A new study indicates that when we die, we know we are dead because our brain continues to function and remains aware of what is happening.

Death has always intrigued humanity, and top scientists have always sought to know what happens when a human being dies.

There has been a great deal of research with anecdotal evidence of near-death and after-death experiences, and of people describing out-of-body experiences with lights and flashes of light.

A study based on survivors of cardiac arrest suggests that our consciousness remains active even when our hearts stop functioning and our bodies stop moving, according to The Sun.

Dr. Sam Parnia, Head of Cardiopulmonary Resuscitation Research and Adjunct Professor at the Stony Brook University School of Medicine, studies human consciousness after death and studies cardiac arrest cases in Europe and the United States. United States. He interviewed patients online about what they had seen and heard before coming back to life.

The Parnia study states that survivors of cardiac arrest were aware of what was going on around them when their heart had stopped beating and could describe their environment accurately later.

According to the Daily Mail of November 28, the Parnia study focused on what happens in the brain after cardiac arrest, to prevent brain damage when reworking the heart. He also tries to know how long the consciousness lives after the heart stops beating to improve the quality of resuscitation.

Parnia officially declared that a patient is declared dead when the heart stops working. "Technically, that's how you get the time of death," he said.

Then, the blood does not circulate in the brain, which means that brain function stops "almost instantly," he said, adding, "You lose all your brainstem reflexes – your nauseated reflex , your student reflex, all that has disappeared. "Parnia said that brain cell death usually takes place a few hours after stopping the heart.

CPR sends blood into the brain, he added. "If you manage to restart the heart, what is trying to do CPR, you will gradually restore the functioning of the brain. The more you practice CPR, the pathways of brain brain death continue to occur – they occur at a slightly slower pace, "he told the website.

And some people whose hearts had stopped before restarting remembered exactly what had happened to them.

"They will describe watching doctors and nurses work; they will describe having an awareness of whole conversations, visual things that would not otherwise be known to them, "he explained. These memories were verified by the nursing and medical staff present at his death.

They were stunned to learn that patients could remember these details, he said.

Some people who have returned can have a positive experience.
"What tends to happen is that people who have gone through those very deep experiences come back transformed in a positive way," said Parnia. "They become more selfless, more committed to helping others."

He added, "They found a new meaning in life after meeting death. But there is no sudden and magical improvement in their memories. It's just Hollywood jazz.

According to a summary of AWARE, or Parnia's AWAreness during resuscitation, study: "Survivors of cardiac arrest have cognitive deficits, including post-traumatic stress disorder (PTSD). It is not known if these experiences are related to cognitive / mental experiences and awareness during CPR. Despite anecdotal reports, the wide range of cognitive / mental experiences and awareness associated with CPR has not been systematically studied. "

Along with Parnia, Ken Spearpoint of Hammersmith Hospital, Imperial College, University of London; Gabriele de Vos Montefiore Medical Center, New York, USA; and Peter Fenwick, Southampton University Hospital, Southampton, United Kingdom; participated in the study with several others.

Out of approximately 2,060 cardiac arrest events, 140 survivors were interviewed. Forty-six percent "had in mind 7 main themes: fear; animals / plants; brilliant light; violence / persecution; already seen; family; recalling subsequent events[cariac arrest], Summarizes the summary. About 9% had near-death experiences and 2% "described their awareness with an explicit reminder of" seeing "and" hearing "real events related to their resuscitation. from them had a verifiable period of consciousness, during which one did not expect a brain function. "
