Brains May Continue to Function Even After Death, Study Finds

According to Daily Mail UK, Dr Sam Parnia, a scientist, has revealed details of his research which claims that human beings remain conscious even after they have been confirmed dead by doctors.

During the evaluation, many patients were able to recall full conversations and visuals that occurred after they were pronounced dead, Parnia told Live Sciencein an interview.

Researchers at New York University's Langone School of Medicine claim the mind continues to be aware of what's happening, even when the body has stopped showing any signs of life.

A team from New York University Langone School of Medicine investigated the very same question through twin studies in Europe and the USA of people who have suffered cardiac arrest and "come back" to life, in the largest study of its kind. However, this can take hours after the heart has stopped, he explained.

Parnia and his team are using these accounts from people who've been "brought back" to learn more about a odd phenomena that takes place in the brain at the time of death.

But the reality of near-death experiences has always been debated. The accounts were confirmed by the medical staff who were present at the time.

The blood supply to the brain immediately cut off as soon as the heart stops beating and this will be the official time of death of a person.

This time, he weighed in on a dense 33-page statistics document, extrapolated a single crime number and linked it to " radical Islamic terror ".

Dr. Sam Parnia told Live Science "Technically speaking, that's how you get the time of death - it's all based on the moment when the heart stops".

The cerebral cortex of the brain, known as the thinking part, additionally backs off, then flatlines - no visible brainwaves on the electric screen - within two to 20 seconds.

They want to learn how the experiences of people who report having had consciousness after they were "dead" are related to their actual brain activity.

The New York team hopes the experiences of resuscitated patients will give them the vital clues about what the brain is doing before stops functioning.

The research explains that the medical definition of death is when the heart stops beating. This is enough to slow the brain cells' death trajectory, but it isn't enough to kick-start the brain into working again, which is why reflexes don't resume during CPR, he said.

Parnia performed a similar study in 2014, The Telegraph reported.

Some also talked about feeling peaceful or protected, a theme commonly found among those who have reported near-death experiences in which they've been clinically dead but then revived, Scientific American reported.
