There are probably few experiences you could have
that would confuse your brain more than almost dying.
Hey friends, Laci Green here for DNews.
“Near death experiences” have been describedby people across the world
who came, or thought they were coming within an inch of their life.
神奇的是 无论你是谁 来自何方
What’s totally crazy is that no matter who you are,
where you come from, everyone describes it very similarly.
It starts with a warmth spreadingthroughout their body,
absolute serenity and calm,
some might even call it nirvana.
Then comes a bright light and a feeling
of being detached from the body, as if you were floating.
The number of people who have
a near death experiences is on the rise, thanks to technologies
that can save people at the last moment. Naturally,
there’s a burning question:
WHAT DOES IT ALL MEAN!??
This is a complicated and emotionally chargedquestion.
For some, the near death experience is proofof the afterlife.
For others, it’s a fascinating neurological question.
Let’s take a look at this phenomenon througha scientific lens.
One of the most highly regarded studies on NDEs
comes from the University of Kentucky.
They found that some Near Death Experiences may actually be
something called REM intrusion.
During REM intrusion, the mind awakes before the body,
which can trigger hallucinations.
It’s sort of like dreaming – while you’reawake, kind of.
I covered this phenomenon in my video about sleep paralysis,
If you’re interested you should definitely check that out
cause it’s some freaky stuff.
Because REM intrusion happens in the brainstem,
it’s possible for this to occur even when
higher functioning parts of the brain have gone dead.
Building on this research,
trauma to the brain can result in a sensory mix-up.
As your brain struggles to stay alive,
all of that chaos resulting in an information overloading in visual cortex.
This is known to produce visions of a bright light or a dark tunnel.
The brain also releases a flood of happy endorphins
which put you in a profound state of peace and calm.
And because your brain is responsible for
for orienting your body relative to everything around you,
trauma and oxygen deprivation can cause
a sort of out of body experience.
This has been observed in lots of people
who aren’t having a near death experience as well.
Lastly, a new study has been published by the
by the Proceedings of the National Academy of Sciences on NDEs.
The study was done on rats and they found that
after cardiac arrest, there is a crazy spike in neural activity.
The lead author says that”if anything,
the brain is much more active
during the dying process than even the waking state.”
Essentially, the neurons go into overdrive as death sets in,
causing the brain to go haywire in a predictable way.
感到暖意 看到白光 感觉轻飘飘 等等
cue warmth, bright light, floating, etc.
We perceive this experience with profound intensity
as our brain takes a last hurrah before death.
我说不出这种感觉是美好 可怕 压抑 还是什么
I can’t decide if this is beautiful or terrifying or depressing or what.
