Recording the brain waves of the dead for the first time, revealing the terrible truth

Recently, neuroscientists in the US accidentally recorded the "activity" of a dying brain while they were using electroencephalography (EEG) to detect and treat epilepsy. menstruation in an unnamed 87-year-old man.

There is an increase in brain waves known as gamma oscillations during memory recall.

Reportedly, because the patient unexpectedly had a heart attack and died during the study while still connected to the EEG machine, the researchers had a unique opportunity to record about 15 minutes of activity. of the brain after the heart stops beating. This is the first study to successfully measure brain activity after a person has died.

From this record, they discovered that there was an increase in brain waves known as gamma oscillations, which normally occur during dreaming and memory recall. As such, a dying person can actually get what we call a "glimpse" of their life flashing before their eyes.

This concept can be quite terrifying to some people, even if you think about it for a moment, but to scientists, they consider it an extremely interesting mystery.

"Through the generation of oscillations involved in memory retrieval, the brain may be recalling important life events just before we die, similar to those reported in our experience. near-death experience," said study author Dr Ajmal Zemmar from the University of Louisville.

Not only does this provide an insight into the mysterious, yet terrifying moment we all end up experiencing, but it also has many other uses, such as "the moment to donate organs." ideal", Dr. Zemmar added. "These findings challenge our understanding of exactly when life ended."

According to DailyMail, some previous studies on the brain activity of dying rats also showed similar gamma activity. This may suggest that this is a natural occurrence of species, not just humans. However, scientists are still unable to draw a definitive conclusion in this case, because the unnamed man was in a state of traumatic brain injury and seizures.
