Sam Parnia, an associate professor at NYU Langone Health and author of 'What Happens When We Die?,' told Insider other studies have shown that when people start to die, 'they have paradoxical lucidity with heightened consciousness. Previous studies found signs of 'heightened consciousness' at the end of lifeĭr. When someone almost dies, Zemmar said, 'the brain may still trigger those responses so that these patients perceive that near-death experience with the replay and everything, but then come back.' The findings square with some anecdotal reports of near-death experiences, in which people say life's most intensely emotional moments replay before their eyes. 'It is very hard to make claims with one case, especially when the case has bleeding, seizures, and swelling,' Zemmar said, or other complications that could account for the findings. 'But what we can claim is that we have signals just before death and just after the heart stops like those that happen in the healthy human when they dream or memorize or meditate.' They only found one similar study on rats in which scientists induced cardiac arrest in the animals while measuring their brain activity. It took his team of colleagues from around the world five and a half years to publish the study in part because they were waiting to see if any other similar cases cropped up. These patterns are associated with concentration, dreaming, meditating, memory retrieval, and flashbacks, ZME Science reported. The EEG showed that, 15 seconds before the patient's heart stopped beating, he experienced high-frequency brainwaves called gamma oscillations, as well as some slower oscillations including theta, delta, alpha, and beta. No healthy human is gonna go and have an EEG before they die, and in no sick patient are we going to know when they're gonna die to record these signals,' Zemmar said. 'This is why it's so rare, because you can't plan this. But before they could determine the appropriate treatment, the man went into cardiac arrest and died.

The doctors, including Zemmar, removed the clot, but three days later, the man developed seizures.Īs is standard, Zemmar said, the medical team monitored the patient with an electroencephalogram, or EEG, to determine the root of the seizures. The paper traces back to 2016, when an 87-year-old man with bleeding between his skull and brain sought treatment at a Canadian hospital. Researchers captured the dying man's brain activity by rare chance Account icon An icon in the shape of a person's head and shoulders.
