We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Neuroscientists have recorded the activity of a dying human brain and discovered rhythmic brain wave patterns around the time of death that are similar to those occurring during dreaming, memory recall, and meditation. Now, a study published to Frontiers brings new insight into a possible organizational role of the brain during death and suggests an explanation for vivid life recall in near-death experiences.

I read this on the internet (maybe erowid? Lol) forever ago so who knows: but I heard your brain releases dumb amounts of DMT right as you die, which is also a chemical your brain elicits while dreaming

[–] [email protected] 5 points 1 year ago

Think I heard about this as well. It has to do with oxygen delivery or something. Your brain is running low on oxygen so it releases a chemical that brings it more and that chemical breaks down into DMT.

Does anyone in the bio field here know about this?

So they see their life flashing before them?

Sounds like it:

“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 speculated.

Perhaps the brain - in a last attempt to save its life - searches every situation that it has ever experienced to try to find survival tips.

Maybe it's making a final upload to the cloud.

YOUR LIFE

I was caught in a rip current, in close to zero Celsius salt water, with significant waves as a teenager. My wetsuit was inadequate, to say the least, and my surfboard was lost because the leash failed (think of it as a flotation device).

I was sure I was going to die. I didn't. But, yeah, every single second of my life was screaming through my brain while I pleaded with any force in the universe to save me.

I eventually got control of my breathing and swam across the rip and let the waves take me in. I was cold for a long time.

That was my first time surfing. Wasn't my last but I learned a lot that day.

The that took me there and loaned me the gear didn't even go in the water (said he was right behind me).

Where it will promptly remember I did fuck all and survived

Or, your favorite jerk off material. It's fifty fifty.

I can certainly see this as evolutionarily beneficial. When you're on the verge of dying and you suddenly have a recall of a lot of your experiences in life it may lead to you being able to survive.

I guess I won't since I have SDAM.

[–] [email protected] 2 points 1 year ago

I can't believe I haven't heard of that before! I thought my memory was just ordinarily bad, but reading about it I definitely have that.
