First-ever scan of a dying human brain reveals life may actually 'flash before your eyes'

livescience.com
By Harry Baker

The accidental finding was made when a man suddenly died during a routine brain scan.

After an elderly patient died suddenly during a routine test, scientists accidentally captured unique data on the activity in his brain at the very end of his life: During the 30 seconds before and after the man's heart stopped, his brain waves were remarkably similar to those seen during dreaming, memory recall and meditation, suggesting that people may actually see their life "flash before their eyes" when they die.

The phenomenon of replaying past memories when you die has been reported by some people who have had near-death experiences. But this is the first scientific evidence that this "flash" might be real. However, as this is the only case study, it is impossible to make further assumptions about how common the phenomenon may be or what the experience may be like.

Researchers made the startling discovery in 2016 while studying the brain activity in an 87-year-old Canadian man who had developed epilepsy. The team was performing an electroencephalogram (EEG) — a test that detects abnormalities in the electrical activity of the brain — to learn more about what was happening during his seizures. That's when the man suffered a sudden and fatal heart attack. The patient's unexpected death meant that the team had accidentally made the first-ever recording of a dying brain, the researchers said in a statement.

In total, the researchers recorded around 900 seconds of brain activity leading up to and immediately after the patient's death. This allowed them to see how his neural oscillations — repetitive patterns of neural activity, also known as brain waves — changed as he was dying. They found that in the 30 seconds before and after his heart stopped, there was an unusual change in his brain wave activity.

"Just before and after the heart stopped working, we saw changes in a specific band of neural oscillations," senior researcher Dr. Ajmal Zemmar, a neurosurgeon at the University of Toronto in Canada at the time of the man's case, said in the statement. These specific types of oscillations are known as gamma waves, added Zemmar, who is now at the University of Louisville in Kentucky.

Neural oscillations are classified based on their frequency and amplitude. Gamma waves have a frequency between 30 and 100 hertz, the highest frequency of any oscillations, and are most commonly observed in the brain when people access their memory center, in a region called the hippocampus, during dreams.

The team also gathered data on other types of oscillations during death, including delta, theta, alpha and beta waves. But it was the gamma waves that pointed toward the man replaying memories from throughout his life in his brain — a phenomenon known as life recall.

"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,"Zemmar said in the statement.

Experiments in rats have shown that the rodents also experience similar levels of gamma oscillations around the time of death, according to the statement. Therefore, the researchers speculate that life recall may be a universal experience shared by a majority of mammal dying brains, although there is minimal evidence to back this up.

But the researchers warned that it would be premature to conclusively state that life recall is a real phenomenon. The dying man was elderly and had epilepsy, which is known to alter gamma wave activity. This could have meant his brain activity during death was different from that of someone without epilepsy. Moreover, there is no way to know if the man was actually seeing, or perceiving, his past memories or if he was just in a dream-like state brought on by his failing nervous system.

Therefore, much more research is needed to make concrete conclusions about life recall, the researchers cautioned. The report of the man's case was not published until six years after his death because the researchers were hoping to uncover more case studies of dying brains to support their claims, but they came up empty-handed, according to the BBC.

However, the findings could provide a source of comfort to friends and family members during the "indescribably difficult" experience of losing loved ones, the researchers 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," Zemmar said in the statement.

The case report was published online Feb. 22 in the journal Frontiers in Aging Neuroscience.

Thank you for a very interesting read!

Very interesting. Thanks

If they would scan my brain one day...
they are going to find ALOT of Porn !

If they would scan mine they will find Aria Gioavanni Screaming for Vengeance!

I'm convinced if they scanned Nono's brain, they would find no activity at all.

Nah... he is probably talking about Mozart´"Don Giovanni" the
classical Opera, where Donna Anna runs from her father's house
screaming vengeance (in a muscial Aria) lamenting her feelings of hate — and love —
for Don Giovanni.

Correct!
I have never heard about this "Judsa Pirist" or what he wrote. Is it an old Lady from Kazakhstan?..

You Tube

In this part from 03:21 to 03:56 if you convert number of notes to the cuteness of lions (tricky, you must use a military graded software, but it can't be a problem nowadays) you can hear the words "Screaming for Vengeance" (if you have a good ear, ignoring violins when cellos and trumpets are playing you can HEAR every fuckin word!!!)

Actually it is the origin of her name, from her message board back in 2004

Screaming for Vengeance is originally the title of a very rare unreleased 1958 Tom and Jerry episode only available in the black web (the advanced dark web...) Best one ever!!!

In black web one can get all the 47 unreleased Metallica albums too. 46 of them are better than Puppets and Black albums together!!! Not kidding.
