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.

fascinating, this concept is a core to the theravadan buddhist practice of vipassana meditation, which is supposed to be what the buddha himself actually taught in his wandering classroom. I always took that bit with a grain of salt assuming it was just an old misunderstanding of what's going on but the kind of non-thought memories appears to be exactly what is described.

it's called Vasana and it's said to be like 'perfume lingering in cloth', the residual karma from our actions that shapes our future and influences automatic actions and preferences. Trauma is said to be stored in the body as well as Sankhara.

I have always viewed vipassana as mental martial arts more than religion, and brushed off all the reincarnation and other inexplicable stuff. fascinating to hear scientists confirming what philosophers came up with thousands of years ago.

“The Body Keeps the Score”

[–] _bac@lemmy.world 12 points 7 hours ago

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 not respected scientific journals) have usually not been peer reviewed or had their results replicated, which is the entire point of the scientific method.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.

Memory is stored in the balls

Still better that "pee is stored in the brain"

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.

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

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

If you're a doctor, then I'm a nun :)

[–] disguy_ovahea@lemmy.world 1 points 7 hours ago* (last edited 5 hours ago) (1 children)

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 thought you were referencing the conversation on Reddit or Twitter or something where someone had said "I'm a doctor, pee is definitely not stored in the balls" and then a really long argument ensued where the dude was pretty adamant that pee is stored in the balls. I just wanted to be the Dr

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 14 points 11 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 7 points 10 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.

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

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

[–] bizarroland@fedia.io 9 points 11 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?

[–] Endymion_Mallorn@kbin.melroy.org 9 points 11 hours ago (1 children)

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

[–] Liz@midwest.social 2 points 12 minutes ago

Chemo only applies if it's doped with a radionuclide, otherwise it's just regular poison.

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

[–] Atelopus-zeteki@fedia.io 26 points 14 hours ago (1 children)

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

Damn, that’s interesting!

[–] troed@fedia.io 19 points 14 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 13 hours ago* (last edited 13 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.
