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.

Isn't the title misleading? A cell switching on the same gen neurons use to connect, if exposed to substance used to transmit information, doesn't mean it stores or transmits any memories. It seems it doesn't even do anything more, like forming dendrites or "answering" chemically.

Guess that's just a side-effect of how the gen is exposed.

It's more than that. People who have had heart transplants can inherit memories and personality traits from the donor. Cells remember more than they let on and can pass these memories to the recipient.

See this study. I think it's safe to say we have some empirical evidence for this. In the linked study, there's a kid who received a heart from another kid who died trying to retrieve a power ranger and somehow the donor knew that without anyone telling him. Another kid received a heart from a kid who drowned and he became afraid of water.

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.

Isn't this literally the plot to the Reanimator?

Well, it's certainly the plot of Assassin's Creed

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.

Is this the stuff responsible for organ donation receivers picking up traits of the donor?

[–] AeroNaut@lemmy.world 4 points 3 hours ago* (last edited 3 hours ago)

Likely not that simple as there would be other factors at play, but good way of thinking. I'm no geneticist but that sounds like it may be a contributing factor, though memory in this case would be functional rather than personality-based.

Memory is stored in the balls

[–] 100_kg_90_de_belin@feddit.it 4 points 11 hours ago

Still better that "pee is stored in the brain"

[–] disguy_ovahea@lemmy.world 45 points 1 day ago* (last edited 1 day ago) (14 children)

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.

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

[–] bizarroland@fedia.io 12 points 21 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 11 points 20 hours ago (1 children)

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

[–] Liz@midwest.social 6 points 9 hours ago

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

[–] HubertManne@moist.catsweat.com 28 points 22 hours ago (1 children)

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 17 points 21 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

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

[–] Atelopus-zeteki@fedia.io 33 points 1 day ago (3 children)

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

[–] RestrictedAccount@lemmy.world 5 points 4 hours ago (1 children)

Many stories like this from fecal exchanges (trans-poo-sions)

[–] Atelopus-zeteki@fedia.io 3 points 2 hours ago

Yes, that is also true. Many things make up the mind, and changing a major input, e.g. the microbiota that make a particular mix of short chain fatty acids and other neuro effective compounds, is going to change the cognitive outputs.

[–] Lumisal@lemmy.world 7 points 8 hours ago* (last edited 8 hours ago)

To be fair, I think anyone going through something as traumatic as basically being put into stasis and having their heart cut out and and then having one reattached would change a bit simply because of the process.

I mean, you don't keep stepping on Lego bricks barefoot after you've done so, and we expect people who have had a heart ripped out and then another one reinserted to act the same?...
