Human brain may stay active for hours after death
Well, THAT depends on how active it was BEFORE death, but I degress...........
One question that has baffled mankind is “after-death experience” or the experience after the heart stops beating. There have been anecdotal reports of a person being able to understand and hear what is happening around them even after they have been declared dead. A team of researchers have found that the brain works for a while after the heart has stopped. The research is reported in an a journal paper titled, 'AWARE—AWAreness during REsuscitation—A prospective study.'
The team of scientists from New York’s Stony Brook University of Medicine, looked at patients with cardiac arrests in Europe and the US. They noted that those of the patients who were successfully resuscitated after their heart had stopped beating could recall the conversations around them between the healthcare personnel and were aware of their surroundings.
(A question arises, if true, does that mean you have several hours of agony before checking out completely? I hate to think of that possibility)
Study leader Dr. Sam Parnia said that the patients could describe in details what happened around them. He explained that the time death is declared is the one when the heart stops beating. As the heart stops beating, it stops pumping blood to the brain and slowly the brain begins to shut down, he explains. He added that this process of the brain shutting down slowly may take hours and the person may be dead during this time but aware of their surroundings.
What this study means is that people are trapped inside their dead bodies for a while after they are declared dead.
