Welcome to the afterlife... for a few seconds! Bf3ore CPR is performed !
The human brain still functions after death, meaning you know you are dead, new research claims.
Scientists say they have discovered that for seconds after the heart stops, brain activity still functions.
Experts say this means a patient would be fully aware of what was happening to them as their consciousness keeps working.

For
a short time after death the person would be 'trapped' inside their
dead body with the brain still functioning, scientists suggest.
Survivors
of heart attacks were aware of what was going on around them while they
were clinically 'dead' before being 'brought back to life' and could
describe what was happening around them after their hearts stopped
beating, the new study revealed.
Evidence to suggest the deceased may even be able to hear themselves being pronounced dead by doctors, researchers claim.
Dr. and his team , examined consciousness after death by researching
cardiac arrest cases in Europe and the US.
He
said the study found people often change when they have had this
'after-death' experience and become more willing to help others.
But
unlike the plot in a movie, which saw medial students
carry out experiments by resuscitating themselves after stopping their
hearts, the person does not come back to life with memories and visions,the
Dr. added.
But the Dr. said when a person is resuscitated they do not return with a 'magical enhancement' of their memories. He told : 'They'll
describe watching doctors and nurses working, they'll describe having
awareness of full conversations, of visual things that were going on,
that would otherwise not be known to them.
'It
[the time a patient is declared dead] is all based on the moment when
the heart stops. Technically speaking, that's how you get the time of
death.'
Doctors pronounce the time of
death when the heart stops and when this happens, brain function halts
'almost instantly', the Dr. added.
But
he claims that he brain's cerebral cortex, known as the 'thinking
part', also slows down and flatlines, but the brain cells can still be
active hours after the heart stopped.
Performing CPR on someone whose heart has
stopped will send around 50 per cent of what blood it needs to the
brain, which the Dr. says is enough to kick-start its functions.
He
added: 'If you manage to restart the heart, which is what CPR attempts
to do, you'll gradually start to get the brain functioning again.
'The
longer you're doing CPR, those brain cell death pathways are still
happening — they're just happening at a slightly slower rate.
'What tends to happen is that people who've had these very profound experiences may come back positively transformed.
'They become more altruistic, more engaged with helping others.
'They
find a new meaning to life having had an encounter with death. But
there isn't like a sudden magical enhancement of their memories.'
His study is
examining what happens to the brain after a person goes into cardiac
arrest and whether consciousness continues after death and for how long.
The aim of the research is to improve the quality of resuscitation and prevent brain injuries while restarting the heart.
