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.

Its interestng, but kidney cells are not exposed to patterns of neurotransmiters like nerve cells are. Cells can be reprogramed to be stem cells as well with the right pattern od signals but that does not mean that it really happens in the body.

Not to be a debbie downer here, but it's important to keep in mind that unless expressly stated otherwise, so-called discoveries that are only published in out-of-the-way (ie. not respected scientific journals) have usually not been peer reviewed or had their results replicated, which is the entire point of the scientific method.

"Muscle memory" is real.

Kind of like how there's taste buds in our lungs.

Memory is stored in the balls

Thanks i actually needed this comment to be here.

Just to recap, sperm, pee, microplastics, and memories are stored in the balls? Am I missing anything? I can’t remember. Maybe my balls are too full of microplastics to recall.

Urine is not stored in the balls. I'm a doctor you can trust me on this

[–] disguy_ovahea@lemmy.world 1 points 3 hours ago* (last edited 1 hour ago)

Even if you weren’t a doctor I’d agree with you. I was taught it’s stored in the bladder in ninth grade. Pretty sure that continues throughout your adult life. Lol

I'm sure you could fit a few dollars in loose change in there to.

The Soul is also stored in the balls.

Do you think that’s why we often tell god that we’re cumming?

And when you fuck someone, you're giving them your memories.

Its not the same memory as your brain. your life story is not in your non nerve cells. they have memory the same as yeast has memory but everyone is aware of how we have muscle memory in reptitive tasks.

[–] Xeroxchasechase@lemmy.world 12 points 7 hours ago (1 children)

I think muscle memory is just a phrase, but the training that makes and embed the "muscle memory" is essentially nural

[–] HubertManne@moist.catsweat.com 6 points 6 hours ago

yeah sorry I still feel that is neural just not all the way to the brain. I guess what I was trying to say if the article is not that cells hold your memory but that they hold their type of memories is a similar way.

Technically, a handgun also kills cancer in vivo. The problem is the cost to the host body.

[–] bizarroland@fedia.io 8 points 7 hours ago (1 children)

Okay but what you're saying is if I hired a good enough marksman to shoot the cancer out of my body without killing me then that's a good thing right?

I mean, that's basically what we do with gamma radiation and chemotherapy, just a little bit more ballistic, right?

Exactly! The only difference is that those use very tiny bullets.

Do we need to format our kidneys before becoming a donor now?

[–] Atelopus-zeteki@fedia.io 24 points 10 hours ago (1 children)

Maybe. There are numerous reports of people having changes in personality after organ transplants.

[–] Drunemeton@lemmy.world 8 points 9 hours ago

Damn, that’s interesting!

[–] troed@fedia.io 19 points 10 hours ago (1 children)

There are many stories on how the receiver of a transplant has felt themselves being "changed", sometimes in ways that would remind people of the donor.

MDPI is like the lowest quality slop journal. Like anything gets peer reviewed in that thing.

Is there an element of literality to the term "muscle memory"?

[–] Septimaeus@infosec.pub 14 points 9 hours ago* (last edited 9 hours ago) (1 children)

Yes, insofar as many reflexive actions, enervation and fiber recruitment thresholds respond to training, such that they “remember“ actions you have performed many times before. There are many clusters of nerves throughout the body called ganglia that are responsible for low-latency control of various functions that would entail too much delay when controlled entirely by the brain.

Generally, the minimum input-process-activation turnaround time of the brain is about 4 hz (240-250 ms) which is too slow for many applications of motor function. But the “co-processing” allowed by the extended nervous system enables the body to, with practice, execute far more rapid and complex action sequences in response to local stimuli. Some actions can be triggered and completed before a signal even makes it to the brain.

Thank you. For some reason it makes me happy to know that.

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.

Robert Heinlein, I Will Fear No Evil

"Elderly billionaire Johann Sebastian Bach Smith is being kept alive through medical support and decides to have his brain transplanted into a new body. He advertises an offer of a million dollars for the donation of a body from a brain-dead patient. Smith omits to place any restriction on the sex of the donor, so when his beautiful young female secretary, Eunice Branca, is killed, her body is used—without his knowledge and to the distress of some of those around him."

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.

[–] partial_accumen@lemmy.world 6 points 10 hours ago* (last edited 10 hours ago)

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.

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.

[–] partial_accumen@lemmy.world 6 points 10 hours ago

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.

[–] Endymion_Mallorn@kbin.melroy.org 5 points 10 hours ago

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