In this study, the scientists simulated the process of spaced learning by examining two types of non-brain human cells — one from nerve tissue and one from kidney tissue — in a laboratory setting.

These cells were exposed to varying patterns of chemical signals, akin to the exposure of brain cells to neurotransmitter patterns when we learn new information.

The intriguing part? These non-brain cells also switched on a “memory gene” – the same gene that brain cells activate when they detect information patterns and reorganize their connections to form memories.

It seem like they're just saying kidneys remember kidney stuff, pancreases just remember pancreas stuff, etc etc.

It's not like your kidney remembers Aunt Jean has a mole on her nose.

There is another body of research that deals with a person's behavior can be heavily influence by endocrine actions. Organs can affect current endocrine responses. So there is a suggestion here that your kidney may not remember the Aunt Jean has a mole, it may remember why it releases certain hormones which can effect how you behave.

Yeah, but if you get someone else's kidney, it "remembers" how that body worked.

Read something like that in an old science fiction novel.

Old man's brain is placed in a young woman's body. Her brain was destroyed but most of her memories live on in her body.

I'd read that novel.

Old man hell bent on world domination, but really wants Johnny in math class to ask him to the dance on Friday.

Reminds me of the guy that got a heart transplant and took up smoking like the original owner of the heart and started dating the original owners ex.

One of Iain M. Banks' Culture novels has an exceptionally old character who is so exceptionally old that he's had to turn most of his body into memory storage (sounds weird if you think in terms of computers) to keep remembering things. He stores his sexy memories in his balls.

Don't remember that char, can you refresh my memory (I am fully aware of the irony given the topic under discussion)

So hold on a minute - does this mean there might be some truth to the whole “eat your fallen enemy to gain experience” thing? That’s wild.

[–] rowrowrowyourboat@sh.itjust.works 6 points 15 hours ago (1 children)

No, because you're eating the flesh, so you're digesting it.

This is more relevant to organ transplants.

Apparently, it's a known phenomenon that some organ transplant recipients seem to inherit some traits and even memories of organ donors.

I was wondering if there is a link between cellular memory and how trauma is encoded into DNA?

[–] Wolferatu@lemmy.zip 2 points 15 hours ago

I suppose that explains survival instinct

[–] Korkki@lemmy.world 2 points 15 hours ago

As if haven't know for a century that immune system has the ability to both form memories and problem solve, that rivals the brain. The body being able to adapt to external stimuli isn't anything groundbreaking.

[–] oce@jlai.lu 1 points 15 hours ago (1 children)

I wonder if that contributes to "muscle memory".

[–] catloaf@lemm.ee 8 points 15 hours ago (1 children)

No, "muscle memory" is the nickname for practiced motions.

[–] oce@jlai.lu 2 points 15 hours ago (1 children)

I know it is a nickname, I am wondering if this could contribute.

[–] homesweethomeMrL@lemmy.world 1 points 14 hours ago

Maybe in the sense that memories are not required to be in the brain to - have an output?
