But our nature is curious, we are afraid of the unknown event of death, and we are also curious about what death is. Death is the 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 it. Will the soul be reincarnated after death? Does man have a soul after all? Does consciousness still exist after death?
What is the essence of consciousness? What does it have to do with death?
The term consciousness was first recognized in political class. When the teacher talked about philosophy, he talked about the relationship between matter and consciousness. Consciousness is the function of the human brain and the subjective image of the objective world. But this statement is really awkward. Simply put, consciousness is people's cognition of the environment and self, and it is a nerve reaction.
Early philosophers attributed consciousness to an idea, so it was recorded in simple classics as: "Moral love, love career, keep moving forward." It means that virtue can evolve feelings, feelings can lead to accidents, and consciousness is formed in the constant reversal of meaning. Among Buddhists, concept is interpreted as one of the six senses of Buddhists, which is knowledge from the root of meaning. In esoteric Chinese, consciousness also means awareness and discovery. Until modern science defined it as a nervous reaction of human beings, it originated from the nervous system of the brain, so consciousness and life coexist.
Since consciousness and life coexist, why is there such a proposition as "I think, therefore I am"? I think I am conscious, so I exist. I think I'm in a coma, so I'm in a coma? Because consciousness comes from the nervous system of the human brain, no matter how you perceive it, as long as the nervous system is still active, consciousness always exists. However, in addition to the nervous system, human facial features also determine the generation of consciousness. If a person's five senses are closed, they can't hear, see, smell, say or touch, then even if the nervous system is still active, they can't produce consciousness. So the essence of consciousness is the comprehensive assembly ability of brain and five senses.
So what is the relationship between consciousness and death? Consciousness is produced by the nervous system, and death indicates the cessation of nervous system activities, so death and consciousness can be said to be an inheritance relationship in theory. But in the latest research, researchers found that consciousness can still exist for some time after death. What happened?
Studies show that the first stage of death is still conscious.
Dr. sam parnia, an associate professor in the Department of Medicine of Grossman School of Medicine of new york University, specializes in clinical medicine and has a lot of first aid experience, which will bring dying patients back to life. During many times of first aid, the doctor came up with an idea. He wants to know what people's consciousness sees when they die. Does consciousness still exist after death? Therefore, he carried out a series of experiments to verify his guess.
Dr Sam Pania conducted the experiment at Southampton General Hospital. He spent a year searching for 63 survivors of cardiac arrest and studying them. Most patients claimed to have seen hallucinations before they died, but Sam found in his research that only11.1%(seven survivors) claimed to have hallucinations, but after in-depth research, it was found that only four of them really met the near-death experience, and the rest either did not meet the near-death experience or had no memory. Therefore, experiments have proved that few survivors of cardiac arrest have retained their memories, while patients with memories claim to have seen their lost relatives or clearly know what happened around them, and some even feel that they are getting rid of the shackles of their bodies.
However, there was no evidence in his words, so Dr. Sam conducted another experiment. He wrote a number on the floor of the hospital operating room. After giving first aid to the patient, he asked the survivors of cardiac arrest whether they had consciously left their bodies. If so, did they see the number on the ground? If you are really conscious, you can see the numbers on the ground from above your body to prove the existence of consciousness. On the other hand, if you don't know what this number is, it means that what you saw in the near-death experience is an illusion. Although the conclusion of this experiment is not very stable because of the scarcity of samples, Dr. Sam thinks it reveals the relationship between brain and consciousness.
Dr. Sam believes that dying patients can perceive what is happening around them before they are rescued. After the brain stops beating, consciousness can still exist for a while, even if it is short-lived. In medicine, we usually think that cardiac arrest means death, so consciousness still exists in the first stage of death, and we can feel the passing of life. Dr. Sam is still studying the effect of cardiac arrest on the long-term quality of life and whether there are any changes in the brain after cardiac arrest. In a word, Dr. Sam's conclusion is that consciousness still exists after death, and there is a causal relationship between the brain and consciousness, and there is neural activity in the brain, but consciousness does not exist.
Coincidentally, in 20 13, when studying the activities of dying mice, the University of Michigan found that animals were extremely active in high-frequency brain waves when they were dying. This experiment is led by Professor borjigin Jimo. In the experiment, it was found that after the heart stopped beating, the brain waves of mice plummeted, but the frequency increased, and radio waves in different parts of the brain began to produce strong * * * sounds, indicating that consciousness still existed.
That is to say, at the moment of death, although the brain waves of mice look very low, they are very energetic and more conscious than when they are awake. So at the moment of dying, there will be a more real process than reality. At the same time, it also proves that consciousness has a strong sense of existence in the first stage of death and can clearly perceive its own death.
Is death really that terrible?
Death is the focus of life and the ultimate fate of mankind. However, for a long time, people have been afraid of death and dare not discuss it with others. This may be caused by fear of unknown death, religious and cultural reasons, or psychological reasons.
The word death seems to be born with mystery, pain, disillusionment and nothingness. People don't know how to face death, so they just keep silent. The end result is that in the face of death, I am at a loss, and then I cry and regret for life. But is death really that terrible? It is better to know death earlier than to cry and regret when facing it.
The normal death process is relatively calm. In this process, patients will gradually feel tired, sleep more and more, wake up less and less, and sometimes fall into unconscious coma, but this is not terrible. In this process, patients feel a long-lost relaxation. Then one day they left peacefully in their sleep. Everything is calm.
As a philosopher said, death is only a transition to another life, so you should bless it happily!
