Deja vu: Speculation & science behind the experience.

Scientists revive cells and organs in dead pigs.

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. 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 Monday 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 de-mystified by scientists. WASHINGTON - 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.
