The Brain Is Active Before Death

Scientists have made an important discovery while studying patients' brain activity in the final moments of life. Electroencephalogram (EEG) studies revealed a sudden surge in electrical activity just before death, which may explain the phenomenon of near-death experiences (NDEs) reported by people "returning from the dead."

Experts suggest that this surge in activity is related to the brain's response to oxygen deprivation. When blood flow slows, brain cells attempt to compensate by creating a powerful electrical impulse that spreads throughout the neural network. This, according to scientists, may be what causes sensations of bright light or floating above one's body.

NDEs have long been considered mystical or religious visions. People have described them as feelings of leaving their bodies, meeting loved ones, or seeing a tunnel with a bright light. New research allows us to consider these sensations from a physiological perspective, not just spiritual interpretations.

During the study, a team led by intensive care physician Lakhmir Chawla observed seven patients. Despite the small sample size, the results were consistent with previously reported cases. Chawla notes that he has personally observed similar surges of activity in patients over fifty times, confirming the repeatability of the phenomenon.

Experts emphasize that the electrical impulse is not a random phenomenon. It occurs in a cascade, beginning in one area of ​​the brain and spreading throughout the nervous system, which explains the intensity and vividness of the experience. For patients, this can feel like an extremely realistic and emotionally charged experience.

The study opens new avenues for understanding brain processes at the threshold of life and death. It also helps doctors and families better understand the emotional and psychological aspects of dying patients, demonstrating that the brain remains active until the final moments.
