[Instant News/Comprehensive Report]When people are on the verge of death, there is often a saying that the so-called “marquee of life” emerges. Recently, scientists recorded the brain activity of an experimenter on the eve of death for the first time, and found that there were related dreams and memories. Waiting for the activity of brain waves may explain the “marquee of life”.
Technology media “New Atlas” reported on the 21stscientists have recorded activity in the brains of dying humans for the first time ever, not specifically to measure brain activity before and after death, but during an accidental burst when researchers used the brain Electrogram (EEG) monitoring of the brain waves of an 87-year-old epilepsy patient to observe seizures, unexpectedly, the patient died of a sudden heart attack during the monitoring process.
The researchers managed to record brain activity for 15 minutes before and after death. They focused their attention on the 30 seconds when the heart stopped beating and found increased activity of the type of brain waves that detected Gamma waves, a property of gamma that includes the processes of dreaming, meditation and memory retrieval. , giving a glimpse of what a person might be going through at the last moment.
Dr Ajmal Zemmar, lead author of the study, said: “By generating oscillations in memory retrieval, the brain may have a final recall of important life events before we die, similar to those reported in near-death experiences.”
However, Zemar also emphasized that the study should be viewed with caution because the data are from only 1 case study, even in a patient with a brain injury and abnormal epilepsy-related activity, the researchers hope in other situations. Further investigation below.
Zemar noted that the study provides an opportunity to learn that “even though our loved ones have their eyes closed and ready to rest, their brains may be replaying some of the best moments of their lives.”
