People who have experienced near death situations claim they had flashbacks of their entire life. However, these were only speculations. No expert yet made a clear explanation if this really happens, and why does it happen. Thus, researchers from Hadassah University in Jerusalem studied this phenomenon.
Experts identified the surge of memories during a near death experience as “life review experience” (LRE). They have suggested that it truly occurs, and the flashback of memories of the dying person may be seen in a chronological order.

The researchers suggest, the reason behind it is because certain parts of the brain that stores memories are the last to shut down when the body is close to death.
For the study, researchers interviewed 200 people who have experienced LRE. They then analyzed seven of these responses in depth.
Based on The Telegraph
, one participant involved in the study wrote, “There is not a linear progression, there is lack of time limits... It was like being there for centuries. I was not in time/space so this question also feels impossible to answer.
“A moment, and a thousand years... both and neither. It all happened at once, or some experiences within my near death experience were going on at the same time as others, though my human mind separates them into different events.”
The probable explanation is that, parts of the brain that store memories, such as the prefrontal, medial temporal and parietal cortices, will continue to function for longer than other parts of the brain after serious injury, experts say.
Therefore, the researchers concluded that these parts of the brain could be responsible for LRE, as well as other characteristics of near death experiences.
Experts added, “psychological and physiological stress” may be behind the mystifying experiences during LRE.
“Re-experiencing one’s own life events, so-called LRE, is a phenomenon with well-defined characteristics, and its subcomponents may be also evident in healthy people,” the authors wrote.
“This suggests that a representation of life events as a continuum exists in the cognitive system, and maybe further expressed in extreme conditions of psychological and physiological stress.”
