What Really Happens as We Die?

People who’ve been to the brink of death and back often describe an inexplicable state of heightened consciousness and awareness involving similar mental flashbacks and out-of-body experiences. While science can’t explain what’s going on or why, it’s become clear that the brain can remain active longer after the heart stops than previously thought, and death is not quite as final as once assumed.
There’s no agreed-upon scientific definition for near-death experiences, or NDEs. Studying them clinically is rather difficult, as you might imagine, so much of what’s known or presumed is based on people’s recollections of their NDEs — the stories they tell afterward. People often describe seeing bright lights or tunnels and feeling at peace. But in some cases, they recall being scared.
A comprehensive new review of studies on the topic — by 18 physicians, neuroscientists, psychologists and other researchers — does not advance the understanding greatly, but it offers a consensus view of what is known about what happens when we die, and when someone is really dead.
“Death is not an absolute state,” says study team member Sam Parnia, MD, director of…
