(ORDO NEWS) — An international team of researchers scanned the brain activity of a dying person for the first time. Scientists have come to the conclusion that he sees pictures of a past life even after cardiac arrest.
The neurophysiological trace of brain activity after our heart stops beating is rather poorly understood. In general, we know little about the process of dying of the human brain.
True, animal experiments show that after cardiac arrest and until the moment when cerebral blood flow stops as a result of hypercapnia, increased activity is observed in the gray matter. But such studies have not been conducted for humans.
A team of scientists from the Medical School of the Universities of Henan (China), Tartu (Estonia), British Columbia and Toronto (Canada), Louisville and New York (USA) presented for the first time in history a continuous 15-minute electroencephalography (EEG) recording of a dying human brain – 87 -year-old man with epilepsy, whose heart stopped after a bad fall.
They focused on several areas of the EEG: before and after cardiac arrest. Those show that almost all brain activity after the heart stopped beating fell, but there was a surge in the gamma rhythm.
This state is similar to what we experience during dreams, or deep meditation. Therefore, scientists have suggested that before his death, the man saw visual images that could contain memories of a past life.
It is about such people, as you know, that people on their deathbed often report. According to experts, the findings show that our brain is capable of coordinated activity even after the blood supply to it stops.
Of course, it is too early to draw final conclusions, because only one person took part in the study, who, moreover, because of an illness, took a number of specific drugs during his lifetime, and died from a head injury.
Nevertheless, the work can be a good start in order to pay close attention to the study of near-death and post-mortem states of the human brain.
