It is like a dream or deep meditation!
Scientists have studied the EEG of a dying brain for the first time in the world: it belonged to an 87-year-old patient with epilepsy.
Researchers from Canada, the US, China and Estonia studied how the dying brain behaves: the data was obtained by chance during the recording of a continuous electroencephalogram (EEG). During this, the patient suddenly had a heart attack, which led to death.
The result was a 15-minute recording, which recorded the activity of a dying brain. The authors focused on studying 30 seconds of this activity in two periods: when the heart continued to beat and had already stopped.
It is noted that during this period, the activity of the gamma rhythm was increased – these are brain waves that are activated during dreams or meditation. They suggested that at the time of death the patient recalled important events from his life.
By generating memory-seeking oscillations, the brain can recall last memories of important life events right before death. It could change our ideas about when life ends. – Ajmal Zemmar, lead author of the study
The authors note that so far there is not enough data to draw global conclusions about brain activity. However, scientists suggest that they have evidence of the ability of the brain to coordinate activity even after blood stops circulating through it.
Now scientists have a reason to study near-death and post-mortem experiences: before they did not become the object of serious scientific work.
