Does life really flash before our eyes when we die?

What happens when we die? Does life really flash before the eyes? Scientists say, "yes".
This experience has been narrated by many people who had a near death experience.
Scientists unintentionally recorded the brain activity of a man during the time of death.
They were monitoring the brain activity of an 87 year patient, who had developed epilepsy after a fall.
The patient, unfortunately, suffered a heart attack and died shortly after.
His tragic death allowed the scientists to record brain activity 30 seconds prior and after the heart stopped beating.
Dr. Ajmal Zemmar, a neurosurgeon at the University of Louisville, who led the study said:
“Just before and after the heart stopped working, we saw changes in a specific band of neural oscillations, so-called gamma oscillations, but also in others such as delta, theta, alpha and beta oscillations.”
Gamma brain waves are the fastest brain oscillations and mainly occur when you’re highly alert and conscious. They’re associated with higher-order cognitive functions, being particularly active when concentrating, dreaming, and meditating, as well as when the brain is engaged in memory retrieval, information processing, and conscious perception.
“These findings challenge our understanding of when exactly life ends and generate important subsequent questions, such as those related to the timing of organ donation,” Zemmar said.
“Something we may learn from this research is: although our loved ones have their eyes closed and are ready to leave us to rest, their brains may be replaying some of the nicest moments they experienced in their lives.”
