Remember the film Heaven is For Real? In it, four-year-old Colton Burpo has a near death experience during an emergency surgery and tells his skeptical father that he met his great-grandmother, his unborn sister who died from a miscarriage, as well as Jesus Christ himself. This, of course, is in addition to having seen everything that was happening to him while he was on the surgery table.
Heaven is For real was a for-real hit, raking in over $90 million on a $12 million budget. Its success rested on one thing. People are fascinated with near death experiences.
What happens when we die? That is one of life's enduring mysteries. Philosophers, priests, scientists – all schools of intellectuals have taken crack at this all important question. After all, everyone wants to know their fate after death.
In the largest study of its kind, Parnia's team assessed patients who had been declared dead due to cardiac arrest, but were later revived. The results were shocking.
A significant percentage of participants recalled being aware of their surroundings during the time they were technically dead. In fact, 39% of people studied described being aware of their surroundings, with a smaller percentage even describing what was said and done in the time they were dead.
As Parnia states.
Technically, that's how you get the time of death – it's all based on the moment when the heart stops. Once that happens, blood no longer circulates to the brain, which means brain function halts almost instantaneously. You lose all your brain stem reflexes – your gag reflex, your pupil reflex, all that is gone.
Jason Braithwaithe, a professor at the University of Birmingham in the United Kingdom spoke to the BBC about this phenomenon. “This is a very neat demonstration of an idea that's been around for a long time," Braithwaite said.
Under certain unfamiliar and confusing circumstances — like near-death — the brain becomes overstimulated and hyperexcited. Like ‘fire raging through the brain’, activity can surge through brain areas involved in conscious experience, furnishing all resultant perceptions with realer-than-real feelings and emotions."
In an interview with the BBC, the lead behind the study, Michigan State professor, Dr. Jimo Borjin, explained,
This can give us a framework to begin to explain these [near death experiences]. The fact [that people] see light perhaps indicates the visual cortex in the brain is highly activated - and we have evidence to suggest this might be the case, because we have seen increased gamma in area of the brain that is right on top of the visual cortex.So those visions people have during near death experiences may not be false after all.
While this is all very exciting, however, researchers have long known that the body's cells die off at different rates.
People think your hair and nails grow after death, but in reality, your skin begins losing moisture due to lack of blood flow. As the skin shrinks, more and more of the nail bed and hair follicle are revealed, leading to the misconception that both are still growing.
