Harrowing simulation shows what happens to your brain when you die

A mind-bending simulation has revealed how our brains can remain active even after our bodies are officially considered dead.
Whatever you think about death, a pretty general idea is that it occurs when the brain shuts down, our heart stops beating, and we stop breathing.
There's mixed thoughts on what happens to our souls or our consciousness after that, but whether you believe in the afterlife, a transfer of energy or simply nothing at all, you might be surprised to learn that your brain could actually still be working away for a couple of minutes after your body officially calls it quits.
This process has been demonstrated in a simulation by YouTuber Zack D. Films, which explains how the brain undergoes a 'surge of activity' right before death.

This causes a type of 'electrical wave', the simulation continues.
"These waves activate parts of the brain associated with memory and consciousness and this can continue for up to two minutes after death," Zack D Films goes on, though he noted there isn't a known 'biological reason' for this sudden surge of life at a time when everything else is coming to an end.
This surge has been noted in studies, such as 'Surge of neurophysiological coupling and connectivity of gamma oscillations in the dying human brain', which was published in the Proceedings of the National Academy of Sciences.
In the study, scientists recorded the brain activity of four people while they were dying and found bursts of activity in their brains after their hearts stopped.
Sam Parnia, a pulmonologist at New York University Langone Medical Center, said the study suggests they were 'identifying a marker of lucid consciousness', while Ajmal Zemma, a neurosurgeon at the University of Louisville, suggested that gamma waves can signal that different parts of the brain are working together to essentially create the image of an object or a memory.

Zemma noted that how the brain does this is 'one of the biggest mysteries in neuroscience,' but seeing those same gamma waves in a dying person suggests a biological mechanism for the idea of the brain replaying memories in our final moments.
The simulation lays out this thinking, explaining: "Now since there isn't a biological reason for this to happen, some researchers believe that the brain is pre-planned to do this, giving you a chance to recall memories one last time."
Responding to the information, one user wrote: "I like the idea of these last few minutes being a feeling of total euphoria like you've never felt before in life.
"To comfort you during something so frightening."
Another viewer responded: "Wait that's actually so sad though. It's like the brain is trying to comfort you and itself before dying by using your best memories."
"Your life flashes before your eyes makes so much sense," one user noted.
