After a person dies, does the brain still have consciousness for a short time?

Everyone will experience death. At the same time, it can be said that every kind of creature and life body will experience this process of death. This is the law of "natural world". Life is equivalent to a stage, there are moments of life and death, so this research result is announced. After coming out, it caused heated discussion among everyone, mainly because people want to know how to detect death after death, and there is consciousness.

Indeed, for a long time, experts have been discussing what happens after a person’s death. The most intuitive thing we can see is a change in the human body, but is there anything else in the process of actuality? No one knows the transformation process, such as whether a person consciously exists after death.

However, this study in the United States proved this problem, that is, when the human heart stops beating, the brain will continue to function, so after death, the brain will realize the fact that it has died, that is, know that it is dead.

Of course, this research is actually unreasonable from a different perspective. Why do you say that? Because death is divided into two situations, heart death and brain death

Heart death—Heart death refers to the stop of heartbeat before the complete stop of breathing and brain function. At this time, part of the way of judging death is based on the heart, but breathing and brain function are not stopped. This is the time to judge At the time, it means that there is indeed a conscious existence, because breathing and brain are both active, but after the death of the heart, the breathing and brain will also die quickly, so this process is actually a "short-term" conscious existence.

Brain death-Brain death is the loss of life of living things. It is the inevitable destination of the development of all living organisms. This death is established after the death of the heart. If consciousness is judged through brain death, it must be a different conclusion, so people will still have it after death. Consciousness can only say that it can only be explained after the death of the heart, and you also know that you have been declared dead. This is the general situation. From the research situation, it is a research result of heart death.

Indeed, in the state of cardiac death, it can be explained, and in this process, there must be a process of being rescued, a state at the time of death, and people in cardiac arrest must also know themselves. What happened, so based on this research, there is even some evidence that the deceased can even hear doctors announcing that they are dead, and people who have experienced cardiac arrest also hear doctors announcing the time of their death.

So this is a short-lived situation, but it can't be expressed, because when I receive this information, I may not have time to think, and my consciousness is gone. So this is mainly a division of death in science. At the same time, for both cardiac arrest and brain death, there have been people arguing about what constitutes real death. Some scientists have divided the stages of death. Different stages behave differently, and this process also occurs.

However, this research has not yet appeared on what happened after brain death. The above research is also based on brain activity, so if you know what happened after brain death, it is really amazing. Obviously it is not. Possibly, because brain death means that some functions of the body are all stopped, how to resurrect? There is absolutely no way to explain this in science, so the resurrection of frozen humans that everyone is talking about is basically impossible. Although it is established in a state of inhibited brain activity, in fact, this state may be no different from brain death.

This is why, after many frozen people have been frozen today, they have not seen any technology that can thaw people and then resurrect them at a certain period of time, because this is not possible in science. As for the future We don't know whether it can be done, but at least in today's science, there is no such way. Technology hasn't reached this strength, and the resurrection is similar to "science fiction."

Whether a person has consciousness within a short period of time after death is related to the criteria for judging death. One is heart death and the other is brain death. Therefore, there is a difference between the two, and which method is used to carry out death. Judging, there is no definitive statement yet, and this is also a controversial point of consciousness after death. We can only use this as a reference. This American study is only a targeted research conclusion, and this is the general situation.
