I would love to see you take a deep dive into cognative/behavioral relationships to engram learning. A lot of people struggling with trauma related memory issues (inc. PTSD) would likely benefit from understanding how their brains physically learned (and could un-learn). In fact, it seems to me many therapists could also do with knowing more about learning and plasticity.

Check out Johannes Graff's research. He talks about the critical window during which a memory can be reupdated to decrease aversion or fear - improving therapy for PTSD. And yes, therapists do know about those concepts, but research into how they can be implemented safely needs more data. For ex: if the reupdating of the memory is not done carefully, it might lead to increase in fear rather than decrease (because you are recalling the fearful memory and not reupdating it to a positive one)

But it seems that the co-retrieval of 2 distinct engrams increases the engrams on both sets.Or because the new linking engrams only contain the linking information, so that doesn't count the original size of the 2 engrams?

Amazing point, thank you! I also had this very question while I was creating the video, but I'm afraid I don't have a great answer. The source paper for this finding ( pubmed.ncbi.nlm.nih.gov/28126819/ ) just reports an "increased overlap" but doesn't compare overall sizes (or I just missed it). My intuition is that the "reorganization" would mean that some non-overlapping neurons become excluded from the engram to keep the density constant, while increasing the overlap. But your interpretation with "linking information" is equally plausible 🤔 If you find the answer, please let me know!

Hi, really interesting to learn about the waxing and waning of neuron excitability. Makes sense why there's just some things that are easier to process depending on the time of day. There's one more thing you can add to the reason why only some neurons are selected for an engram, and that is that when one neuron fires, it raises the action potential of the area outside of its membrane, which in turn locally raises the threshold needed for other neurons to fire. If there are two neurons equal in excitability and one of them happens to fire first, the second one may not fire because of the heightened action potential required. Love watching your videos, very inspiring and well communicated!

@@Gorulabro I don't disagree with you that it's not necessary for us to copy the nature of 1-1 to have similar "functionality". Now I would say that you need to be very careful with your definition of "functionality". Because then, there is no functionality similar to the brain in artificial neural networks if we consider functionality as the set of qualitative experiences that imply a certain general behavior in the system, for example, ANN's are terrible for having several things that would require them to have a qualitative representation of the world and whose functionality in fact cannot be simulated by a computer. On the other hand, we can make excellent mimics of "functionality" in the external sense, something that merely reproduces a desired external behavior, as ChatGPT does with producing texts that appear "intelligent" and aware. There are reasons why we don't make planes with flapping wings as well that go way beyond that, and some birds actually just glide most of the time and just use their wings as a way to lift themselves up, but nobody says planes are simulations of birds and nor that we are functioning like birds. The general similarity of a bird and an airplane is the same as that of a bird and a firearm projectile or a ballistic missile, both are "flying" in some sense, but it doesn't seem to me that it makes sense to say that having this "functionality" similarly let us translate this knowledge into terms of what goes on in birds, as many people try to do by saying that AI's somehow have an inner workings close to what goes on in human consciousness. It takes a lot of care to do these analyses, but in terms I don't disagree with you that these are efficient means of approaching something that refers to the intelligent external behavior that we seek to automate.

nice job man... one of my top youtube sources for up-to-date neuroscience without dumbing down

If the brain codes parts of a memory in different areas of the brain this might explain why some sounds and smells would bring you back to something like a childhood memory. If differant areas are responsable for different portions of memory then a small triggering of one of those stimuli might cause a cascade of associated brain regions to in response

wow... so many questions about this one... 1. Is memory encoded in the structure of neuron interconnections, or the pattern of action potentials buzzing through web of neurons? Given a network pattern of dendrites, axons, and synapses is the memory "still there" even when no signals are being passed? 2. How can repetition strenghten memory, when talking about the physical connections between neurons? 3. On gene activation when memory forms, what is the timescale of this process? remembering can be pretty fast.. can genes be expressed (and make lasting changes) just as fast? 4. How far can we "isolate parts of a memory": with mice fear conditioning, how can we be sure that the pain of shock is linked to the sound stimulus only, instead of sound stimulus + a given position in the lab + objects, shapes, and colors around the mouse at that time + ambient smell +.... , other things that might also be encoded in the engram? 5. If two different mice went through fear conditioning with the exact same setup, would we see a difference in the engrams of each mouse? 6. lets say we subject a mouse to fear conditioning, and observe the engram. We then wait for some time until the mouse forgets that experience (weeks? months?). If we do fear conditioning again on the same mouse, would the same engram be formed? 7. Can the idea of engrams be used to estimate the memory capacity of a brain? we know it can't be infinite because the brain is a physical substrate 8. Can we induce the growth of new linking neurons between two engrams chemically/biologically? so instead of the mouse retrieving two memories simultaneously and getting those memories linked, we "link" two memories artifically with those two memories have nothing to do with each other before 9. we know that the brain is not the only component of the central nervous system. Are memories (related to reflexes) encoded in the spinal cord in the same way as they are in the brain?

7 is not guaranteed if mind body dualism is true. Then the combination of neuron activation acts as an indexing/lookup function. The combination of millions of neurons is fundamentally 10^1,000,000 and we have billions if not trillions. Even 10^80 would be a memory per atom in the universe

Do we currently know how brains "check for overlapping" in separate engrams? Also, is it possible for completely unrelated memory clusters to randomly have similar engrams/engram positions, causing them to be intrinsically linked, and, if so, how often/how likely is this to occur?

I think of stuff like this all the time, the existence of the universe is just so immense and mind boggling. Crazy how were just going along with it all.

Hi there, I had a question. Why aren't memories overwritten / replaced during co-allocation? To me it seems that when stimulus 2 occurs (within 6 hrs of stimulus 1), the memory associated with stimulus 1 should be replaced with the memory associated with stimulus 2 (since the same neurons, who's excitability is the highest outcompete the neighboring neurons for storing that memory in that engram). Or is it possible for a single engram to host multiple memories?

@Youtuberboi596

10 ай бұрын

From my understanding of Artificial neural networks, neural nets are really good at reusing connections and neurons to store different information, basically they are awesome at compression of all sorts of data because each neuron is tuned to be able to be used in different pathways and play a different role in each pathway. So I think, in organisms, new similar memories is just new surrounding neurons participating and all the previous involved neurons adjusting to accommodate most important memories + new memories (which may be similar). I think this is why we start to forget old stuff when we learn new stuff, but we can revive that memory easily by a little relearning. It's just neurons trying to optimally compress information. Just a theory tho, I might be wrong. Btw, look at 20:42, you can see 2 new neurons involved due to the second stimulus

if we were to implement all these behaviors as agents that will behave and act throughout time, and each neuron is a deep neural net on its own, I think it is possible to replicate a digital artificial human brain. It seems like we have a few puzzles here and there already and as the research goes on, when more and more findings get implemented into code it is definitely doable. The disappointing part of NN right now is that it doesn't get trained like how brain is at the moment, everything is fed into the model and will activate a bunch of nodes unlike what we see here only few highly active neurons is activated, we can use some dropout and stuff, so maybe the dropout signal is out transmitted to neighboring agents shutting down neighbouring agents made of DNNs to make them less active, and maybe each agent can be spawned or despawn to make the entire thing dynamic so say 2 mappings got fired at once new agents spawn in and linked them together etc... and there are more questions ahead like how do you train them and how everything is going to work out in math, it will surely be an interesting research to do.

@antonystringfellow5152

10 ай бұрын

No bytes at all. A byte is a series of eight bits (ones and zeros). Neurons don't function with ones and zeros. Neurons are not digital, they're analogue. Synapses are analogue. This gives them a much greater capacity than a transistor in a processor, which is only used as a switch and as such only processes two values (ones and zeros). Today's neural networks merely simulate neurons and synapses, digitally. They're a far cry from the real thing. Neuromorphic processors that are analogue are being developed by several companies. These emulate rather than simulate neurons and synapses. Very promising technology, which offers such advantages as more computing power for less energy and an inherent ability to continuously learn rather than requiring a resource-hungry training process. Unfortunately, though, the size and density of the components are currently nowhere near a match for the latest GPUs, such as those produced by Nvidia. This is probably why Nvidia is showing no interest in developing its own yet - it's doing a great job with GPUs.

Thanks you for this video, I am not usely writing comments but I have to say that you really did an incredible job of pedagogy in this video. Usely I need to see your videos sevral time to understand all and in this one it was so clear that only one is enough.

Thank you!

I am baffled by how simple you’re making this sound. I’ve always been curious how brains work, and binging your videos has totally made it made sense

This whole video brings to mind the nature of trauma, how it is ingrained, and ultimately how it can be untangled.

High quality video. Loved it. Imma sub.

Great Work!

This video is excellent! Thanks!!!!!

Really good, gradient pedagogy, emphasis on clarity. I'll check out the rest of your channel. Smarter-faster.

Amazing video! Thank you!

This is very very interesting. thank you.

I can’t wrap my head around memory. Wild stuff.

Is there a way or does there exist a sort of transcript of this video with citations linked to specific parts? I would love to be able to scroll though it while watching the video and be able to access papers!

Thank you for the idea! I must admit that currently, all the transcripts are stored on my laptop with citations inserted quite haphazardly. I've actually been contemplating making them accessible for a while now. I hope to launch a website in a few months and publish blog-post versions of the video scripts there

What i took from this was,brain stores info into multiple sparsely populated graph like structures, which on co-allocation or co-retrieval are connected by adding some nodes. Also neutrons of an experience are well spread apart in the brain, maybe so that, in eventual co-retrieval some neurons can be left to facilitate connections. Also since sparse graphs and planar graphs are easier to traverse, maybe some processes also handle some form of garbage collection aiming at those neurons.
