why are the mice not allowed walls made of natural material in these tests? the wee mice dont deserve such bad treatment anyway. Their theta and alpha etc waves are probably experienced as response sensation just like ours. Would natural materials, if carefully chosen, prejudice the results? or would they enhance the real feel for the mouse and therefore the interpretation its brain wave types?

@@maiamaiapapaya "The more I learn about biology in general, the more I feel like us being here right now is a miracle." While I understand the feelings, I think that we have not destroyed ourselves yet is the real miracle. ;) Seriously, though, I see things differently. That we are here is due to everything that came before. Much the way that starting a walk down a path one cannot see more than a very small distance ahead, one with billions of branches in the path, one that travels billions of miles/kilometers (pick your favorite), we are here without actually having decided to be here. It may seem like a miracle that all of those billions of choices wound up with what we are today, but I posit, what if we could be better. Not just a little better, but a lot better. Looking at other life on Earth, you will find lots of *decisions* made over time that make different creatures far better at some things that we are. Better vision, sense of smell, resistance to cancer, resistance to disease, and so on. While human beings have these large brains that seem to be more capable in many ways than the brains of other species, there are abilities that our brains do not have that we find in other species. Then there are the basic physiological issues. Choking to death due to the mouth being used for eating, drinking and breathing (whales don't have that issue) being one of those. There are Genetic mutations that go wrong. Malformations in babies, fetuses that die in the womb, non-viable pregnancies (tubal for instance). Again, an incredible array of genetic and other physiological failures. There is so much about what and who we are that is problematic and could be improved upon. We have the abilities to do so. Yet, the vast majority of people choose to squander what they have inherited or been given. To me the miracle has yet to happen. That would be the miracle of "we the people", all of us, taking responsibility not only for our lives today, but what we leave to the life that follows us. The miracle of understanding that every decision has weight and consequence. The miracle of deciding to make the world, life, and living better for all that follows. My spouse does accuse me of thinking to much though.

Beyond impressed with this video! I'm a first-year PhD student and this video effectively summarized so many papers I've been reading recently. The visuals are stunning and the teaching so effective. Thank you, Artem!

the explanation graphics and analogies are so awesomely understandable. thank you so much for doing this!

Currently writing my thesis on alternative learning algorithms and this video was a gold mine. From my research I already had a strong intuition a clock was essential for efficient representation learning, but I was having a hard time finding proper references that sustained this idea. No more, thanks to you! Great break down, great citation and great video. As someone who works at the boundary between neuroscience and AI, it is always a delight when KZread notifies me that you stroke again. Keep up the good work!

Thank you, Artem. That was an amazing explanation of how theta waves in the hippocampus help us remember things! The visual thought experiments were very helpful! There were so many aha moments in this. I once learned a memory trick from a memory expert that if you visualize walking through your house, and place things you want to remember in different parts of the house as you move through it, you'll be able to recall all of those facts/things. Now I think I understand why that is. Also, I have been traveling by car a lot lately, and listening to my textbooks as I stare out the window at the passing scenery, and have found that I comprehend what I'm listening to more easily than when I sit still and read it or listen to it. Considering that the Hippocampus is also involved in learning, this now makes sense as well. The brain and body are AMAZING and I hope to continue learning more about it from you along with my text books!

I'm studying towards being a neuroscientist one day and I'm currently taking trigonometry. I had never heard the word "theta" until this class started a few weeks ago. Your video gives me a super relevant reason for why I'm learning this stuff! Thanks for posting.

Thank you so much! It was indeed a tough choice what to include and what to leave out. One crucial thing I didn't include not to confuse a lot of people, is that theta rhythm is not a simple global wave, synchronized in the entire hippocampus. Instead, it is a travelling wave, which spreads along the septo-temporal axis of the hippocampus. Here's the link, if you are interested: www.nature.com/articles/nature08010 My main priority with these videos is to construct a comprehensive and holistic story, where all the pieces would be logically linked. It is sometimes very difficult, especially if papers contradict each other, or different authors provide different interpretations. So yeah, I often have additional material for each script, but it is sort of hanging and doesn't fit into the picture as nicely. But who knows, maybe some time later I'll do extended versions on these ;)

The discovery that the hippocampus (particularly CA1) has the circuitry to produce theta oscillations in the absence of septal input was in 2003 (Gillies et al.). These experiments were done in vitro. Later on, a modeling approach discovered the mechanisms giving rise to this intrinsically generated theta rhythm in CA1 (Rotstein et al., 2006)

@sethn896

Жыл бұрын

I’m sorry for this long comment, but your comment got me thinking and I had to put my thoughts somewhere… My humble guess is that the location at which the MS pacemaker neurons form their synapses on a given hippocampal dendritic tree is dynamic. perhaps, firing at a specific “time on the clock” is physically implemented by a spatial summation of EPSPs coming from both the MS pacemakers and the presynaptic cell, sufficient to trigger an action potential. In this sense, the temporal dynamics between one hippocampal neuron and the next is determined by the summation of the EPSP from the presynaptic hippocampal cell and “just the right” amount of an EPSP from the pacemaker cell to trigger an action potential. Where the MS pacemaker connects to the dendrite tree may depend on two things: the time of the theta rhythm that the neurons need to fire together, AND the physical distance away from the location of the hippocampal synapse that is sufficient for the triggering of an action potential given the “level/strength” of the EPSP corresponding to the desired time on the clock rhythm. That is, a lower frequency on the MS pacemaker cell is corresponding to a “lower point” on the theta rhythm, and a smaller EPSP is being generated-so, the location it connects to the dendritic tree on would be closer in distance to the synapse between the two hippocampal neurons than if there was a “stronger/higher frequency” of the clock rhythm, which would generate a larger EPSP, and would thereby be located further away on the dendritic tree to create a spatially-summed EPSP SUFFICIENTLY large enough to reach the threshold needed to trigger an action potential. Just an idea though

Great question! Relationship between music and brain waves is a very interesting and complex topic. There is a great amount of evidence, that listening to music with certain frequencies will entrain the rhythmic dynamics of neurons in the cortex (essentially amplifying the brain rhythm). The consequences of this on behaviour and cognitive processes are a bit less clear. In fact, one of the reasons we like the music, is because its sound structure resembles the neural oscillations, present in our brains from birth! Thank you for the suggestion!

Some studies suggest that handwriting activate synchronous theta waves, suggesting that handwriting is better suited for memorization and retention. Others feel that a single tool can not be isolated as the sole factor in theta wave synchronicity. Any thoughts on this spicy debate? Especially since you use (I believe) Obsidian like me....

Our perception of time changes as we grow older. Is it because of changes in the Hippocampus?

I remember reading an article stating that nitrous oxide raises theta wave activity significantly. I see why it's regarded as a disassociative if they have that much influence on memory.

Thanks for your work in public education of science. I'm a physicist turned systems engineer, who has recently make a pet study of neuroscience. I was wondering if you could clear some things up for me. At 1:09 you note γ as 30-80 Hz. (I know these are generalisations, and rythms are not only identified by frequency band) But some papers I've read include and analyse shortwave γ up to 200 Hz. I'm wondering why some (or most) papers cut it off at 80 Hz. From what I understand, even clinical amps, as apposed to research grade equipment, have response curve that is flat from (≤1)-100 Hz. So why 80? From what I understand (and correct me where I'm wrong), γ signals are inter-network resonant frequencies and arises localised when one part of a network loses some disinhibition from a neighbouring node. (It also, for reasons I don't understand, shows up during prediction failure?) So I am unsurprised that it has power at much higher frequencies, and find myself surprised when I see it upper-bounded. Granted, probably most of the power is in the 30 to 80 Hz band. But often, there is significance in subdleties represented in events and rhythms accounting for small fractions of the total power.

I'm having a little trouble imagining how neurons are responding to the phase of the rhythm when it's just transmitted as a scalar. Generally, higher amplitude in will result in either higher or lower amplitude out. How do you get a cell assembly to respond to a more or less exact amplitude? Could the waves be spatial as well as temporal? That would give a great population correlation to phase. If, for example, the theta wave only directly stimulated one edge of the assembly, or bands throughout, then propagated the wave locally, that might introduce a delay between populations in a specific order. That order would be consistently arranged by the phase of the theta wave. Furthermore, if the tissue has multiple phase-correlated populations, it might be able to "nest" sequences in their correlations. This would work the same way compression does in a computer; some bits represent a longer sequence, and each of those sequence elements could also represent a sequence. The benefit of such a symbolic representation would make the region considerably more powerful and general purpose, capable of storing arbitrarily complex ideas in one unified encoding. Just want to add that the hippocampus is required for eyeblink conditioning when there is a delay between stimuli, e.g. a beep, followed by a second or two of silence, followed by the shock or air puff. If there are assemblies responding to theta phase, how well would their period line up with the amount of delay that the hippocampus can handle, because after some maximum delay, the conditioned response disappears. It would be interesting if that delay corresponds to a 360° phase. Larger delays than the cycle period would map to poorly correlated phase.

if you have the theta sequences of thoughts , felling and space. could you send that via wifi if the frequency is the same to the hippocampus in the brain and will the brain decode and fire neurons from that code so you get an experience thought ,feeling etc.?

The enable pin of the brain, that's crazy

If I'm understanding correctly, both the mouse's trajectory across the place cell and the actual place of the mouse feed into the peak firing rate of the place cells. As the mouse walked through the corridor, would a graph of the firing of the place cell representing the halfway point of the corridor be a summation of the bell-shaped "place" component and the theta component - which would be a regular peak on a much smaller timescale that changed phase as the mouse passed through?

Do you have any information on "brain fog" specifically of the kind produced by COVID, apparently by mechanisms like neuroinflammation or microclots?

Really fascinating. so what's going on when you are tryng harad to remember something but you can't?

Is it possible that this Theta "pulse" is also being actively interpreted by some of the grid cells mentioned in the other video - the ones that can perceive abstract spatial differences along a 1 dimensional abstract axis? Is this how our understanding of the passage of time works?

The clock cycle is simply so that all the participating neurons are synchronized. If they weren't, they couldn't be computing anything, one neurons output would be unrelated in time to another's. The cycle guarantees that the same function is performed while they axons haven't changed. Same reason why you need a clock in a CPU, every circuit contributes to the result. The theta frequency would be determined by a tradeoff of how many neurons deep the signal can travel within one cycle (how complex a single 'piece' of memory can be) - recall that is super slow given chemical synapse transmission - and how fast you can access memory I'm guessing.

I think I will just repeat everyone's comments if I said you explain these concepts amazingly. But one question, how do you make these visuals and animations?
