A new study publish by the scientific journal Frontiers in Aging Neuroscience, title ‘Enhanced Interplay of Neuronal Coherence and Coupling in the Dying Human Brain’, reveals that the old saying is true, Our brain might replay key moments of our lives as we go from this world.
You could understand that you might see your lives play out in front of your eyes like a movie, as per the data collected from the brain scan of a dying person at the exact moment they gave their last breath.
Gamma oscillations of the brain in that instance were comparable to moments where we are deeply focus, dreaming, or remembering something.
The study points out previous anecdotal evidence of individuals who, after going through Near-Death Experiences, tend to remember flashbacks that have link to the brain’s oscillatory activity.
This discovery, which collect data of an outburst of gamma activity in a dying brain, occur by chance.
A group of international researchers was following the checkup of an 87-year-old patient with epilepsy.
The research team was scanning his brain when he pass away.
Before that, they manage to get an image of the final moments of his mind, with a big surprise.
Another scientific finding from this study is that brain activity continues for some 30 seconds after the heart has cease its functions.
This is the first time that the brain activity of a person has fully register in the minutes before and after passing away.
This has done before, with other species, though the moral implications of these experiments are dispute.
Experiments with rats back up the observation of this test.
They show up to 30 seconds of a very high level of brain activity after the heart has stop.
The idea that the brain continues to work after the heart stops have always seem more fiction than fact.
It was always said that the eyes of those who pass through the guillotine would give a final glance after being behead.
It could be true, given the results of this research.
Our fascination with life, death, and the line in between have not only generate scientific speculations, but also all sorts of religious and mystical theories and, of course, a good amount of ideas to the realm of fiction.
Another common element of those with near-death experiences is their perception of walking towards a guiding light.
A study, done with rats by the University of Michigan, attributes this vision to a final explosion of brain activity right at the moment of passing on, as per the BBC reports.
Psychologist Jason Braithwaite, a professor at Lancaster University, defines that guiding light as the “last hurrah” of a brain before it shuts off forever.
The final sunbeam languishing over the horizon.
If the brain is going through the key moments of our lives just before expiring, it’s comforting to think that it’s signing off by remembering some of the most beautiful instants of our existence.
It’s almost impossible to replicate the study publish by Frontiers in Aging Neuroscience.
Maybe we can do it with animals, but there’s an increasing number of moral and legal limitations about that.
In short, it’s been proven that there’s an outburst of brain activity during the moment of our demise, and that such activity has the same gamma waves that we have while reminiscing about our past.
The brain continues to function for at least 30 seconds after the last heartbeat.
This matches a previous study done with rats.
So whatever we believe that happens after we shuffle off this mortal coil, no longer belongs to the realm of science.
May be individual beliefs can provide a satisfactory answer to that question.
