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. “Evolution was far more thrilling to me than the biblical account.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. “Life doesn’t happen in chapter – at least, not regular ones.” – explaining in a 2008 interview why Discworld books don’t have chapters
