![]() In a new paper published Monday in the Proceedings of the National Academy of Science (PNAS), researchers at the University of Michigan found evidence of surges in brain activity associated with consciousness in two dying patients. The fact that these stories share so many elements in common and come from people from diverse cultural backgrounds points to a possible biological mechanism - one that has yet to be de-mystified by scientists. ![]() WASHINGTON - Survivors of close calls with death often recall extraordinary experiences: seeing light at the end of a tunnel, floating outside their own bodies, encountering deceased loved ones or recapping major life events in an instant. “And findings like this – it’s a moment that scientists lives for.Operating room at Queen Fabiola Children's University Hospital in Brussel, Belgium. I think there’s something mystical and spiritual about this whole near-death experience,” Dr. They now hope the publication of this one human case may open the door to other studies on the final moments of life. The similarities between studies are “astonishing”, Dr. In that analysis, US researchers reported high levels of brainwaves at the point of the death until 30 seconds after the rats’ hearts stopped beating – just like the findings found in Dr. And for years after the initial recording in 2016, he looked for similar cases to help strengthen the analysis but was unsuccessful.īut a 2013 study – carried out on healthy rats – may offer a clue. I never felt comfortable to report one case,” Dr Zemmar said. The fact that the patient was epileptic, with a bleeding and swollen brain, complicates things further. The study also raises questions about when, exactly, life ends – when the heart stops beating, or the brain stops functioning.ĭr Zemmar and his team have cautioned that broad conclusions can’t be drawn from a study of one. This could possibly be a last recall of memories that we’ve experienced in life, and they replay through our brain in the last seconds before we die.” It continued 30 seconds after the patient’s heart stopped beating – the point at which a patient is typically declared dead. Zemmar, now a neurosurgeon at the University of Louisville, said in the 30 seconds before the patient’s heart stopped supplying blood to the brain, his brainwaves followed the same patterns as when we carry out high-cognitive demanding tasks, like concentrating, dreaming or recalling memories.

Dr. He told the BBC: “This was actually totally by chance, we did not plan to do this experiment or record these signals.” Ajmal Zemmar, a co-author of the study, said that what the team, then based in Vancouver, Canada, accidentally got, was the first-ever recording of a dying brain. It revealed that in the 30 seconds before and after, the man’s brainwaves followed the same patterns as dreaming or recalling memories.īrain activity of this sort could suggest that a final “recall of life” may occur in a person’s last moments, the team wrote in their study, published in Frontiers in Aging Neuroscience on Tuesday.ĭr. But during the neurological recording, he suffered a fatal heart attack – offering an unexpected recording of a dying brain. New data from a scientific “accident” has suggested that life may actually flash before our eyes as we die.Ī team of scientists set out to measure the brainwaves of an 87-year-old patient who had developed epilepsy.
