SCIENTISTS RECORDED THE BRAIN ACTIVITY OF A PERSON AS THEY DIED, AND THE RESULTS ARE ASTONISHING
HE DIED WHILE HE WAS HOOKED UP TO A BRAIN MONITOR —
AND WHAT SCIENTISTS SAW IS A FASCINATING GLIMPSE OF THE END.

It turns out your life might actually flash before your eyes when
you die — or at least that’s what some researchers are suggesting in a new
first-of-a-kind paper that revealed the brain activity of a dying person.
The scientists were initially studying the brain waves of an
87-year-old epilepsy patient for seizures using an electroencephalography (EEG)
device, according to the team’s paper published in Frontiers in Aging Neuroscience.
However, the patient had a heart attack and died during the study,
while still hooked up to the EEG. This gave the researchers a unique
opportunity to record 15 minutes of brain activity of a dying person.
The researchers found that there was an increase in brain
waves known as gamma oscillations, which typically occurs during dreaming and
memory retrieval. So a person who is dying, they suggested, might
experience glimpses of their life flashing before their eyes.
“Through generating
oscillations involved in memory retrieval, the brain may be playing a last
recall of important life events just before we die, similar to the ones
reported in near-death experiences,” said the University of Louisville’s Dr.
Ajmal Zemmar, the lead author of the study, in a press release.
This not only gives insight into an enigmatic and frightening
moment that all of us will experience eventually, but could even offer better
understanding of the “timing of organ donation,” Zemmar added.
“These findings challenge our understanding of when exactly life
ends,” the doctor said.
Of course, there are some big caveats. For one, the paper only
looked at a single case. The patient also had a history of seizures and brain
swelling, which could impact the findings.
However, past research into the brain activity of dying rats also
showed similar gamma activity. That could suggest that this is a natural
occurrence across numerous species.
Zemmar added that while more research is needed, the insights
gathered from the patient can actually offer a bit of hope and closure to
families who are dealing with the death of a loved one.
“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,”
Zemmar said.
"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”... Or perhaps the nicest moments they anticipate experiencing, maybe? That was the implication of a remarkable scene in the hospital drama I watched with my wife last night, in which a dying mine imagines dancing with his daughter at her wedding (scheduled for 3 months hence).
ReplyDeleteIt would be nice to go out (re)visiting a pleasant scene from life, wouldn't it? Perhaps some combination of VR technology, meditation, brain stimulation etc. will make this therapeutically routine in the future?
You have to be careful with science like this. The man was an epileptic, his entire disease is overuse of brain neurons firing in a way thay are not supposed to. The title plays heavily into having an opinion before even looking into the study. Just beacsue there i activity there is no way we are able to say what the person saw, and if we do then they wouldn't be dead. Even if we could bring them back and ask the predominant amount of information they could give would be anecdotal and they would search for meaning in anything they may have experienced.
ReplyDeletePierce is right. 1 study of an epileptic is far from science. If this leads to further studies with acceptable data it would be an interesting read.
DeleteI really like the idea that before we die we get to see a glimpse of things that happened one last time. But I agree with what Pierce said about being careful with this kind of science. Since there is no way of knowing what a person could see in those moments, extremely reckless people who wouldn't do enough research on the subject could do things like bringing themselves to the brink of death to just find out what they could see.
