Research says the brain always works afterwards so you know about everything

The human brain always works after death, which means you know you are dead, according to new research.

Scientists say that they discovered that brain activity always works a few seconds after stopping the heart. Experts say that means that a patient would be fully aware of what was happening to him as his consciousness continues to function.

Scientists suggest that shortly after death, the person would be "trapped" in his dead body with the brain in function.

Survivors of heart attacks were aware of what was going on around them while they were clinically "dead" before being "brought back to life" and could describe what was going on around them. After their heart stopped beating, reveals the new study.

Researchers say evidence suggests that the deceased may even announce his death.

According to the DailyMail, Dr. Sam Parnia and his team at Stony Brook University's School of Medicine in New York have examined their consciousness after their deaths by researching cases of cardiac arrest in New York City. Europe and the United States.

He said that the study found that people often change after experiencing this "after death" experience and become more willing to help others.

But unlike the plot of the film Flatliners, which saw medical students doing experiments by resurrecting themselves after stopping the heart, the person does not come back to life with memories and visions, added Dr. Parina.

In the 1990 film starring Kiefer Sutherland, Julia Roberts and Kevin Bacon, as well as in a remake of 2017 with Ellen Page, trainee doctors are haunted by visions of their past.

But Dr. Parnia said that a resuscitated person would not come back with a "magical enrichment" of his memories.

Dr. Parnia told LiveScience: "They will describe having watched doctors and nurses work, they will be aware of being aware of full conversations, visual things going on, of which they would not otherwise be aware. .

"He [the time a patient is declared dead] is based on the moment when the heart stops. Technically, this is how you get the hour of death. "

Doctors determine the time of death when the heart stops and when that happens, brain function stops almost instantly, "added Dr. Parnia.

But he says the cerebral cortex of his brain, known as the "thinking part," also slows down and is flat, but brain cells can still be active for hours after the heart stops.

Performing a CPR on a person whose heart has stopped will send about 50% of the blood he needs to the brain, which, according to Dr. Parnia, is enough to revive his duties.

He added: "If you manage to restart the heart, as CPR attempts, you will gradually restart the brain.The longer you practice it, the more these cerebral cell death pathways continue to occur just at a rate. slightly slower.

"What tends to happen is that people who have gone through these very deep experiences come back positively transformed, they become more selfless, more committed to helping others, they find a new meaning to life after facing death do not like a sudden magical enhancement of their memories.This is only Hollywood jazz. "

His study examines what happens in the brain after a cardiac arrest, if the consciousness persists after the death and for how long.

The goal of the research is to improve the quality of resuscitation and prevent brain damage when restarting the heart.
