The body is not dead, will the brain still die, the body is dead but the brain is still alive

Brain death exists, as evidenced by vegetative people.

Basic physiological representations are maintained, and after neuronal failure or death, the body can be sustained for a period of time under the action of instinct.

Because the brain is in charge of the human body's thinking, and it can produce thoughts independent of the rest of the body. Therefore, even if the other organs of the human body have died, as long as the brain can have an adequate supply of nutrients, then the brain can continue to survive. Of course, you can continue to generate thoughts, so that you can live in the virtual world.

It will also consume a lot of money, and the pain will be **, so the more extreme development in the future is to directly put the brain in the nutrient solution.

under, for its consumption, while all analog signals.

Then there is an outside world to provide and become a real brain in a vat! In the future, the population of the society will skyrocket, which can be a solution to the problem, but this is only the choice of the general public, and the super-rich will still choose to leave the brain-computer interface lacking.

Come in and enjoy it when you want to do whatever you want in the virtual world, and leave the virtual world when you need guidance from real life!

Boltzmann. A kind of brain was once proposed - the Boltzmann brain. This brain is created out of thin air, and the probability of its occurrence is greater than the probability of natural evolution of us humans.

In other words, there may be volcanic leakage Boltzmann brains everywhere in the universe, and this kind of brain appeared not long after the universe, before us. And quantum mechanics.

tells us that consciousness causes the quantum wave function to collapse, and that the formation of the material world may be the result of consciousness's involvement. Then our world is likely to be this world of Boltzmann's brain consciousness, and we are just living in a virtual world.

Clinical death is the loss of all physiological functions.

Brain death is defined as a criterion for declaring death based on the permanent loss of function of the central nervous system in or above the brainstem. Brain death is different from "vegetative", "vegetative" brainstem function is normal, coma is only due to severe damage to the cerebral cortex or in a state of sudden inhibition, the patient can have spontaneous breathing, heartbeat and brainstem response, while brain death has no spontaneous breathing, is permanent and irreversible.

In the past, many countries have used "cardiac arrest", "absent breathing" and "zero blood pressure" as the criteria for death. However, with the development of medical technology, patients' vital signs such as heartbeat, breathing, and blood pressure can be reversed or maintained for a long time through a series of drugs and advanced equipment. However, if the brainstem is structurally damaged and destroyed, no matter what medical treatment is used, it will eventually lead to cardiac death.

Therefore, compared with cardiac death, brain death appears to be more scientific and the criteria are more reliable.

There is a term for medical death, which is called brain death.

If the engine of the car is broken, it is not considered a broken car.

Brain death is not human death, it refers to a state of loss of function of the whole brain, including the brainstem, which is not much found in a vegetative state, but it is different from a vegetative person.

A vegetative person is a brainstem function, and the person is only in a coma, mainly due to severe damage to the cerebral cortex or in a state of sudden inhibition, the patient can have spontaneous breathing, heartbeat, and brainstem responses, and maybe that day she can be woken up.

Brain death, on the other hand, has no spontaneous breathing and is permanent and irreversible.

Diagnostic criteria for brain death in China:

Brain death is an irreversible state of loss of skills throughout the brain, including the brainstem.

Prerequisites include: clear cause of coma, exclusion of reversible coma of various causes.

Diagnostic criteria: deep coma, complete loss of brainstem reflexes, no spontaneous breathing. All of the above must be present.

In the confirmatory test, the EEG was straight, the transcranial Doppler ultrasound showed a pattern of brain death, and the waveform of somatosensory evoked potentials above p14 disappeared. Must be positive in one of these three items.

All human physiological activities are governed by the brain, so when it is determined that the brain is dead, all the physiological characteristics of human beings have stopped. So there is no heartbeat and no breathing after brain death. In the past, it was always thought that the heart stopped beating as death, but now that medicine has developed, as long as the brain is not dead, the heart will beat again if the heart is rescued in time after the heart stops.

So modern medicine prescribes brain death as the end of a person's life.
