![]() ![]() On the contrary, someone who has a protracted history of a serious illness might be more likely to get a rough ride. ![]() Some people, having undergone anaesthesia while in good shape or having been involved in a sudden accident leading to instant loss of consciousness have little ground to experience deep anxiety as their brain commences to shut down. One key limitation of studies looking into such experiences is that they focus too much of the nature of the experiences themselves and often overlook the context preceding them. Such an event has been associated with out-of-body experiences, a sense profound bliss, a calling, a seeing of a light shining above, but also profound bursts of anxiety or complete emptiness and silence. Could there be anything of my beloved brother’s mind left to hear my voice and generate thoughts, five hours after he had passed away? Some scientific experimentsĮxperiments have been conducted in an attempt to better understand reports from people who have had a near-death experience. Then, deterioration reaches a point of no return and core consciousness - our ability to feel that we are here and now, and to recognise that thoughts we have are own own - is lost. What can brain waves really tell us? ShutterstockĪnd I did, despite 25 years of studying the human brain and knowing perfectly well that about six minutes after the heart stops, and the blood supply to the brain is interrupted, the brain essentially dies. ![]() Yet, in the last moment I was given to spend with his lifeless body in a hospital room, I felt the urge to speak to him. No matter how much I refused to believe it on that day, and during the several months that followed, my brother’s extraordinarily bright and creative mind had gone, vapourised, only to remain palpable in the artworks he left behind. Only he was not breathing anymore and he was cold to the touch. An hour later, I found him perfectly still and beautiful, his head slightly turned to the side as if he was in a deep state of sleep. But when I landed, I was told my brother had passed away four hours ago. I set off to Marseille, France, having been summoned to Avignon by my mother because my brother was in a critical state, a few days after being suddenly diagnosed with terminal lung cancer. On June 14, 2021, I was violently reminded of these questions. Words I remember to this day were the last of Georges Danton on April 5, 1794, who allegedly said to his executioner: “Show my head to the people, it is worth seeing.” Years later, having become a cognitive neuroscientist, I started wondering to what extent a brain suddenly separated from the body could still perceive its environment and perhaps think.ĭanton wanted his head to be shown, but could he see or hear the people? Was he conscious, even for a brief moment? How did his brain shut down? I had just discovered gruesome aspects of the French revolution and how heads were neatly cut off the body by a Guillotine. The bottom line: Zemmar said the research showed that “the brain may be playing a last recall of important life events just before we die, similar to the ones reported in near-death experiences.The first time I reached past the sheer horror of the concept of death and wondered what the experience of dying may be like, I was about 15.
