Ondas Cerebrais surgem imediatamente após Morte!

Todos nós ja ouvimos falar de casos de pessoas que perto da morte assistiram a "entradas no tunel" ou a reviver toda a sua vida.... Agora, após alguns estudos ciêntistas chegararm á conclusão que após a morte, o cerebro emite ondas cerebrais... será isso a causa do "near-dead experiences"? aqui vai o artigo:

"A study of seven terminally ill patients found identical surges in brain activity moments before death, providing what may be physiological evidence of "out of body" experiences reported by people who survive near-death
Writing in the October issue of the Journal of Palliative Medicine, the doctors theorize that the brain surges may be tied to widely reported near-death experiences which typically involve spiritual or religious attributes.
At first, doctors thought the electrical surges picked up by electroencephalographs were caused by other machines or cell phones in the rooms of dying patients, lead author Lakhmir Chawla told Discovery News.
The EECs were being used to monitor patients' level of consciousness as doctors and families wrestle with end-of-life issues.
The doctors believe they are seeing the brain's neurons discharge as they lose oxygen from lack of blood pressure.
Brain researcher Kevin Nelson at the University of Kentucky, who studies near-death experiences, said it's well known that when the brain is abruptly deprived of blood flow it gives off a burst of high voltage energy.
