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.

        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?

    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.

    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.

        If I read the cited sources and they turn out to be a bunch of untested hypotheses based on poorly conducted studies… I’ll be mad.

        Just skimming through it makes a bad first impression.

        …I’m not even trying to be derisive. I’m just really angry at how much “there’s a study” has become “there’s proof”. And I shouldn’t even be mad because communicating that difference should be the authors’ job.

        If you value your time, don’t read any further because I’m just going to vent a little:


        So I lack any formal education (apart from ficking school). The best thing I can say about myself is that I can hold and mostly understand a conversation with people who are actually educated in their field.

        But some studies are bad. Like bad-bad. So bad that I think, most people who can read should be able to recognize their flaws if they actually read them.

        For example:

        I read a study a while back about genetic (as opposed to learned) prepositions of monkeys in relation to their biological sex and preference for toys.

        The methodology was bad, but here’s the shittiest part imo: At the end of the study, the researchers found that of the 130 or so monkeys, only about half showed any preference for any kind toy. So the researchers excluded the unbiased monkeys from the test. Of the remaining monkeys, still only the males showed any preference for the “male” toys. So the females were also excluded. In the end, only 30 monkeys actually counted, because they showed the hypothesized difference in their preferences. And even those only showed a delta of 10-30% in the time they spent with the toys.

        The study should have concluded that most monkeys don’t give a shit if a toy has wheels (like a shopping cart, which apparently makes it a “male” toy) or if it’s soft, like a plush (which is “female” because boys would never touch a plushy, of course).

        Instead, they found that their hypothesis turned out to be correct, after disregarding anything that invalidated their hypothesis.

        Where did I get this study from? From social media, of course. Where a bunch of meat heads “proved” that all women genetically want to be tradwives and trans people don’t exist or some shit.

        Fuck everything about this.

        I’m all for implications but I think a little higher level of standards should be practiced since this is c/science.

        The title is “misleading” because they’re not talking about visual/conscious mind memory as you’re doing here.

        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 suggests that in the future, we will need to treat our body more like the brain — for example, consider what our pancreas remembers about the pattern of our past meals to maintain healthy levels of blood glucose or consider what a cancer cell remembers about the pattern of chemotherapy.”

        Furthermore, you’ve jumped onto anecdotal evidence and have declared it Empirical with your linked study

        A literature review was performed to explore accounts of personality changes following heart transplantation … Further research is recommended.

        That level of evidence would mean anyone claiming body transfers, alien abductions, past lives memories, etc etc would all be empirical data we must now scientifically accept.

        I don’t see how you’re linking the two studies with the implied “It’s more than that”. The original study from OP is declaring nothing about actual memories that we’re “consciously using” being stored in other parts of the body. It’s stating they believe cells have “memory mechanisms” to better function, like a processor getting it’s own memory cache (that data storage is used for it’s processing purpose and isn’t included with your harddrive access).

        They are a little deceiving/misleading with the article as well,

        The goal of the research was straightforward — to investigate if non-brain cells contribute to memory… They ingeniously engineered the non-brain cells to generate a glowing protein, which indicated whether the memory gene was active or dormant… Not only does this research on non-brain cells introduce fresh perspectives to study memory, but it also holds promise for potential health-related benefits.

        They tested a gene by bombarding cells with chemical cocktails, showing the gene can be activated. It’s a giant leap to then say we have empirical data that we store memories throughout our bodies.

    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.

      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.”

      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.

        Wow, these examples are so cool.

        Food Preferences:

        • developed aversion to meat after receiving a heart from a vegetarian donor.
        • experienced nausea after meals post-transplant from a donor with irregular eating habits.
        • developed a taste for green peppers and chicken nuggets, foods favored by her donor.

        Musical Preferences:

        • began enjoying loud music post-transplant.
        • developed a love for music after receiving a heart from a musician.
        • started appreciating classical music, previously disliked, after transplant.

        Sexual Preferences:

        • Male recipient of a heart from a lesbian artist experienced heightened desire toward women.
        • Lesbian recipient of a heterosexual woman’s heart found attraction to men.

        Other Preferences and Aversions:

        • Landscape artist’s heart recipient developed interest in art.
        • Dancer’s heart recipient shifted color preferences to cooler tones.
        • Fear of water developed post-transplant from drowning victim.

        Memories:

        • describes sudden unusual tastes accompanied by thoughts about their donor’s identity and life experiences.
        • feels tactile sensations corresponding to the impact of the car accident that killed their donor.
        • experiencing flashes of light and heat resembling the trauma suffered by their donor, who was shot in the face.
        • describes a vivid dream of reckless driving, mirroring the circumstances of their donor’s fatal motorcycle accident.

        Some recipients even experience dreams or memories aligning with their donor’s identity, such as a woman envisioning a young man named Tim during a dream and later discovering her donor’s name as Tim Lamirande

        Unfortunately, though, I don’t see any mention of how certain they were that the recipients didn’t learn these things before experiencing them

    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.

        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.
