Doctors have found scientific evidence that the brains of people cancontinue to work once they are clinically dead. One patient showed brain activity persistent during ten minutes later his heart stopped andexperienced brain waves that normally receives during deep sleep.
A Canadian intensive care unit doctors described the case as extraordinary and inexplicable. Researchers from the University of WesternOntario in Canada assessed electrical impulses in the brain in connection with the beating of the heart of someone after vital therapy wasremoved. Brain inactivity preceded the heart stop at three of the fourcases. However, in one of the cases, the patient's brain continued to work after his heart. ' In ' one patient, only the delta wave gusts persisted after the cessation of the heart rate and blood pressure (ABP), the researchers said. There were no significant differences in the electrical activity of the brain between the 30-minute period and the periodof 5 minutes after detainee heart. "It is difficult to consider a physiological basis for this activity in EEG [brain] given that occurs after a prolonged loss of circulation," according to the newspaper that was published in the National Center of Biotechnology Information.Across thefour recordings of his brain patients were very different - suggestingall experience death in unique ways. The experiment raises difficult questions about when someone is dead, and therefore, when is medical and ethically correct to use for organ donation. As one-fifth of people who survive cardiorespiratory report having had an experience ofanother world being dead 'clinical'. However, scientists say it is too early to talk about what this could mean for the experience of death -bearing in mind that only observed in a patient, according to the Science Alert.In 2013, that a similar phenomenon was investigated in experiments on rats whose hearts had stopped. The research, which waspublished in the journal Proceedings of the National Academy of Sciences revealed the rats had a burst of brain activity one minute afterthe beheading.
The activity pattern was similar to that seen when the animals were fully aware - except the signs were up to eight times stronger. The researchers said that the discovery that the brain is very active in the seconds after the heart stops suggests that the phenomenon has a more physical than spiritual character.
It has been argued that brain death is incapable of activity as complex and as near-death experiences must have their origins in the soul. It suggests that something happens at the edge of death that encourages a high level of excitement, the conscious brain potentially trigger visions and sensations associated with near-death (NDEs) experiences. As one-fifth of people who survive cardiorespiratory report having had an experience of another world being dead 'clinical'. NDEs typically involve travel through a tunnel towards a strong light, being separated from the body, an encounter with beings dear deceased longor Angels and subjected to some kind of judgment of ' revision of life. Some come from NDEs as individuals transformed with a completely altered Outlook on life or a new belief in religion. But many scientists believe near death experiences are merely hallucinations inducedby the effect of the brain off.
WHAT MADE?
Canadian doctors studied brain activity and the heartbeat of four patients in intensive care after you have switched off their machines. Brain inactivity preceded the heart stop at three of the four cases. However, in one of the cases, only delta wave explosions persisted after theheart had stopped, and the patient was clinically dead. We usually have these brain waves into a deep sleep.
