One way to do so might be to create an experiment that simulates a near-death experience while the patient is being monitored under lab conditions. These were to devise a questionnaire which was sent out to 264 other people who gave detailed responses of their experiences. What’s more, it’s not possible to confirm that the patients really had any visions as they did not live to tell the tale.īorjigin hopes in the future to collect data on hundreds more people – increasing the chances that some will actually survive.
Owing to the small sample size, the authors cautioned against making wide-ranging inferences. It’s not clear why two of the patients experienced these potential signs of “covert consciousness” while two did not, though Borjigin speculated their history of seizures might have primed their brains in some way. “If this part of the brain lights up, that means the patient is seeing something, can hear something, and they might feel sensations out of the body,” said Borjigin, adding that the region was “on fire.”īrain and heart activity were monitored, second by second, for the last few hours of the patients’ life, contributing to the strength of the analysis, she added. The University of Michigan paper went further by examining in greater depth which parts of the brain lit up, with the activity detected in the “posterior cortical hot zone” – comprised of the temporal, parietal and occipital lobes, which are associated with changes in consciousness. When taken off their ventilators, two of the four patients – a 24-year-old woman and a 77-year-old woman – saw increases in their heart rates as well as surges of brain waves in the gamma frequency – the fastest such brain activity, which is associated with consciousness.Įarlier studies – including a prominent paper published in 2022 about an 87-year-old man who died from a fall – have also found spikes in gamma waves in some people near the point of death. The team looked back at the records of four patients who died from cardiac arrest while on electroencephalogram (EEG) monitoring.Īll four fell into comas and were removed from life support after it was determined they were beyond medical help. While not the first study of its kind, what sets the new research apart is that it’s detailed in a way “that’s never been done before,” senior author Jimo Borjigin, whose lab is devoted to understanding the neurological basis of consciousness, told AFP. In a new paper published 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 demystified by scientists.
Zemmar's name was spelled incorrectly in an earlier version of this article.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. "If I can contribute to tell them that your loved one in this moment doesn't have pain, they're fine, they're experiencing the most memorable moments of your life before they go, I think that would mean a lot and comfort my patients."ĬORRECTION (March 12, 2022, 1:50 p.m.): Dr. "These families have an unimaginable amount of pain in these moments. Science Confirms That Life Flashes Before the Eyes Upon Death It’s been an age-old trope in literature and film but now brain scans suggest it’s true. Zemmar hopes this case could bring comfort to grieving families after losing a loved one. Since this was only one case, more research is needed to determine if this phenomenon is something all of us experience or not.īut Dr. When your life flashes before your eyes, in other words, it isn’t the brain reacting to the threat of death in some special, mystical way it’s just a super-concentrated version of mental processes that happen every day. That’s how they realized just how rare it was to capture this type of brain recording.
Zemmar said the study was done in 2016, and they waited years to publish their work, reaching out to colleagues with the hope of finding more case studies. If you have many eye floaters and flashes, it could be a sign of a serious eye condition like retinal detachment. Floaters are very common and typically don’t require treatment. His work is now published in the journal "Frontiers in Aging Neuroscience."ĭr. Floaters appear in your field of vision as small shapes, while flashes can look like lightning or camera flashes. "I would like to think that it is a soothing feeling just before we die, and we experience the most memorable experiences of our life flashing in the span of seconds through our head just before we go," he said.
