![]() ![]() Are these profound flashbacks real?Īccording to Zemmar, it's virtually impossible to tell. "This was actually totally by chance, we did not plan to do this experiment or record these signals," Zemmar told the BBC. ![]() This also makes it the first-ever recording of a dying human brain, albeit accidental. In other words, during the moments leading up to the man's death, his life effectively 'flashed' before his eyes, with other researchers involved in the study saying the brain activity resembled patterns observed during a state of dreaming, concentration, or meditation. "Through generating oscillations involved in memory retrieval, the brain may be playing a last recall of important life events just before we die, similar to the ones reported in near-death experiences." At the time of the discovery, he was a neurosurgeon at the University of Toronto, Canada. "Just before and after the heart stopped working, we saw changes in a specific band of neural oscillations," said senior researcher Ajmal Zemmar of the University of Louisville in Kentucky. What do you imagine death to be like? IMAGE: Cris Trung / Unsplash They found that in the 30 seconds before and after the man's heart stopped beating, the brain acted very unusually. What the researchers observed in the recording (900 seconds long) is rather fascinating, and could provide further insight into what happens when we die. However, the elderly man suddenly suffered a fatal heart attack while still in the MRI machine. It was supposed to be a routine scan in which the team used continuous electroencephalography (EEG) to detect seizures that commonly occur in epilepsy patients. They wound up accidentally recording what happens during the moment of a human brain's death. IMAGE: Frontiers In Ageing Neuroscienceīack in 2016, a team of researchers set out to scan the brainwaves of an 87-year-old man with epilepsy. However, in most cases, this would be deemed medically unethical – making a person spend the final moments of their life inside an MRI machine. After all, a person on the verge of death would literally have to get their brain scanned as they breathe their last breaths. Zemmar said he received interview requests from news outlets all over the world 48 hours after publishing in Frontiers in Aging Neuroscience on Tuesday.We've all heard the 'myth' about life literally flashing before your eyes when you encounter a near-death experience (NDE), or when a person does actually die.īut there's never been a way to actually support that theory. However, it has the ability to get people talking, which is what his study has done. It is impossible to go and find somebody to say are you going to come and let me do an experiment to record from your brain just before you die? You can’t plan this.” ![]() That would be just me as a scientist looking at this. ”From my perspective,” Zemmar said, “I would ideally like to have a healthy human being who is on the transition phase of death and I would record the signals of their brain to know what is going on. Similar results have been discovered in rat studies, but capturing that critical moment in a dying human brain remains nearly impossible. His research is based solely on the findings of one patient who died six years ago. So, when do people truly die? According to Zemmar, that answer may still be a long way off. “Is it enough to measure heart activity of patients in the ICU, or should we talk and discuss about the paradigm shift to say we need to measure brain activity as well? When are we really dead?” ”We have opened the door to discussing,” Zemmar said. It calls into question the medically accepted definition of death as the cessation of heartbeat. Zemmar was part of a Canadian team of doctors who recently published a study that challenges a slew of preconceived notions about our final moments on Earth. According to Zemmar, it implies that as people die, their last thoughts are a replay of events from their lives. ![]() Zemmar’s recording revealed that the patient’s brainwaves showed he was dreaming or recalling memories 30 seconds before and 30 seconds after his heart stopped. So what we knew before was these experiences people would tell us about near death, but nobody knew what the brain would do.” “This is the first time that we’re doing that. “Nobody ever recorded from a dying human brain,” UofL neurosurgeon Dr. Now, a University of Louisville researcher studying brain wave recordings of a dying patient has discovered scientific evidence that these experiences could be real. (WAVE) - People have long told stories about how a near-death experience can cause their life to flash before their eyes. ![]()
