A medical study trying to find out what a person sees while dying

A new scientific experiment answers a question that has long baffled people, about the things that appear before their eyes in the moments of death.

What does a person see while dying? Scientists were able to come close to answering that question, after they monitored the brain activities of an 87-year-old dying after his heart stopped working, and his brain activity indicated that he recalled "old memories."

The results of that experiment were published in the scientific journal Frontiers in Aging Neuroscience, and the scientists explained that they put the patient on an EEG machine before his health deteriorated, which enabled them to monitor his brain waves while he was dying.

The scientists focused on the first 30 seconds before and after his heart stopped working, and they noticed changes in brain waves associated with memory retrieval, cognition and the different stages of life.

"People talk about episodes of elevated consciousness during dying and the onset of death, and it happens in the brain after it stops working and the person is dead," explains Dr. Sam Parnia of New York University.

This experience indicates that the expression “the age bar passes” before a person at the end of his life is scientifically accurate.
