The Mystery of Deathbed Visions Revealed

Scientists recorded brain activity after heart stoppage - similar to sleep or memories

The human brain at the moment of death may experience something resembling sleep or memory playback. This was reported by neurosurgeon Ajmal Zemmar from the University of Louisville, according to Metro.

The unique study was conducted by analyzing the electroencephalogram of an 87-year-old patient during the 30 seconds before and after cardiac arrest. According to the scientist, gamma oscillations were recorded during this critical period, which are traditionally associated with sleep and memory processes. Zemmar emphasized that the brain is capable of activating memories, including the most significant life moments, even at the moment of dying and for a short time after clinical death occurs.

These astonishing observations, according to the neurosurgeon, could radically change the scientific understanding of when exactly death occurs. Moreover, the discovery raises serious questions regarding the timing and ethical permissibility of organ harvesting for transplantation.

Also, researchers from McGill University previously established that disruption of circadian rhythms during adolescence can significantly affect brain development, especially in the presence of congenital risks - for example, if the mother had an infection during pregnancy.
