Death is the path that human beings must pass through in their lives, but people are always afraid of it, so they ignore it and prohibit talking about it. In our country, we are always stingy about death. We always substitute various "decent" words for death. words such as Xianqu, Shanling Beng, and Leaving, but we can use various grammars Covering up the traces of death cannot stop the pace of death. People are mortal, either lighter than a feather, or heavier than Mount Tai. Since there is no resistance, then there is only the process of enjoying life.
Tips: Death is a link in the natural circulation chain and an inevitable change in the world. The legacy of the post-death system is necessary material for other existing or new things.
But our nature is curious, we fear the unknown event of death, and we are also curious about what death is. Death is a road to the unknown. No one knows what kind of scenery or suffering there is on this road. Because of its mystery, it has attracted countless experts and scholars to study. Will the soul reincarnate after death? Does man have a soul? Does consciousness still exist after death?
What is the nature of consciousness? What is the relationship with death
I first knew the term consciousness in political classes. When the teacher talked about philosophy, he talked about the relationship between matter and consciousness. said that consciousness is a function of the human brain and a subjective view of the objective world. Image. But such a statement is too confusing. Simply put, consciousness is a person's perception of the environment and self, which is a kind of neural response.
Tips: The surface layer of the cerebral hemisphere is gray matter and the deep layer is medulla. The medulla contains nerve fibers and nuclei, and there are 4 pairs of nuclei located at the bottom of the brain called the basal ganglia (nuclei), including caudate nucleus , legume nucleus, amygdala and screen nucleus.
The early philosophers attributed consciousness to a kind of idea, so it was recorded in the "Jianjing Jing" as: "Virtue transforms love, love business, and perpetual movement." It means that virtue can evolve emotions, and love can give rise to emotions. Unexpectedly, consciousness is formed by constantly reversing the mind. In Buddhism, the mind is interpreted as one of the six consciousnesses in Buddhism, which is the consciousness arising from the root of mind. In the broad and profound Chinese, consciousness has the meaning of being aware and discovering. Until modern science defines it as a kind of human neural response, which is produced in the nervous system of the brain, so consciousness is with life.
Tips: This phenomenon also exists when a biological individual exchanges material or information with the external environment or the individual itself. Here we call it "reflection", also called nerve Reflection.
Since consciousness is with life, then why is there the proposition " I think so I am "? I think that I am conscious so I exist. If I think I am not conscious, then I am not conscious? Since consciousness comes from the nervous system of the human brain,Therefore, no matter how you perceive, as long as the nervous system is still active, then consciousness will always exist. However, in addition to the nervous system, the five senses of a person also determine the production of consciousness. If a person’s five senses are closed, not listening, not seeing, not smelling, not speaking, and not touching, then even if the nervous system is still active, consciousness cannot be generated. . Therefore, the essence of consciousness is a comprehensive ability that integrates the brain and the five senses.
Tips: Consciousness is the human brain's perception of the internal and external appearance of the brain. Physiologically, the conscious brain area refers to the conscious brain area that can obtain information from other brain areas, around the prefrontal lobe.
So what is the relationship between consciousness and death? Consciousness is produced by the nervous system, and death heralds the cessation of the nervous system. Therefore, death and consciousness can be said to be a compliant relationship in theory. But in the latest research, researchers found that after death, consciousness can still exist for a period of time. What is going on?
Research shows that there is still consciousness in the first stage of death
Dr. Sam Parnia is an associate professor in the Department of Medicine, New York University Grossman School of Medicine, yes, majoring in clinical medicine Many times of first aid experience brought the dying patient back to the world. In many first aids, the doctor came up with an idea. He wanted to know what the human consciousness saw during the dying period. Will consciousness still exist after death? Therefore, he conducted a series of experiments to verify his guess.
Tips: First aid refers to when there is any accident or sudden illness,Before the arrival of the medical staff, the rescuer will use the available materials on the spot to provide temporary and appropriate initial rescue and care for the injured and sick according to the principles of medical care, and then rush to the hospital.
Dr. Sam Pania conducted this experiment at Southampton General Hospital. spent a year searching for 63 cardiac arrest survivors and conducting research on them. Most of the patients claimed to have seen hallucinations when they were dying, but Sam found in the study that only 11.1% (7) of the survivors claimed to have hallucinations. However, after further research, they found that they truly corresponded to . There are only 4 people with death experience , and the rest are either inconsistent with near-death experiences or no memories. Therefore, experiments have proved that among cardiac arrest survivors, very few people retain their memories. Patients with memories claim to have seen their lost relatives or are soberly aware of what is happening around them, and some even feel that they are leaving their bodies. Bondage.
Tips: Cardiac arrest refers to the sudden termination of the ejection function of the heart, the disappearance of aortic pulsation and heart sound , severe ischemia and hypoxia in important organs (such as the brain), leading to the end of life.
But his words were unprovoked, so Dr. Sam carried out another experiment. He wrote a number on the floor of the hospital operating room and asked the survivors of cardiac arrest if they were conscious after giving first aid to the patient. The feeling of being out of the body, if any, see the numbers on the ground. If you really consciously leave the body, you can see the numbers on the ground from above the body, thus proving the existence of consciousness. On the contrary, if you don’t know what the number is, it means that all you see during the near-death experience are hallucinations.Although the conclusion of this experiment is not very firm due to the scarcity of samples, Dr. Sam believes that it reveals the relationship between the brain and consciousness.
Tips: hallucination hallucination refers to the perceptual experience that occurs when there is no corresponding objective stimulus. In other words, illusion is a subjective experience, and the subject's feeling is similar to perception. This is a serious perceptual disturbance.
Dr. Sam believes that dying patients can perceive what is happening around them during the dying process before being rescued. After the brain stops beating, consciousness can still exist for a period of time, even if this period of time is very short. In medicine, we usually think that if the heart stops beating, it is death. Therefore, consciousness still exists in the first stage of death and can perceive the passing of life. Dr. Sam is also studying the effects of cardiac arrest on the long-term quality of life, and whether there are changes in the brain after cardiac arrest. In short, Dr. Sam’s conclusion is that consciousness still exists after death, and that the brain and consciousness are causally related, brain nerve activity, consciousness exists, and vice versa, consciousness does not exist.
Tips: near death, that is, dying. Refers to patients who have received curative and palliative treatments, although their consciousness is clear, but their condition has accelerated. Various signs indicate that life is about to end.
Coincidentally, in 2013, the University of Michigan discovered when studying the activities of dying mice that the high-frequency brain waves were extremely active when the animals were dying. This experiment was led by Professor Peer Zhijin Jimo. During the experiment, it was found that the brain waves plummeted after the rat’s heart stopped beating.But the frequency is increasing, and the electric waves in different parts of the brain begin to resonate very strongly, which means that consciousness still exists.
That is to say, at the moment of death, although the brain waves of the mouse seem to be low, it is very vigorous and has stronger consciousness than when it is awake. Therefore, at the moment of dying, there will be a process that is more real than reality. also proved that consciousness has a strong sense of existence in the first stage of death, and can clearly perceive one's own death.
Is death really that terrible?
Death is the focus of life and the ultimate destiny of mankind. However, for a long time, people have always reported fear of death and dared not discuss it with others. This may be the fear of death due to the unknown, perhaps it is due to religious and cultural reasons, or it may be due to psychological reasons.
Tips: Electroencephalogram of brain waves is a method of recording brain activity using electrophysiological indicators. When the brain is active, a large number of synchronously generated postsynaptic potentials formed by a large number of neurons are formed after the sum.
The word death seems to be born with mystery, pain, disillusionment and nothingness. People don't know how to deal with death, so they just keep silent. The end result is that when facing death, he is at a loss, and then crying and regretting for life. But is death really that terrible? Rather than when death comes,Only to cry and regret it, it is better to understand death earlier.
The normal death process, relatively quiet. During this process, the patient will gradually feel tired. As time goes by, the patient will sleep more and wake up less, and sometimes fall into an unconscious coma, but this is not terrible. In the process, the patient feels a long-lost relaxation . One day after that, they left peacefully in their sleep. All this is very peaceful.
Tips: Coma is a type of complete loss of consciousness and is a clinically critical illness. The occurrence of coma indicates that the patient's cerebral cortex function has been seriously impaired.
As a philosopher said, death is just a transition to another life, and you should bless happily!
