Apparently your brain might stay alive long enough to know youre dead
Steph Barnes,Hello
Death just became even more scary: scientists say people are aware theyre
dead because their consciousness continues to work after the body has
stopped showing signs of life.
That means that, theoretically, someone may even hear their own death being
announced by medics.
The claim was made by Dr Sam Parnia, director of critical care and
resuscitation research at NYU Langone School of Medicine in New York City.
He and his team are looking at people who suffered cardiac arrest,
technically died, but were later revived. Its the largest study of its type
ever carried out.
Some of those studied say they had awareness of full conversations and
seeing things that were going on around them, even after they were
pronounced dead.
These accounts were then verified by the medical and nursing staff who were
present at the time.
Death is defined as the point at which the heart no longer beats, and blood
flow to the brain is cut off.
Dr Sam Parnia said: 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.
However, theres evidence to suggest that theres a burst of brain energy as
someone dies.
In 2013 researchers at the University of Michigan looked at the electrical
signals inside the brains of nine anaesthetised rats having an induced heart
attack.
They saw activity patterns which are linked to a hyper-alerted state in
the brief period after clinical death.
Dr Parnia said: "In the same way that a group of researchers might be
studying the qualitative nature of the human experience of 'love', for
instance, we're trying to understand the exact features that people
experience when they go through death, because we understand that this is
going to reflect the universal experience we're all going to have when we
die."
