I experienced a TBI in 2017, losing my identity and conscious access to memory. I was already neuroatypical and had seizures, but my capacity for 'linear communication' was often confounded. I knew words and understood when people spoke and could respond, but it became easier to write in symbols with a few terms peppered in for clarification. But i basically 'mapped out' my brain's rewiring process in real-time, and there's so much overlap in concepts and terminology--using the computer memory framework as a reference has helped me streamline my understanding and troubleshoot ongoing problems with my memory. Thanks for uploading such great and detailed information--it's been really helpful!
Very impressive recovery story Ingrid! I have had the good fortune of working with many people recovering from TBIs. Their recovery continues strongly for more than a decade… I hope this note finds you continuing on your journey! No two TBIs are the same, but…. Chances are… you have great memories still awaiting to be discovered. The harder you work at memory recall…. The more memories get re-connected! An impressive non-linearly rate of recovery… TBI 2011 😃
you come across as hypochondriac and presenting with some kind of personality disorder, perhaps narcissism, that I'm not qualified to speculate about, more so than someone that actually has brain damage.
For a long time I've had the idea that these system (neural computers and AI) will need some sort of random generator in the loop. Was amazed to hear that some of these systems actually use it. Just my gut feeling that true intelligence has to have some form of randomness in it, for it to produce novel new ideas and solutions to problems.
I designed a neuromorphic processor back in 2004 when I was at The Neurosciences Institute. I could write a book on the neuromorphic paths one could take and the reasons they won't work. You did an excellent job of covering the different areas of the brain that need to be represented in a circuit. There are two aspects of neural computation that are paramount in creating brain-like functionality, but always get glossed over. They are synaptic plasticity and connectivity. Almost all of the changes in your brain that affect behavior are centered on the efficacy of synaptic propagation, likewise a lot of the functional differences between areas that have similar neuronal structure are the result of the connectivity within and between neural areas. The memristor is going nowhere - it's a red herring. If someone is successful in creating a commercially viable neuromorphic chip, they will encounter two problems that will stop them cold: 1) no one is trained to use them, as the computation is fundamentally different in everyway from a traditional computer; 2) intelligence is extremely complicated, not from an intellectual perspective, but from a conceptual perspective. The effort and education required to be able to use this type of chip and also make the conceptual leap to create an intelligent system is beyond anything available today..
would you agree that there might be research to do on something like a universal language of logic first? Let me explain. Right now, we have machine "language" at the center, the "ones and zeroes" everyone should know about, with several layers designed to make sense to humans - assembly first, low-level programming languages second, and finally high-level ones and scripts. What we do here is take computer logic and make it human-readable. I'd think it may come at a cost. I'd be inclined to say we may tackle the problem wrong right now. Don't get me wrong, the research is all valuable - there's lessons to be learned from all the attempts so far which will no doubt help down the road. But as so often in human nature, especially when I look at the tedium at office jobs, you get to ask: How do we even know what of all of this is truly neccessary? Is there something we overlook? What's the core problem, and did I communicate it correctly? Most times you can't even be sure, because our wirings are not even uniform. At work. Now try globally. Human cultures, male and female, go down to animals etc. One might do good in finding the Atom first, before we dive into how to do alchemy. "Intelligence" as it stands is fairly human-centric in its definition, or in plain terms we wouldn't know it if it bashed our face in right now because the term is quite old and refers to all kinds of clever outcomes. Stuff like "emotional intelligence" is a buzzword, but it's inference itself may lead us to the core of the problem here. Right now we all have a fuzzy interpretation of what kinds of machines we want to build with this. Maybe it's time to define the problem first?
@@ddlc_monika the problem that we are trying to solve is one intuitively known by everyone: we are trying to build a god. At its core, I think that the race for AI (including the need for better hardware for AI models) is about designing an entity that can solve all of our problems, an intelligent entity inspired by human intelligence but not bound by the limitations of the human condition (i.e being limited in ressources such as time, attention, biological needs, ...), a true embodiment of the philosophical notion of Logos.
There is a universal language of logic, it's called 'First Order Predicate Calculus' or FOPC. i think I understand what you are saying. If you are saying that we don't even have a good definition of intelligence - I agree with you. People use the words artificial intelligence to describe everything that doesn't have a straight linear relationship or has a unique response to a stimulus. The point I was trying to make about the conceptual complexity of intelligence is itself complex. People that haven't lived in the world of neural computation can't see it - they think it is just like neural nets. In truth neuromorphic is to neural networks like neural networks are to Von Neuman architecture. They may look similar but they are fundamentally different. @@ddlc_monika
Most people I've worked with have more modest asperations than becoming the spirt of the universe. Our goal was always discovery, of the mind and the brain and the mind/brain. I don't think anyone expects the intelligence clergy to come and bless their work. Few realize, as I discovered during my R&D work, that the test for intelligent systems isn't deterministic it is behavioral.@@Hollowed2wiz
1) llms can translate natural language into any code. Tranformers where made for translations. 2) Artificial intelligence nowdays is an emergent property of neural networks, it is not hard-coded symbolically.
ran across a paper that tried to determine how complicated an artificial neural network would be needed just to simulate one neuron is about 5 to 8 layers - easy to find: A temporally convolutional DNN with five to eight layers was required to capture the I/O mapping of a realistic model of a layer 5 cortical pyramidal cell (L5PC).
That was a TCN the layers equate to temporal context....the 5-8 layers simply represent the time windown needed to recognise a spike train. so not indicative of complexity. There are better approches which are more faithful to postsynaptic neuronal response which are quite small and efficient compared to the TCNN approach
@@RaverSnowLep It's a common mistake, while editing the voice lines, you might hear the start of a sentence, and to not lose time, you skip to the end of the sentence, so you might incorrectly assume that that line is correct because the start is correct and the end is correct. You'll not notice it repeats itself because you haven't heard the middle. The only way to avoid this is to hear the whole thing, which almost no one does. I think I remember hearing an Oblivion NPC in like 2006 saying something like "let me do that one again" between two identical sentences, you can find it on CZcams.
The lesson to take home is really that we have no great theory for why the brain works as it does, and thus we are guessing when we try to replicate it in hardware or software.
Sounds like we have a lot of the how's and I think we understand a lot of the why's. Trying to replicate it is helping to connect those dots. If anything it is deconstructing the longstanding theories that made it seem like magic.
In fact, everything is not as bad as it might seem. People understand a key concept of how the brain works - it is a huge set of nested conditions, which, due to their large nesting, can make an incredible number of matches (speaking as an AI student). The main thing that still remains a mystery is the details of the structure of the brain and the principles of its self-learning. This certainly does not indicate an almost complete lack of knowledge about the functioning of the brain; I would even say that the opposite statement is more accurate. We know more key concepts than we have left to learn.
This is very evident when you read about medications for depression and bipolar …. They all state, “while how the drugs works is unknown it’s suspected that …”
I imagine in the future neuromorphic and Von Neumann architecture will work side-by-side, the former for adaptability and robustness, and the latter for precision and fast math

The brain isn't an analog device. It's a biological machine, something we have never even tried before. Describing it as analog or digital is fundamentally wrong. I don't know of a single machine that works on chemical signals, based completely upon water, is self replicating and self repairing, and have a hard age limit coded into them. Oddly enough, we went more and more electricity based with our technological innovation, while biological evolution did the complete opposite.
I think the brain is so efficient due to its size and nature of cells. Nerve cells are eessentialy small batteries, holding electrical potential and discharging it when told to do so by either primary or secondary neurotransmitters. And in this case the brain can be way more sophisticated, as each nerve cell much doesn't act as a logic gate, but rather only fires when sufficient or the right type of data is pass to it, only then will it fire. It basically acts as an impossibly complex neutral network, only we don't have any neural network technology I am aware of that can run on as little energy as the brain. We have transistors smaller than cells, but each cell also holds a bunch of data of the whole machine(DNA), and also depends on it metabolism, it's life span, etc... Basically a single cell acts a a mini-brain, being specialized in what it does but also having all the data in what everything does. I feel like the reason it's hard to figure out how neural networks solve a problem is the same reason it's so hard to study the brain. Each bit of information passed onto the brain is already spread across dozens of trillions of cells.
Thinking about it. Brains are complex, according to the brain. In reality it's quite simple but grand. Like how a single neuron may have so many connections that are rather simple in function but are so vast that it seems difficult to comprehend where to even start or how to even start. Recently they essentially made synthetic neurons "learn" to play pong, it's simply just a game of slowly reverse engineering how some aspects of the brain function and how this works in tandem with other functions. It's not a question of "if" but when. I say 50 years.
Brain might only take low watts most of the time, but it's been on, running, consistently for our entire lives. I think that's where consciousness emerges, and the first AGI will probably be lost with the speed we force it to learn, while creating the giant LLM matrices.
Amazing! I am a TMS Patient you should look into this technology. It's MRI Strength Magnet that goes on my right side of my head and had honestly saved my life. Want to work on a book on my experience.
This is insanely interesting, knowing that this much was tried by big names in the hardware industry, makes you think what might be going on with their RnD departments nowadays
Thanks for the great view, as always, on the subject. In electronics academia we talk only about this and to be fair im kinda tired, but your opinions are very refreshing
I remember reading about memristors in an ieee magazine back around 2010, I was a freshman taking intro ee classes. Even back then neural nets got a lot of attention and the article talked about how memristors could be used with neural nets, I remember thinking this was going to be huge, and then nothing for a decade. Cool to see it mentioned now in 2024. The future can come fast or it can come slow, but there's no stopping its arrival. What a time to be alive.
Your description on how the brain processes data reminds me of OpenCog's Atomspace. That uses a mixture of different structures joined together in various ways to both represent knowledge and process data. It is a metagraph based system, where the brain (don't quote me on this) seems like a graph based system. It's weird to see a line of similarity between those two things.
I don't think we know enough about the brain yet to understand if the non-digital aspects are needed to replicate it's power (probably needed if we want to literally simulate a human brain but that's not really the goal).
@@azhuransmx126 And even what they know is a drop in the ocean. The issue is that our tech is fundamentally different from how our body functions. It's like comparing a fish to a whale. Both live in water, but they couldn't be any more different.

@VanFire87 The area of the brain responsible for controlling offspring rearing in mammals is known as the limbic system, and within this system, the anterior cingulate cortex (ACC) plays an important role in regulating maternal behaviors. The ACC is located in the medial part of the frontal lobe and is connected to other areas of the limbic system, such as the hippocampus and amygdala. This brain area is involved in the regulation of emotions, decision making and evaluation of social stimuli, and its activity is believed to be essential for maternal motivation and care of offspring. In studies in mice, it has been shown that lesion or inactivation of the ACC can decrease maternal motivation and reduce the mother's response to signals from her offspring. The ablation of the ACC by electroscalpel makes the mother regress to a stage 200 million years more primitive or reptilian, seen in animals from the Carboniferous period 440 million years ago, mammals are from the (Permian Triassic) 230 million years ago. Scan that area, compile and digitize the algorithms that make it work, calibrate its neuronal weights, download the cortical model of the mother on an artificial substrate descended from current GPUs (probably photonic chips), reconnect its inputs and outputs and you will see how the mother returns to take care of her babies as if nothing had happened. Turn off the artificial neural network and the mother will revert to a reptilian state and her babies will starve to death. In the future General Artificial Intelligences will do a brain scan of animals in Biology starting from the most primitive beings (flatworms descended from Pycaia) to the most advanced (apes and humans). With these stored connectomes, a virtual twin of the biological being will be created that will be subjected to the same gradient, amplitude and frequency of inputs and if they react exactly the same (Intelligence) we will have created a digital twin. In the digital world copy and original lose all meaning, once something becomes Code and becomes Information it can be replicated millions of times and no one can say that they have the original download of a song. We have been digitizing everything, books, audio, paintings, etc., and the last thing we are going to be able to digitize is going to be the most important thing, our brain and not even we will achieve it, but the AIs will achieve it. Ray Kurzweil describes a similar procedure to realize the Mind Uploading in his book.
Memory bottleneck is more serious problem than moore's law, a senior dev in my team once wrote a small C code to show how memory bandwidth limited modern CPUs are, the code would just read serially from an array of 1 Billion 4 Byte integers and time it with elements parsed per ms, on testing even a single ZEN 2 core would saturate 40GB/s dual-channel 3200 DDR4, let alone 8 cores, its almost magic how CPUs and GPUs can still work so fast being so bandwidth starved, specially on servers.
Good explanation of the differences. Using a digital approach we can only simulate a finite number of neurons. Hardly comparable to a brain. Perhaps the analog nature of Quantum computers might get closer, but they will be limited to even a smaller number of neurons. I think the current limit of qbits is less than 200.
Take a look at Susan McKinstry's work on moving away from von neumann architecture, its pretty cool and is another road for this type of work. She's a professor at penn state and has videos online of her research.
The Von Neumann bottleneck is not the reason why neural computing is popular. It is pretty easy to make hardware not based on that model. It is because neurons take several deep learning layers to simulate just what we know about neurons ability to communicate, and we still know very little.
You answered the question in the video. The brain is only capable of achieving that low of a power consumption due to it making mistakes. Computers take very high amounts of power, but they are deterministic
Most of the current AIs i assume simmulate by machine learning and neural network principles to some extant how a brain works. In our own brains, there is no need for a simulation as the rules of the game are hardwired through physiognomy, chemical neurotransmitter and neuro elictricity ... physics chemistry biology brain. Not just like having different levels, but having different levels interacting with one other or multiple other levels in parallel. I would further assume, aslong the hardware stays just in silicon, there will always be a simulation aspect to it and thereby less energy efficiency as that efficiency comes from the varied interations between different levels of the brain. Am i mistaken?
Yes. There is no reason why silicon couldn't imitate or even surpass the performance of a biological neuron. A biological neuron calculates on the order of hundreds of impulses per second. A digital neuron, if built as an ASIC on cutting edge process node, could calculate on the order of _billions_ of impulses per second. The overwhelming majority of the complexity in a biological neuron is not necessary for the computing the neuron does, so you could really argue that there is a simulation aspect to our brain. Enormous quantities of molecules and proteins that have nothing to do with the logical operations, as opposed to a chip where only the substrate is not an active participant in calculation. At best they have immunological or other physical resilience purposes that an artificial brain wouldn't need to implement.
Neural networks don't actually simulate how a brain works, since a human brain is not trying to approximate a mathematical function, which is all a neural network is doing. An analogy would be an aeroplane; the aeroplane manages to fly, but it is not using even remotely the same mechanisms for flight as a bird does. The end result is similar, yes, and its designers were probably originally inspired by birds, but the way it is actually achieved could not be more different.
“Simulate” has been the implicit problem with AI. Just because you can argue that your CNN or AlexNet, whatever, appears to be accounting for, say, 70% of what you attribute to be a brain’s network response(e.g. the initial retinal network of a mouse), this does not mean your AI network is actually doing anything like the brain network - in fact you’re making assumptions on both ends - what the mouse network actually is, and your AI approach. This difficulty was already in full swing with Newell and Simon’s General Problem Solver, 1972, where they assumed that because the program’s steps were, say, 70% similar to the steps humans claimed to take in solving something like a symbolic logic proof, that this meant their simulation approach had validity, that it was actually near emulating the human brain/thought process - when nothing such was necessarily the case.
That digital neuron could be a bit better by using DRAM instead of SRAM. Speed is obviously not needed, and DRAM use 8 times less space on the silicon than SRAM. The problem is that you need to keep refreshing it as its essentially a tiny capacitor.
This reminds me of Pluto, where one of the roboticists, says that to create the “perfect” robot (the most like a human) you need to introduce chaos to its mind by flooding it with countless different personalities and strong emotions and let it bring order to the chaos, this may or may not end up creating a robot that is a monstrous psychopath but it will result in a robot most like a human for good or bad.
A company is using 100 lava lamps to introduce chaos for using in cryptography. Maybe we need to create a tiny chip with 100 micro lava lamps to create a particular personality, making it impossible to predict their actions. It always was a problem in computing science, how to generate random numbers from nothing.
another aspect that makes computer can't be powerful like human brain is the human itself. Human brain doesn't care about size, like it can grow to whatever size if necessary, while the chip manufacturers and perhaps customers prefer smaller CPU form factor. I wonder what can we achieve if we make a chip with the same volume as human brains
Oh that's a neat extrapolation of sci-fi at the end. the Mullet joke? no. That was bad. I got a good flash of a cool Cybernetic Sci-Fi setting where instead of humans with cybernetic impacts, it's robots with memristor or IBM true-north type stuff to make them random more similar to biological life.
This really helps explain intel’s pivot towards NPUs for me thank you for making the vid. Like of course AI is the current trend but this really helps show how it can be more than just a trend.
We do not know how memories are stored or how the brain computes. We know synapsis have something to do with them we can destroy the synapses and the memory trace remains (Tomas Ryans work and also mentioned by Randy Gallistal).
nice video. Repeats 2x @13:55: "and lastly the brain is an analog device, digital devices are an ill fit for replicating their behavior so we need to incorporate the analog element, which limits the systems flexibility"
The truth is because researchers have not manage to implement quantum pathways into hardware. Random chaos? Check out the recent discovery that quantum mechanism is found to be key in photosynthesis. This area of research to make brain like circuits requires quantum biology
I wonder, as neuromorphic computing develops what would software be like? If memory and computation can be combined, could the line between software and hardware also be blurred? In the brain, is there a difference between the substrate and its program?
Making brain computers is quite easy. Its called having a child. Aka a new brain cooperation partner. Costs extremely little too. So little it was even possible tens of thousands of years ago.
@@rizizum Costs almost nothing to train. Mimics by itself. In fact the most successful schooling systems are mainly powered by children interacting with each other, like the ACT system. Very automated and very scalable when done properly.

Not all white papers are legit… I looked at the 1971 memristor white paper and it seems like it’s reaching for greatness like it wants to be first to coin the term, in case someone else comes up with a working system. At the time integrated circuits and microprocessors were brand new cutting edge stuff. We had the naive opinion that the human brain could be replicated as AI (Hal) with this (new for the time) technologies. This paper though interesting historically seems to be more about publishing papers as a requirement to maintain academic status than pushing the state of the art forward. I could be horribly wrong but after 52 years nothing came of it. Not even by the Soviets or China. Yeah, I was around then…🤣
I don't think a computer like this will be created anytime soon, not just because of the difficulty, but because the main motivation is to create a replacement for specialized labor.
If neuromorphic hardware were to be built in solid-state-chips, could they mimic neurons ability to grow, die, multiply, and morph their shape? How important are these aspects for the brains ability to compute?

But i basically 'mapped out' my brain's rewiring process in real-time, and there's so much overlap in concepts and terminology--using the computer memory framework as a reference has helped me streamline my understanding and troubleshoot ongoing problems with my memory.
Thanks for uploading such great and detailed information--it's been really helpful!

Very impressive recovery story Ingrid!
I have had the good fortune of working with many people recovering from TBIs.
Their recovery continues strongly for more than a decade…
I hope this note finds you continuing on your journey!
No two TBIs are the same, but…. Chances are… you have great memories still awaiting to be discovered. The harder you work at memory recall…. The more memories get re-connected! An impressive non-linearly rate of recovery…

you come across as hypochondriac and presenting with some kind of personality disorder, perhaps narcissism, that I'm not qualified to speculate about, more so than someone that actually has brain damage.
Thats cool
For a long time I've had the idea that these system (neural computers and AI) will need some sort of random generator in the loop. Was amazed to hear that some of these systems actually use it.
Just my gut feeling that true intelligence has to have some form of randomness in it, for it to produce novel new ideas and solutions to problems.
Isn't that exactly how diffusion works in image AI?
@@user-up1id5rv2m yes, I think it does
Not randomness but chaos. If you think that idea is interesting, then you should definitely look into cybernetics.
I designed a neuromorphic processor back in 2004 when I was at The Neurosciences Institute. I could write a book on the neuromorphic paths one could take and the reasons they won't work. You did an excellent job of covering the different areas of the brain that need to be represented in a circuit. There are two aspects of neural computation that are paramount in creating brain-like functionality, but always get glossed over. They are synaptic plasticity and connectivity. Almost all of the changes in your brain that affect behavior are centered on the efficacy of synaptic propagation, likewise a lot of the functional differences between areas that have similar neuronal structure are the result of the connectivity within and between neural areas. The memristor is going nowhere - it's a red herring. If someone is successful in creating a commercially viable neuromorphic chip, they will encounter two problems that will stop them cold: 1) no one is trained to use them, as the computation is fundamentally different in everyway from a traditional computer; 2) intelligence is extremely complicated, not from an intellectual perspective, but from a conceptual perspective. The effort and education required to be able to use this type of chip and also make the conceptual leap to create an intelligent system is beyond anything available today..
would you agree that there might be research to do on something like a universal language of logic first? Let me explain.
Right now, we have machine "language" at the center, the "ones and zeroes" everyone should know about, with several layers designed to make sense to humans - assembly first, low-level programming languages second, and finally high-level ones and scripts. What we do here is take computer logic and make it human-readable.
I'd think it may come at a cost.
I'd be inclined to say we may tackle the problem wrong right now. Don't get me wrong, the research is all valuable - there's lessons to be learned from all the attempts so far which will no doubt help down the road.
But as so often in human nature, especially when I look at the tedium at office jobs, you get to ask: How do we even know what of all of this is truly neccessary? Is there something we overlook? What's the core problem, and did I communicate it correctly? Most times you can't even be sure, because our wirings are not even uniform. At work.
Now try globally. Human cultures, male and female, go down to animals etc.
One might do good in finding the Atom first, before we dive into how to do alchemy. "Intelligence" as it stands is fairly human-centric in its definition, or in plain terms we wouldn't know it if it bashed our face in right now because the term is quite old and refers to all kinds of clever outcomes. Stuff like "emotional intelligence" is a buzzword, but it's inference itself may lead us to the core of the problem here.
Right now we all have a fuzzy interpretation of what kinds of machines we want to build with this. Maybe it's time to define the problem first?
@@ddlc_monika the problem that we are trying to solve is one intuitively known by everyone: we are trying to build a god. At its core, I think that the race for AI (including the need for better hardware for AI models) is about designing an entity that can solve all of our problems, an intelligent entity inspired by human intelligence but not bound by the limitations of the human condition (i.e being limited in ressources such as time, attention, biological needs, ...), a true embodiment of the philosophical notion of Logos.
There is a universal language of logic, it's called 'First Order Predicate Calculus' or FOPC. i think I understand what you are saying. If you are saying that we don't even have a good definition of intelligence - I agree with you. People use the words artificial intelligence to describe everything that doesn't have a straight linear relationship or has a unique response to a stimulus. The point I was trying to make about the conceptual complexity of intelligence is itself complex. People that haven't lived in the world of neural computation can't see it - they think it is just like neural nets. In truth neuromorphic is to neural networks like neural networks are to Von Neuman architecture. They may look similar but they are fundamentally different. @@ddlc_monika
Most people I've worked with have more modest asperations than becoming the spirt of the universe. Our goal was always discovery, of the mind and the brain and the mind/brain. I don't think anyone expects the intelligence clergy to come and bless their work. Few realize, as I discovered during my R&D work, that the test for intelligent systems isn't deterministic it is behavioral.@@Hollowed2wiz
1) llms can translate natural language into any code. Tranformers where made for translations. 2) Artificial intelligence nowdays is an emergent property of neural networks, it is not hard-coded symbolically.
ran across a paper that tried to determine how complicated an artificial neural network would be needed just to simulate one neuron is about 5 to 8 layers - easy to find: A temporally convolutional DNN with five to eight layers was required to capture the I/O mapping of a realistic model of a layer 5 cortical pyramidal cell (L5PC).
That was a TCN the layers equate to temporal context....the 5-8 layers simply represent the time windown needed to recognise a spike train. so not indicative of complexity. There are better approches which are more faithful to postsynaptic neuronal response which are quite small and efficient compared to the TCNN approach
13:57 repeating voice line.
Im seeing this so often in videos now, whats going on?
@@RaverSnowLep An AI bug? :)
@@RaverSnowLep It's a common mistake, while editing the voice lines, you might hear the start of a sentence, and to not lose time, you skip to the end of the sentence, so you might incorrectly assume that that line is correct because the start is correct and the end is correct. You'll not notice it repeats itself because you haven't heard the middle.
The only way to avoid this is to hear the whole thing, which almost no one does. I think I remember hearing an Oblivion NPC in like 2006 saying something like "let me do that one again" between two identical sentences, you can find it on CZcams.

You turned A.I for a moment 🤖 😁
Mullet computing is the future!
Would that elevate the status of North American hockey players? Or bass tournament anglers in The South? Asking for a friend.... 😉✌️
The lesson to take home is really that we have no great theory for why the brain works as it does, and thus we are guessing when we try to replicate it in hardware or software.
Sounds like we have a lot of the how's and I think we understand a lot of the why's. Trying to replicate it is helping to connect those dots. If anything it is deconstructing the longstanding theories that made it seem like magic.
In fact, everything is not as bad as it might seem. People understand a key concept of how the brain works - it is a huge set of nested conditions, which, due to their large nesting, can make an incredible number of matches (speaking as an AI student). The main thing that still remains a mystery is the details of the structure of the brain and the principles of its self-learning. This certainly does not indicate an almost complete lack of knowledge about the functioning of the brain; I would even say that the opposite statement is more accurate. We know more key concepts than we have left to learn.
@@lit1041indeed, the only real issue left is the memory/storage problem. Where woo tends to happen 😂
@@lit1041 I'd say the main mystery is figuring out how subjectivity works, and we haven't made any real progress on that.
This is very evident when you read about medications for depression and bipolar …. They all state, “while how the drugs works is unknown it’s suspected that …”
I imagine in the future neuromorphic and Von Neumann architecture will work side-by-side, the former for adaptability and robustness, and the latter for precision and fast math
That what current AI are, just not of hardware but software shape

"Lastly, the brain is an analog device"
No, because the video mentioned that part twice in immediate succession 🤣
The brain isn't an analog device. It's a biological machine, something we have never even tried before. Describing it as analog or digital is fundamentally wrong. I don't know of a single machine that works on chemical signals, based completely upon water, is self replicating and self repairing, and have a hard age limit coded into them. Oddly enough, we went more and more electricity based with our technological innovation, while biological evolution did the complete opposite.
Incredibly compelling video. Learned a lot. Thanks as always
I think the brain is so efficient due to its size and nature of cells. Nerve cells are eessentialy small batteries, holding electrical potential and discharging it when told to do so by either primary or secondary neurotransmitters. And in this case the brain can be way more sophisticated, as each nerve cell much doesn't act as a logic gate, but rather only fires when sufficient or the right type of data is pass to it, only then will it fire. It basically acts as an impossibly complex neutral network, only we don't have any neural network technology I am aware of that can run on as little energy as the brain.
We have transistors smaller than cells, but each cell also holds a bunch of data of the whole machine(DNA), and also depends on it metabolism, it's life span, etc... Basically a single cell acts a a mini-brain, being specialized in what it does but also having all the data in what everything does. I feel like the reason it's hard to figure out how neural networks solve a problem is the same reason it's so hard to study the brain. Each bit of information passed onto the brain is already spread across dozens of trillions of cells.
The quality of your videos is outstanding, man.
That mullet joke? Chef's kiss XD
Repeats on 14:20
Thinking about it. Brains are complex, according to the brain. In reality it's quite simple but grand. Like how a single neuron may have so many connections that are rather simple in function but are so vast that it seems difficult to comprehend where to even start or how to even start. Recently they essentially made synthetic neurons "learn" to play pong, it's simply just a game of slowly reverse engineering how some aspects of the brain function and how this works in tandem with other functions. It's not a question of "if" but when. I say 50 years.
Most likely the brain is nothing more than a transceiver.
Brain might only take low watts most of the time, but it's been on, running, consistently for our entire lives. I think that's where consciousness emerges, and the first AGI will probably be lost with the speed we force it to learn, while creating the giant LLM matrices.
Hahaha never heard someone compare computers and the mullet. You are on another level. Bravo
Amazing! I am a TMS Patient you should look into this technology. It's MRI Strength Magnet that goes on my right side of my head and had honestly saved my life. Want to work on a book on my experience.
This is insanely interesting, knowing that this much was tried by big names in the hardware industry, makes you think what might be going on with their RnD departments nowadays
Thanks for the great view, as always, on the subject. In electronics academia we talk only about this and to be fair im kinda tired, but your opinions are very refreshing
I remember reading about memristors in an ieee magazine back around 2010, I was a freshman taking intro ee classes. Even back then neural nets got a lot of attention and the article talked about how memristors could be used with neural nets, I remember thinking this was going to be huge, and then nothing for a decade. Cool to see it mentioned now in 2024. The future can come fast or it can come slow, but there's no stopping its arrival. What a time to be alive.
14:42 its the shirt for me
"The work goes on"
Powerful
Your description on how the brain processes data reminds me of OpenCog's Atomspace.
That uses a mixture of different structures joined together in various ways to both represent knowledge and process data. It is a metagraph based system, where the brain (don't quote me on this) seems like a graph based system.
It's weird to see a line of similarity between those two things.
at 14:11 it seems you rendered the same scene twice
This was a very nice video, thanks :)
I was NOT prepared for the mullet similie!!
I don't think we know enough about the brain yet to understand if the non-digital aspects are needed to replicate it's power (probably needed if we want to literally simulate a human brain but that's not really the goal).
You of course don't know, but there are people out there that knows much much much more than you.
@@azhuransmx126 And even what they know is a drop in the ocean. The issue is that our tech is fundamentally different from how our body functions. It's like comparing a fish to a whale. Both live in water, but they couldn't be any more different.
@@VanFire87 aircrafts and birds, they don't need to work the same, to do..... the same and better.
@@azhuransmx126 We are fine the way we're going forward right now, with a few feature inspired from our nervous system and the like. Advancement in processing power and efficiency is our way forward, and not making a human brain computer, unless you're willing to overturn and overhaul all of the advancement we have gone though and don't forget the massive numbers of human experiments required.
@VanFire87 The area of the brain responsible for controlling offspring rearing in mammals is known as the limbic system, and within this system, the anterior cingulate cortex (ACC) plays an important role in regulating maternal behaviors. The ACC is located in the medial part of the frontal lobe and is connected to other areas of the limbic system, such as the hippocampus and amygdala. This brain area is involved in the regulation of emotions, decision making and evaluation of social stimuli, and its activity is believed to be essential for maternal motivation and care of offspring. In studies in mice, it has been shown that lesion or inactivation of the ACC can decrease maternal motivation and reduce the mother's response to signals from her offspring.
The ablation of the ACC by electroscalpel makes the mother regress to a stage 200 million years more primitive or reptilian, seen in animals from the Carboniferous period 440 million years ago, mammals are from the (Permian Triassic) 230 million years ago. Scan that area, compile and digitize the algorithms that make it work, calibrate its neuronal weights, download the cortical model of the mother on an artificial substrate descended from current GPUs (probably photonic chips), reconnect its inputs and outputs and you will see how the mother returns to take care of her babies as if nothing had happened. Turn off the artificial neural network and the mother will revert to a reptilian state and her babies will starve to death. In the future General Artificial Intelligences will do a brain scan of animals in Biology starting from the most primitive beings (flatworms descended from Pycaia) to the most advanced (apes and humans). With these stored connectomes, a virtual twin of the biological being will be created that will be subjected to the same gradient, amplitude and frequency of inputs and if they react exactly the same (Intelligence) we will have created a digital twin. In the digital world copy and original lose all meaning, once something becomes Code and becomes Information it can be replicated millions of times and no one can say that they have the original download of a song. We have been digitizing everything, books, audio, paintings, etc., and the last thing we are going to be able to digitize is going to be the most important thing, our brain and not even we will achieve it, but the AIs will achieve it. Ray Kurzweil describes a similar procedure to realize the Mind Uploading in his book.
Excellent explanation, great video. This is why I subbed.
Memory bottleneck is more serious problem than moore's law, a senior dev in my team once wrote a small C code to show how memory bandwidth limited modern CPUs are, the code would just read serially from an array of 1 Billion 4 Byte integers and time it with elements parsed per ms, on testing even a single ZEN 2 core would saturate 40GB/s dual-channel 3200 DDR4, let alone 8 cores, its almost magic how CPUs and GPUs can still work so fast being so bandwidth starved, specially on servers.
like a mullet hahaha. Thanks for making informative videos. I missed a few recent ones and I'm just now going through them
Good explanation of the differences. Using a digital approach we can only simulate a finite number of neurons. Hardly comparable to a brain. Perhaps the analog nature of Quantum computers might get closer, but they will be limited to even a smaller number of neurons. I think the current limit of qbits is less than 200.
Very interesting and good video. Would also love to watch video about bio-computers...
The most important thing is to continue learning and updating existing methods
The vocal delivery is so serious and then theres a joke that throws me off
Take a look at Susan McKinstry's work on moving away from von neumann architecture, its pretty cool and is another road for this type of work. She's a professor at penn state and has videos online of her research.
The Von Neumann bottleneck is not the reason why neural computing is popular. It is pretty easy to make hardware not based on that model. It is because neurons take several deep learning layers to simulate just what we know about neurons ability to communicate, and we still know very little.
The mullet joke at the end was priceless. It was the delivery. 🙂🖖🏻
Business in the front, party in the back.
Mullet joke got me :'))
Oh could you mabe do a video on the future of analog computing?
Anywa, love you video's.
video on analog computing would be dope
You answered the question in the video.
The brain is only capable of achieving that low of a power consumption due to it making mistakes.
Computers take very high amounts of power, but they are deterministic
Most of the current AIs i assume simmulate by machine learning and neural network principles to some extant how a brain works. In our own brains, there is no need for a simulation as the rules of the game are hardwired through physiognomy, chemical neurotransmitter and neuro elictricity ... physics chemistry biology brain. Not just like having different levels, but having different levels interacting with one other or multiple other levels in parallel.
I would further assume, aslong the hardware stays just in silicon, there will always be a simulation aspect to it and thereby less energy efficiency as that efficiency comes from the varied interations between different levels of the brain. Am i mistaken?
Yes. There is no reason why silicon couldn't imitate or even surpass the performance of a biological neuron. A biological neuron calculates on the order of hundreds of impulses per second. A digital neuron, if built as an ASIC on cutting edge process node, could calculate on the order of _billions_ of impulses per second. The overwhelming majority of the complexity in a biological neuron is not necessary for the computing the neuron does, so you could really argue that there is a simulation aspect to our brain. Enormous quantities of molecules and proteins that have nothing to do with the logical operations, as opposed to a chip where only the substrate is not an active participant in calculation. At best they have immunological or other physical resilience purposes that an artificial brain wouldn't need to implement.
@@cerebralmand yet, the brain needs over 3300 types of neurons.
Neural networks don't actually simulate how a brain works, since a human brain is not trying to approximate a mathematical function, which is all a neural network is doing. An analogy would be an aeroplane; the aeroplane manages to fly, but it is not using even remotely the same mechanisms for flight as a bird does. The end result is similar, yes, and its designers were probably originally inspired by birds, but the way it is actually achieved could not be more different.
“Simulate” has been the implicit problem with AI. Just because you can argue that your CNN or AlexNet, whatever, appears to be accounting for, say, 70% of what you attribute to be a brain’s network response(e.g. the initial retinal network of a mouse), this does not mean your AI network is actually doing anything like the brain network - in fact you’re making assumptions on both ends - what the mouse network actually is, and your AI approach. This difficulty was already in full swing with Newell and Simon’s General Problem Solver, 1972, where they assumed that because the program’s steps were, say, 70% similar to the steps humans claimed to take in solving something like a symbolic logic proof, that this meant their simulation approach had validity, that it was actually near emulating the human brain/thought process - when nothing such was necessarily the case.
Thank you for this video. Very educational.
That digital neuron could be a bit better by using DRAM instead of SRAM.
Speed is obviously not needed, and DRAM use 8 times less space on the silicon than SRAM.
The problem is that you need to keep refreshing it as its essentially a tiny capacitor.
From an application perspective, would've been worth mentioning Event Cameras as well.
This reminds me of Pluto, where one of the roboticists, says that to create the “perfect” robot (the most like a human) you need to introduce chaos to its mind by flooding it with countless different personalities and strong emotions and let it bring order to the chaos, this may or may not end up creating a robot that is a monstrous psychopath but it will result in a robot most like a human for good or bad.
A company is using 100 lava lamps to introduce chaos for using in cryptography. Maybe we need to create a tiny chip with 100 micro lava lamps to create a particular personality, making it impossible to predict their actions. It always was a problem in computing science, how to generate random numbers from nothing.

"Best of both worlds, like a mullet." Well done
another aspect that makes computer can't be powerful like human brain is the human itself. Human brain doesn't care about size, like it can grow to whatever size if necessary, while the chip manufacturers and perhaps customers prefer smaller CPU form factor. I wonder what can we achieve if we make a chip with the same volume as human brains
Oh that's a neat extrapolation of sci-fi at the end. the Mullet joke? no. That was bad.
I got a good flash of a cool Cybernetic Sci-Fi setting where instead of humans with cybernetic impacts, it's robots with memristor or IBM true-north type stuff to make them random more similar to biological life.
Maybe that feeling when you hit your funny bone is your clock nerve shorting to the muscle activation nerve! Perhaps we have a global clock line!
This really helps explain intel’s pivot towards NPUs for me thank you for making the vid. Like of course AI is the current trend but this really helps show how it can be more than just a trend.
Gotta get me one of them mullet cuts.
Now.
We do not know how memories are stored or how the brain computes. We know synapsis have something to do with them we can destroy the synapses and the memory trace remains (Tomas Ryans work and also mentioned by Randy Gallistal).

Really great content!
I wonder, as neuromorphic computing develops what would software be like? If memory and computation can be combined, could the line between software and hardware also be blurred? In the brain, is there a difference between the substrate and its program?
Probably, you are just going to use some different python libs for that :-D. Compiler developers will care about the rest.
Making brain computers is quite easy.

Not all white papers are legit…
I looked at the 1971 memristor white paper and it seems like it’s reaching for greatness like it wants to
be first to coin the term, in case someone else comes up with a working system.
At the time integrated circuits and microprocessors were brand new cutting edge stuff.
We had the naive opinion that the human brain could be replicated as AI (Hal) with this (new for the time) technologies.
This paper though interesting historically seems to be more about publishing papers as a requirement to maintain academic status than pushing the state of the art forward.
