![]() ![]() “We measured 900 seconds of brain activity around the time of death and set a specific focus to investigate what happened in the 30 seconds before and after the heart stopped beating,” says study organizer Dr. OSDH: 1,300 new cases, 49 deaths from COVID-19 in Oklahoma This event was unexpected and tragic, but it did provide the research team with a unique opportunity to view brain activity in real-time as an individual passes away. Unfortunately, during an EEG recording session the patient suffered a heart attack and died. Raul Vicente of the University of Tartu and his team used electroencephalography (EEG) to detect the patient’s seizures and provide treatment. Researchers accomplished this by monitoring an 87-year-old epilepsy patient near the end of their life. This latest research supplies serious evidence that the brain remains both active and coordinated during and after the “death transition.” Interestingly, further data also suggests that this “life replay” is a programmed, biological response that comes naturally to human brains - and possibly many other species as well. 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. For example, waiting for the clock to reach 5 p.m. But what's memorable would be different for every person.‘Heartbreaking’: Girl Scout troop robbed while selling cookies in IowaĪlbert Einstein once said that time is relative, meaning the perceived rate by which time passes depends on the person and situation. Zemmar speculates that "if the brain did a flashback, it would probably like to remind you of good things, rather than the bad things. And findings like this - it's a moment that scientists live for," he shared.Īnd while it's impossible to tell what kind of moments or memories are specifically recalled during a person's final moments, Dr. "I think there's something mystical and spiritual about this whole near-death experience. Zemmar told BBC that the similarities between the rat studies and his findings are "astonishing." In 2013, researchers studied the brainwaves of healthy rats and discovered high levels of brain activity for up to 30 seconds after the rats' heartbeats stopped.ĭr. Zemmar and his team warn that conclusions should not be drawn from just one study, and that patient-related complications, such as epilepsy, need to be considered. In the case of the 87-year-old patient, for example, his heart stopped beating 30 seconds before his brain stopped functioning. While the new study explores the idea that our brains give us a final flashback, it also raises questions on "when, exactly, life ends." Zemmar said the brainwaves he observed might 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." Ajmal Zemmar, a neurosurgeon at the University of Louisville and co-author of the study published by Frontiers in Aging Neuroscience, told BBC.ĭr. We did not plan to do this experiment or record these signals," Dr. Scientists now believe this sort of brain activity might prove that a final "recall of life" occurs in a person's last moments. The unexpected event now serves as the first medical recording of a "dying brain."Īccording to BBC, the recorded research revealed that for 30 seconds prior to and 30 seconds following the man's death, the patient's brainwaves followed similar patterns to those that appear when we are dreaming or recalling memories. ![]()
