Scientists discover your mind still works when you die

Ellen Page stars in Flatliners in which medical students embark on a daring and dangerous experiment to gain insight into the mystery of what lies beyond the confines of life Scientists discover your mind still works when you die

What this means, according to CBS contributors, is that "in many cases they can be aware that they've passed away".

Parnia told Live Science that his team is looking at large numbers of people who have suffered cardiac arrests to figure out what they've gone through when their hearts stopped.

"Technically, that's how you get the time of death - it's all based on the moment when the heart stops".

Most people consider a person dead when their heart stops, Parnia told Live Science.

In the film a group of young doctors embark on a risky experiment by taking turns to chemically induce their heart to stop and flatline to find out exactly what happens in the afterlife.

A team from the New York University Langone school of Medicine, conducted a similar experience through twin studies in the USA and Europe, using people who have suffered cardiac arrest and "came back to life", as case studies.

Well, a new study suggests that our brains still continue to work after our body shows no signs of life.

"These are not return-from-death experiences", Kevin Nelson, a neurologist at the University of Kentucky, said at a conference, reported National Geographic.

These accounts were then verified by the medical and nursing staff who were present at the time.

8 crushed to death in TN roof collapse
Building collapses are common in India, and are largely caused by shoddy construction materials or lax oversight of regulations. In September, four people died and seven injured when the concrete roof of a bus stand in Coimbatore collapsed.

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.

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.

This sparks a chain reaction of cellular processes that will result in the death of brain cells.

Some attribute this after-death or near-death experience not to a true awareness but to a surge of activity in the brain that comes from a lack of oxygen, called hypoxia.

In the new research, NYU physician Sam Parnia said that after the patients were resuscitated, they were able to accurately recount conversations that had occurred after their hearts had stopped and describe conditions that existed around them during that period.

In the movie, a group of students take turns giving themselves a cardiac arrest to see what happens after their hearts stop.

But brain cell death is still happening, just at a slightly slower rate, he said.

Some of those studied revealed that they had awareness of full conversations and seeing things that were going on around them, even after they were pronounced dead.
