![]() “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.” Colm Gorey, “ What Happens in Our Brain When We Die?” at Neuroscience News (February 22, 2022) “Through generating oscillations involved in memory retrieval, 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,” Zemmar speculated. The different types of oscillations, including gamma, are involved in high-cognitive functions, such as concentrating, dreaming, meditation, memory retrieval, information processing, and conscious perception, just like those associated with memory flashbacks. ![]() We can’t know what the patient was thinking, of course, but the pattern of brain waves was complex:īrain oscillations (more commonly known as ‘brain waves’) are patterns of rhythmic brain activity normally present in living human brains. “Just before and after the heart stopped working, we saw changes in a specific band of neural oscillations, so-called gamma oscillations, but also in others such as delta, theta, alpha and beta oscillations.” Colm Gorey, “ What Happens in Our Brain When We Die?” at Neuroscience News (February 22, 2022) “We measured 900 seconds of brain activity around the time of death and set a specific focus to investigate what happened in the 30 seconds before and after the heart stopped beating,” said Dr Ajmal Zemmar, a neurosurgeon at the University of Louisville, US, who organised the study. EEG Electroencephalogram, brain wave in awake state with mental activity.
