This has been known from time immemorial, but only now scientists have found an explanation for this inexplicable phenomenon.
First of all, the researchers were able to reliably record that when people transition from a living state to an inanimate state, the heart rate increases, and the brain increases its activity.
Scientists believe that before death, people really see their whole life
Those who survived clinical death talk about an unusual condition. Some say that they “floated over their own body”, others talk about “a long tunnel with light at the end”, others report meetings with deceased relatives.
Many claim to have seen a kaleidoscope of scenes from their lives. Scientists have come to the conclusion that the phrase “all life flashes before our eyes” is based not on people’s fantasies, but on a real biological mechanism. Its nature has yet to be determined.
A group of scientists from the University of Michigan found unusually large bursts of brain activity in dying patients. At the same time, the nature of the activity indicated that people see something in the last moments.
Bursts were recorded in areas associated with consciousness. In particular, abnormal activity was recorded at the gamma frequency, which is the fastest in the human brain. By studying these bursts in more detail, they found that gamma-wave activity begins in the back of the brain.
Thus, despite physical immobility, people can see pictures and images in their minds. Scientists believe that this does not happen to everyone and depends on some individual characteristics that can activate brain activity.
Scientists themselves urge to treat their findings with caution. They indicate a small sample size. The researchers plan to conduct a similar experiment in a lab with a volunteer who agreed to simulate a near-death experience.
The study has been published in PNAS.
