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. However, it could pave the way for further research and a deeper understanding of what goes through our minds in our last moments.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. The researchers cautioned that the study was the first of its kind and involved a brain that had already been injured due to epilepsy. "Something we may learn from this research is that, although our loved ones have their eyes closed and are ready to leave us to rest, their brains may be replaying some of the nicest moments they experienced in their lives." "It is indescribably difficult to deliver the news of death to distraught family members. He added: "As a neurosurgeon, I deal with loss at times. It raises the question of whether our lives really do "flash before our eyes" in our final moments.ĭr Ajmal Zemmar, a neurosurgeon at the University of Louisville, who led the study, told ZME Science: "These findings challenge our understanding of when exactly life ends and generate important subsequent questions, such as those related to the timing of organ donation."

The recorded brain waves - known as gamma oscillations - suggest that, as we die, we experience the same neural activity as during dreaming, recalling memories, or meditating.īlood thinners do not reduce miscarriage risk, study suggests These brain waves - gamma waves - are associated with more sophisticated cognitive functions and are especially active when we are concentrating, dreaming and meditating, as well as retrieving memories and processing information. Scientists saw that, in the 30 seconds either side of the man's final heartbeat, there was an increase in a certain type of brain wave. The man was hooked up to an electroencephalogram, which records brain activity, when he had a sudden heart attack and died.īut the electroencephalogram continued recording his brain activity, including during the 15 minutes around his death.
Scientists have accidentally recorded the most complex human organ as it shuts down - providing an insight into what might happen in the moments before we die.Ī study, published in Frontiers In Aging Neuroscience, focused on an 87-year-old man being treated for epilepsy.
