuroscientists who suggest that the “death experience” is an illusion caused by cerebral hypoxia, drugs or brain damage.

The anesthesiologist Zola and his team at George Washington University in the United States believe that the “death experience” is caused by a surge in electrical activity caused by oxygen depletion in the brain before death. The degree of soaring is similar to that of a fully conscious person, but the former’s blood pressure is too low to detect, but it still produces vivid images and feelings. The gradual loss of brain activity occurs within approximately one hour before death and is interrupted by bursts of brain activity that last from 30 seconds to 3 minutes. The Zola team’s study of seven sudden death patients found that the increase in brain electrical activity occurred when blood pressure could not be detected. Their “sudden death experience” may be a memory of the total memory of synaptic memory, and dying. However, it is related to potentially reversible hypoxemia. A study released in 2010 said that the root cause of the “death experience” is that the high concentration of carbon dioxide in the blood changes the chemical balance of the brain, allowing the brain to “see” things.

In the “death experience”, the left temporal lobe activity of the brain increases. Stimulation of temporal lobe is known to induce hallucinations, “soul out” and memory flashbacks. In an experiment with one patient, electrical stimulation of the left temporal apical junction resulted in the patient’s illusion that another person was close to her. In 2011, an article published in the famous magazine Scientific American concluded that “the scientific evidence shows that all the features of the “death experience” have the roots of normal brain function errors.”

Some scholars claim that part of the “death experience” case occurs when the EEG is flat (ie, the brain is no longer functioning). However, some scholars have noticed that EEG is not a reliable indicator of brain death, because it can only detect half of the activity of the cerebral cortex, but it is not visible to the deeper cerebral cortex structure.

Many people who have experienced the “death experience” regard it as evidence of the existence of “post-mortem life” (“afterlife”) or “post-death consciousness”. The idealist claims that the “death experience” is evidence that “dematerialized consciousness” or “soul” exists separately from the flesh. However, materialists have pointed out that although physiological factors such as brain damage, intracranial hypoxia or hypercapnia are not sufficient to explain the full nature of the “death experience”, this does not overturn the scientific conclusion that only the living human body can produce consciousness. The idealism is simply untenable.

Scientists who have a negative attitude toward idealism point out that there is so far no evidence to support the existence of life after death. However, some studies have found that even during the period of unconsciousness, the brain can still record the impression. For example, in an experiment conducted in 1983, scientists used a vocabulary tape to test the memory of an anesthetized patient. After physical rehabilitation, these patients were able to identify which words appeared in the vocabulary that was played to them at a time that was significantly higher than the proportion of sporadic cases. The explanation for this is that even under the condition of total anesthesia, the brain still retains some of the ability to store new information. The “auditory” content accompanying “visual” in the “death experience” is likely to be related to this.

Scientists who don’t believe in “post-death consciousness” and “afterlife” also point out that the inference of the brain’s complete cessation of activity in clinically dead patients and the inference of the sudden death experience after brain death are untenable. In fact, most of the brain activity will not occur during the patient’s cardiac resuscitation attempt, as it takes too much time to save lives. So there is a possibility that even if the EEG shows a flat line (ie the patient has brain death), the patient still has brain activity, which is performed by functional magnetic resonance imaging, positron emission tomography or computer aided A tomography scanner can be explored because, unless it is directly connected to the brain through surgery, the electroencephalograph mainly measures the surface activity of the cerebral cortex.

In short, the mainstream scientific community still does not support the so-called “post-death consciousness”, and even less agrees with the existence of “soul.” In fact, although the scientific community still has controversy about the concept of consciousness, the standard of death, and the “death experience”, the mainstream view is still the material decision consciousness, and there is no consciousness without life.

Thinking about the experience of sudden death
Research on the experience of sudden death, whether in foreign countries or in China, is not news. However, not all scientists are convinced of the results of the exploration of the near-death experience. In particular, the facts from the “death test”, “hell investigation” and “death and resurrection” have been opposed by some scientists.

Russell Noyce, a professor at the Los Angeles City School of Medicine, believes that the traditional Freudian psychological curve seems to express this peculiar near-death experience. However, he still cannot be clearly stated in theory.

The two professors at the Massachusetts Institute of Technology believe that the five stages of this sudden death experience are purely nonsense. The so-called “death experience” is the illusion of death caused by suffocation, which is caused by the lack of feeling.

The so-called sudden death is a persistent deep coma, loss of consciousness, and respiratory arrest.

However, the thinking activity is not completely over, it is still going slowly, so it will produce dreams.

When people wake up from a deep coma, they often keep a memory of this dream.

The biologist Roland Sig explains from a biochemical point of view that he believes that when everyone dies, the brain secretes excess chemicals, which can sometimes cause strange hallucinations.

Among all scientific explorations, the most convincing is the theory put forward by some scientists: These five stages are actually subjective experiences in a short time when people are coming to death.

The first stage is the instinct of individual protection and defense of the deceased. Because under the threat of death, excessive sorrow, fear and tension will accelerate the consumption of human energy, so that death will come faster.

The second stage is that the deceased do not want to die prematurely, trying to deny the feeling that they have entered the gates of hell and symbolically escaped the pain in the body.

The third stage is actually the recovery of the memory of the death of the dead, which is a special function caused by the special cells of the human body. The black hole is actually the birth path of the mother. The experience of penetrating the black hole is the experience of being pushed to the human world through the mother’s birth canal at birth.

The fourth stage is the self-consolation and hallucinatory satisfaction of the deceased, instinctively to eliminate the frustrations of sitting and waiting, while repeating one’s life to give them a sense of permanence. The gathering with friends and family is a retreat from the fear of death.

The fifth stage is the exploration of the potential knowledge domain of the dead, which is a special manifestation of the inspiration response in the human body.

In these scientific discussions, there is a striking situation in which some scientists try to explain the near-death experience with Indian yoga.

They believe that the fifth stage of dying has many striking similarities with the “Kindane awake state” in yoga. “Gentani awake state” is a technical term for a superhuman state.

They believe that there is a huge reservoir of energy in the middle of each person’s spine to the middle of the pelvis. This is the “Gendani”, which is a “snake of life” that is strong in human beings and deeply hidden in the human body.

For thousands of years, there is a legend among the yoga believers that “Gentani” can wake up in the following ways: When you rush toward a mysterious light, you will reach the “Kindani awake state.”

As early as 1982, Professor Reinger of the United States conducted a joint study with the director of the “Gendani Research Center” in Toronto, Canada.

They raised the question: Yoga fans are diligently exercising and pursuing their lives, and it is difficult for someone to really get the superhuman skills. However, those who have experienced the fifth stage of the near-death experience have easily acquired this superhuman ability. Why is this?

After research, they wrote a monograph that reflects the results of this research – “Super-Wisdom People.” The book expresses the following points:

Modern human beings are living in the decisive stage of the development of the universe. Mankind will have more profound and important changes than the Neolithic Age more than 10,000 years ago.

The near-death experience may be a mechanism of change. At present, this change only affects the dead, but it is a sign that humans will leap to a new state.

In this new situation, the various spiritual potentials and specific functions of human beings who have been sleeping so far will be released, and human beings will truly become superhumans in fantasy.

They also wrote in the book:

Since the Neolithic Age, the essence of humanity has not changed, and the development of the universe has required human beings to be more capable.

The fifth stage of the sudden death may be the model of the future human being, that is, the super-wise person. Many sociologists believe that the emergence and rendering of this peculiar phenomenon is actually a product of a deformed society.

However, the human death mentality is indeed a natural mystery, it needs to be explored and studied by human beings.

Studying the near-death experience can not only deepen the understanding and understanding of this natural mystery, but more importantly, help to save, comfort and care for the deceased, help them get rid of the danger and create a miracle of “returning to life.”

In addition, you can use the experience of sudden death to enhance the cherished and nostalgic value of the suicide of the attempted suicide, and get rid of self-blame, guilt, misery and suicidal thoughts.

At the end of 2000, British scholars completed the world’s first scientific research on the experience of sudden death, and found that the human consciousness, the so-called general soul, continued to exist after the brain stopped working.

The study found that the sudden death experience shared by four patients who escaped from life included the feeling of tranquil joy, the rapid passage of time, the feeling of the senses being stronger, no longer aware of the existence of the body, seeing a glare, entering Another world, encountering a mysterious spirit, and a place where there is no return.

It is expected that this research will lead to a long-standing debate between the church and the scientific community: “Life after death” really exists?

According to the British “Daily Telegraph” report, the neuropsychologist Fervik of the London City Institute of Psychiatry and the researcher of the Southampton Hospital, Pania, in a one-year study, 63 sudden heart attacks The patient who survived the death was observed for one week after the onset of the disease.

It was found that 56 people, as expected by the medical community, had no memory after losing consciousness, but 7 people still had memories after the heart stopped beating. Four of them passed the “Grayson Scale” to assess whether there was a sudden death experience. “.

Three of the four were not members of the Anglican Church who were not in church, and the other was a Catholic, and later no longer believe in religion.

The findings were published in 2001 in the highly respected medical journal Resuscitation.

Many scholars who criticize the experience of sudden death believe that the experience of sudden death is the result of the collapse of the brain due to lack of oxygen.

However, Fervik and Pania said that the four subjects with sudden death experience did not experience the state of hypoxia in the brain, so the lack of oxygen in the brain should not be the cause of the sudden death experience.

Another scholar believes that the experience of sudden death is the result of the doctor’s unusual combination of drugs given before the death of the patient.

But Fervik and Pania said that the recovery process of these patients in the hospital is exactly the same, thus eliminating the factors affecting the drug.

However, they still emphasize that it is necessary for the scientific community to conduct more research on the near-death experience.

Pania said that the experience of these four people is beyond the experience of the medical community. Their brains should not have the ability to keep their minds clear and form lasting memories. Therefore, this study may provide an answer to the following questions: Whether the mind and consciousness are the result of brain production, or the brain is just a medium of mind, and the mind is something that exists independently of the brain.

Vivik pointed out that if the mind and the brain are two things that exist independently, then consciousness may continue to exist after death, and the soul may exist. The universe may also be a meaningful and purposeful existence, not a Randomly occurring results.
