![]() ![]() 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 on a Friday can feel like an eternity, but the weekend usually ends in the blink of an eye.Ĭould our brains really “replay” an entire lifetime’s worth of memories and moments within a matter of seconds upon death? Countless people who have had near-death experiences testify as much, but up until now neuroscientists have struggled to make sense of what happens in the mind during and immediately after death.Account icon An icon in the shape of a person's head and shoulders. For example, waiting for the clock to reach 5 p.m. Recorded brain gamma waves during death were similar to those that occur during dreaming and meditation.Īlbert Einstein once said that time is relative, meaning the perceived rate by which time passes depends on the person and situation. The data, at the very least, suggests that our brains indeed continue working not only as we pass away but even in the seconds following heart stoppage. Now, groundbreaking new research by a team at the University of Tartu is providing the first ever record of brain activity during death. TARTU, Estonia ( ) - The notion of “your life flashing before your eyes” as you die has been a cultural expression for over a century, depicted in countless movies, books, and other works of fiction.
