Scientists Confirm Brain’s ‘Life-Flash’ Surge Just Before Death
Evidence from a recent scientific investigation suggests that a commonly accepted phenomena most likely occurs just before death.
People who have had near-death experiences—in which their bodies technically die but are revived by medical professionals—have described a variety of strange and amazing experiences, including devils singing Rihanna in hell and feeling as though they are leaving their bodies behind and ascending to heaven.
However, obtaining trustworthy data regarding what happens after death is extremely difficult. After all, keeping a dying person hooked up to machines and left there until their last breath isn’t exactly humane.
A well-known notion about what humans go through in our last moments was validated by one of the best discoveries we have ever made concerning what happens when the body dies.
The most popular theory about what happens when we die
The ‘life flashing before your eyes’ phenomenon is certainly familiar to you, and it usually occurs prior to your death.
In essence, it is thought that just before you die, your entire life—or at least the significant portions of it—repeats itself in your mind.
Philosophers like Plato first discussed the idea millennia ago when they related tales of warriors who had out-of-body experiences after “returning from death.”
The cliché of life flashing before one’s eyes appears in many popular culture works, including songs, poems, and movies.
For a long time, it was only a theory in the medical field, but a few years ago, we received some hard proof that it is true.
Scientists find evidence about what happens to the brain during death
Finally, some answers were promised by a study that was published in February 2022 in the Frontiers in Ageing Neuroscience magazine.
An 87-year-old patient with epilepsy was undergoing electroencephalography (EEG) scans to look for seizures, conducted by a multinational team of 13 neuroscientists under the direction of Raul Vicente of the University of Tartu in Estonia.
Sadly, the man died unexpectedly as the EEG scan was being performed.
The patient’s identity was kept confidential, and despite having a heart attack in front of medical professionals, his do-not-resuscitate status allowed for the tracking of his brain waves in the 30 seconds before to and following his heart stopping.
The EEG brain scan revealed an oscillatory brain wave pattern, with an increase in gamma waves suggesting a possible memory recall and a decrease in the brain’s alpha, beta, and theta bands.
Dreaming and meditation can both produce these same patterns.
What did the researchers say about their findings?
“This is why it’s so rare, because you can’t plan this,” Ajmal Zemmar, one of the study’s co-authors, told Insider.
“No healthy human is gonna go and have an EEG before they die, and in no sick patient are we going to know when they’re gonna die to record these signals.”
Numerous persons who have described near-death experiences, hallucinations, or seeing their lives flash before their eyes appeared to have their claims supported by the researchers’ findings.
Zemmar said, “It is very hard to make claims with one case, especially when the case has bleeding, seizures, and swelling.”
“But what we can claim is that we have signals just before death and just after the heart stops like those that happen in the healthy human when they dream or memorise or meditate.”
What other evidence is there about what happens when we die?
A study conducted in March 2019 looked more closely at accounts of near-death experiences (NDEs).
It discovered that reports of near-death experiences ‘are comparable among persons of diverse cultures, suggesting an underlying neurological basis’ and attempted to determine whether or not people who took different medicines had similar experiences.
Results showed that the hallucinogenic DMT and ketamine users spoke similarly to individuals who had experienced NDEs.
Previous research has examined the religious relevance of near-death experiences (NDEs), concentrating on survivors’ descriptions of their pre-death spiritual states.
However, there is still no explanation for why the brain experiences a brief period of activity prior to death, even with the most recent discoveries.
We can view it as life’s last gift to us, leaving us with something joyful and upbeat, but hopefully we will soon be able to understand the phenomenon.
