Brain found to store three copies of every memory
- Olesya111 2y ago[dead]
- spacebacon 2y agoHow does 3 regions of the brain translate to 3 copies of the same memory? With entanglement they all work together to form the one memory no? I’m not convinced the same memory is even isolated to one brain.
- dustypotato 2y agoAre you talking about neuronal clusters in other parts of the body
- spacebacon 2y agoI theorize Information may simultaneously entangle neurons around the world. Not just a humans brains.
- dymk 2y agoPlease elaborate, this sounds fascinating
- spacebacon 2y agoI sincerely appreciate your interest. Let’s start with familiarizing with a large collection of sign systems we know about… https://github.com/space-bacon/SignSystems/blob/main/Codex-of-sign-systems.md https://github.com/space-bacon/SignSystems/blob/main/Codex-o...
- spacebacon 2y agoEach of these systems contribute to information. They may be closely entangled (compared to say a rock on mars) or have more entanglement due to proximity. This “entanglement” may relay universal truths or even advanced theories on itself at the speed of information.
- trunch 2y agoIntrigued by the project, love the idea of exhaustively exploring significance for arbitrary input. Think you need to provide a few example inputs and outputs on the github for the program. Also not sure a project focused on decoding meaning and signals benefits from having AI generated interpretations divorced from the inherently human act of sign interpretation. Can be seen in the md file, such a rigidly enforced structured output has forced it to give some averaged amount of weight to different categories and examples, when many are facets of each-other, or purely just expressions of something mentioned earlier. I can see free-form high-temperature llm outputs fed to another model, which serves only to aggregate their core interpretations, providing more insight than what's within the document currently.
- spacebacon 2y agoThanks, I agree with that input. What are your thoughts on this from a conceptual lens? https://github.com/space-bacon/Semiotic-Analysis-Tool https://github.com/space-bacon/Semiotic-Analysis-Tool
- detourdog 2y agoI see what you are saying. It may take three regions of the brain to activate to form a memory.
- a3n 2y agoI had the same question as your first sentence. I'm not sure I understand your second sentence, as I don't follow "entanglement news." Is entanglement currently being seen as taking part in everything, everywhere? Specifically in brain processes? I'm intrigued by your third sentence. I look forward to more sentences.
- rcxdude 2y agoThere is a (decidedly non-mainstream) idea that brain processes involve large-scale quantum effects, that quantum effects beyond just the normally expected biochemistry are essential to the functioning of the brain. There's not really much empirical evidence for it, and about the only theoretical argument is that the brain is much more efficient than a computer. I think people tend to like it because it makes brains (or more specifically human minds) feel more special.
- jncfhnb 2y agoQuantum mechanics and consciousness are both weird and therefore are equivalent
- Flop7331 2y agoI saw that movie. It also tried to put water memory across as fact.
- zoklet-enjoyer 2y agoThere's a guy in Twitter who thinks that the brain is an antenna that receives consciousness, or something like that. I'll see if I can find it, but it's kind of hard to navigate Twitter since I got banned. Edit: I couldn't find it. Something about microtubules
- wizzwizz4 2y agoAre these microtubules located in the Pineal gland?

- RaftPeople 2y ago> How does 3 regions of the brain translate to 3 copies of the same memory? The actual paper goes into more detail: https://www.science.org/doi/10.1126/science.adk0997 https://www.science.org/doi/10.1126/science.adk0997 Here's a blurb from the paper that partially answers your question: > Late-born neurons were preferentially recruited for retrieval at short latency after acquisition, whereas early-born neurons were preferentially recruited at later times. These divergent trajectories recapitulated reactivation dynamics recorded through longitudinal calcium imaging experiments, which further revealed distinct network-wide responses between subpopulations.

- chubot 2y agoThis is profound!
- datameta 2y agoEncoded differently of course, removing bias.
- doubled112 2y agoWhen there is a discrepancy, how do you know which is correct?
- datameta 2y agoIs it the case that one or the other are more correct? Or rather, in which case are we judging one to be more accurate based on what criteria?

- _heimdall 2y agoI don't quite follow their leap from seeing three distinct regions and types of neurons firing to the proposal that each is storing a separate copy of the memory. Anyone have an idea of how they make that leap? Or are the researchers getting ahead of their skis, assuming that neurons lighting up means the memory is directly stored there as opposed to those neurons simply being part of the process?
- uhmpire 2y ago[dead]
- az09mugen 2y agoMaybe there is a thing like the precogs in Minority Report, the storage is presumably made in different places because memory can deteriorate and when you need to recall it there is a "vote"/synchronization between those different places ?
- _heimdall 2y agoAnything is possible, I just don't see scientific data in the research that points to anything other than "these areas light up." It's a huge field of research though, I'm by no means an expert.
- iambateman 2y agoI think the evidence for this should be extraordinary because it is so apparently unlikely. Why would the brain store multiple copies of a memory? It’s so inefficient.
- gchamonlive 2y agoMaybe if you think of it as hard drive, but a biological mechanism might benefit from multiple pathways that can potentially trigger.
- austin-cheney 2y agoOn a small level computers do that: cpu cache (itself 3 levels), GPU memory (optional), main memory, hdd cache. The reason why animal brains would store multiple copies of a memory is functional proximity. You need memory near the limbic system for neurotic processing and fear conditioning. Long term storage is near the brain stem so that it can eventually bleed into the cerebellum to become muscle memory. There is memory storage near the frontal lobes so that people can reason about with their advanced processors like speech parsing, visual cortex, decision bias, and so forth.

New research suggests that our brains make two copies of each memory in the moment they are formed. One is filed away in the hippocampus, the center of short-term memories, while the other is stored in cortex, where our long-term memories reside. From https://www.psychologytoday.com/us/blog/the-athletes-way/201704/mit-scientists-identify-brain-circuits-memory-formation https://www.psychologytoday.com/us/blog/the-athletes-way/201... : > Surprisingly, the researchers found that long-term memories remain "silent" in the prefrontal cortex for about two weeks before maturing and becoming consolidated into permanent long-term memories.

What is the survival advantage to redundant, resilient recall; why do brains with such traits survive and where and when in our evolutionary lineage did such complexity arise?
- jncfhnb 2y agoGarbage article https://www.science.org/doi/10.1126/science.adk0997 https://www.science.org/doi/10.1126/science.adk0997 The paper is about how the brain seems to encode memories and re encode them over multiple groups of differently aged neurons; with younger neurons being more plastic). Nothing like saying “brains store three copies”
- gyomu 2y agoYour comment is too late, I already launched my startup that stores data in 3 databases calling “patent-pending human biology based neural retrieval” and raised a $15M series A
- monstertank 2y agoIt is to create a 3 dimensional object to use in a holographic UI like in Minority Report. How else are you going to look at it from other perspectives?

- foota 2y agoImagine if we found a biological system doing Reed Solomon coding
- oglop 2y agoNature loves redundancy. Milton Friedman needs to lecture nature on efficiency and economics and show off the modern marvel that is the US economy. Maybe nature would get its act together and stop being so wasteful.
- stuckkeys 2y agoAnd when I try to recall something, nowhere to be found.
- doodlebugging 2y agoBased on some of the replies here it appears that you probably just need to get re-entangled with some of your friends who were there at the same time.
