The expression “my life flashed before my eyes” is frequently used by those who have survived near-death experiences, and a recent study suggests that this may not simply be a figure of speech. For the first time in history, researchers were able to capture a brain’s activity during death. Additionally, it displayed brain wave patterns resembling those of dreaming and remembering things. Experts disagree as to whether this indicates that a person’s life truly does “flash before their eyes” just before they die.
What Takes Place When Someone Dies?
The study’s original goal did not include recording brain activity during a death. It was merely an accident. Researchers used electroencephalography (EEG) to track the brain waves of an 87-year-old patient in 2016. The guy was having convulsions when he suddenly suffered a heart attack and passed away. The scientists were able to observe his heart stopping and 15 minutes of brain activity. Three days earlier, the man had arrived at the Canadian hospital with bleeding between his skull and brain. After the clot was removed by Zemmar and the other medical professionals, the man started having seizures again.
Researchers observed slower brain waves, such as theta, delta, alpha, and beta, and elevated gamma oscillations in the thirty seconds prior to and following the time of death. This is the brain activity associated with dreaming, meditating, and retrieving memories. People may experience this mental state right before they pass away.
Lead study author Dr. Ajmal Zemmar said, “The brain may be playing a last recall of significant life events just before we die, similar to the ones reported in near-death experiences, through generating oscillations involved in memory retrieval.” “These results cast doubt on our comprehension of the precise moment of death and raise significant follow-up queries, such as those concerning the timing of organ donation.”
The recording demonstrated that even in the absence of blood supply, the brain is capable of coordinating synchronized actions. This is the first study to show this brain activity in people; similar increases in gamma oscillations have been documented in dying rats. This phenomenon was only seen in one case study. In addition, the patient’s brain experienced prior trauma and abnormal activity as a result of seizures.
“Reliving some of their most enjoyable times“
“Making claims with a single case is very difficult, particularly when there is bleeding, seizures, and swelling involved,” Zemmar stated. “However, we can assert that we possess signals that occur shortly before death and shortly after a heart-stopping, similar to those that occur in a healthy individual during dreams, memorization, or meditation.”
Before drawing any conclusions on what the brain does during death, researchers need to look at the brains of healthy cases. This might not be feasible, though, since they’ll require the participants to be connected to the EEG before death, and the majority of healthy individuals don’t plan on dying quickly. Therefore, there’s a greater chance that future participants will only have diseased conditions, which could make it more difficult for researchers to get conclusive information regarding brain activity just before death.
Whether these are final answers, this case study can offer some encouraging insights. As a neurosurgeon, I occasionally have to deal with loss. Giving grieving family members the news of a loss is unbelievably difficult, Zemmar added. “This research may teach us that even though our loved ones are going to sleep and have closed their eyes, their brains might be reliving some of the best times in their lives.”
“My life appeared in front of my eyes”
Thus far, the anecdotal claims of life evaluations during near-death experiences have been supported by this study. “The brain may still trigger those responses so that these patients perceive that near-death experience with the replay and everything,” according to Zemmar’s theory, in these particular situations.
According to one theory explaining the life review phenomenon, life events are stored in people’s minds as a continuum that intensifies during periods of high psychological and physical stress. According to a different theory, people’s memories start to “unload” as their bodies near death. But in a couple of seconds or fewer, so many memories could materialize in people’s minds that neither theory can account for.
This case study makes it possible to conduct more research on the topic. Zemmar remarked, “I think this whole near-death experience is mystical and spiritual.” “And discoveries such as these are what scientists live for.”
