Watching and listening to these kind of videos always bring me back to the fundamental question I ask myself - what the hell am I?!
I can't believe how clear and concise this talk was, especially since it involved the brain!. It was so elegantly spoken and he skillfully avoided talking psycho-babel which I think we all appreciate :)
Damn... My brain's just a jumble of equations?
I feel mortally insulted.
I can produce a super-computer that will smoke any supercomputer in production today... it takes me about 9 months to build it, and then about 18 years to train it.
when they crack the code i hope they install firewall
i dont want flash adverts projected into my dreams lol
This is one of the best TED talks. Great speech.
@Flem1337 I'm a 17 year old (a dumb one at that) and I could understand most of what he said. Of course, I did need to search up a bit to have a more thorough understanding of what he was talking about, but hey, we never stop learning.
In face, this video, along with Jill Bolte Taylor's TED talk enabled me to get a 96% on my English essay about truth, reality and perception!
I love learning about the brain, and this project excites me!
I actually looked this up by using my brain
that's 100 billion laptops
"it's blew a gasket"
Indeed. :) I wrote the same phrase earlier in this phrase and got it right. The typing fingers sometimes have a mind of their own; muscle memory, I guess. I have a real problem transposing 'think' and 'thing', do it all the time.
Really wish they'd discuss the actual equations they bring out in videos like this, I like having the math behind it explained.
Supercomputer can perform perfectly at Antarctica, Alaska, Greenland, Arctic, North Canada and North Russia.
Astounding. I hope we see this technology evolve into something very interesting.
The concept of being able to build a brain is both exciting and terrifying. I don't know if we'll have synthethic brains in 10 years but I might go pull Blade Runner off my dvd rack and give it a spin.
the theory he is presenting here around the 13-15 minute mark is just mind-blowing. i doubt many people listening to markram for the first time realize what he is actually saying though..
Looking forward to his holographic presentation in 9 years!
the electrical stimulation part around 13 minutes was incredible.
He didn't propose any new theory. That wasn't the point. He was filling us in on the progress of the research. Meet TED.
i haven't seen this video for a while now! BUT THIS IS AWESOME!!!! 8 years to go! lol
just a few tips to consider when you've got the brain mapped and symulated..
basically consider giving it extra regions. by which I mean, for example, create a region which is given information on the brain ie the information the reasearchers are lookng at. not all of it, but at least the map of neural activity. then connect that region with the visual cortex. The point being to allow the simulated consciousness to "see" how it's brain functions. That way, it can give direct feedback.
when they activated it, it began experiencing and thinking. Learning is provided by experience. the moment they showed it a flower, it started to think about the flower and in the process learned about the shape and colour, but since it's out of context (imagine complete sensory deprevation, then suddenly you see a flower) it's ability to "learn" is limited.
yeah, that's what happens when people recite and not research. i've made knowing and researching the sky and the universe my life, and plenty know more than me. it doesn't bother me when someone questions me or says i'm wrong, it motivates me to double check my theories and beliefs, and i usually learn something new..
@Udinbak cont. It could see which connections are active during a particular thought, it could refine it's thoguht processes, edvice on improvements, or refinements. It could ask to sever a synapse in order to reduce an unwanted response, strengthen it to increase a desireable response, even request a new synaptic pathway to connect and explore disparate functions/memories/senses/etc (synesthesia). If the new region could make these adjustments, then it would be able to do it automatically.
Once you build the circuit, how do you then model the dynamics of the morphology of the "circuitry" itself, that is, how the neurons re-wire themselves based on learning. If the circuitry is static, and the only dynamics are those of the circuit, namely, the cumulative firings between neurons, the brain is never really learning. Am I right? In other words, the brain architecture changes over time. How do you account for this?
This is very similar to Hierarchical Temporal Memory, and both of them are different implementations of Adaptive Resonance Theory.
These get better and better! Amazing what they are doing.
This video is on the net only 1 day and look at the amount of (different) reactions ... Amazing subject.!!!
I like this video a lot -
too actually be able to map out the processes, the coding, the hard-wiring of neuronal circuitry is amazing - I can't wait to see the results.
the reason the moon 'looks' or 'seems' larger when it's near the horizon is due to a lens magnification effect caused by the light from it traveling through a larger section of the earths atmosphere.
another cool exercise for your brain- when you see part of an object, but the majority is hidden out of your view, your brain can finish the object and represent it in your mind. i find this to be a very important clue to how the universe around us is represented.
Wow, that was awesome.. Also, the sentence "We can fire it up, and see what happens" is just so awesome :P
"That is kind a postulate that heart is just a pump, like so many others. You can hold on to it if you it gives you peace."
Are you saying the heart is NOT a pump?! I don't "hold on to it" because it gives me peace -- holding beliefs because they feel good is antithetical to science -- I hold that belief because it's a fact.
"Please allow me see science in context of humanity."
How could you not? Science was CREATED by humanity, the entire methodology is deeply rooted in our humanity.
This is really a great and commendable effort . It will help engineers built a living , evolving and adaptive hardware. Somthing like a standalone decision making machine . Well the flip side of it will more people of jobs .
This is quite interesting because I've read that, a brain can grow infinitely big with a relative amount of energy
You have to admit, artificial intelligence is a truly fascinating topic. If there's one thing I wish I could see before I die is for someone to build a "self aware" computer.
Imagine a fusion of Henry Markram simulation of the brain and Edward Witten's M T heory, wich includes 7 extra dimensions and there correspondence with our 3 D - time world. I wonder how the picture of the rose would 'reflect"in 11 dimensions.
I'm glad there are people out there with a more... optimistic attitude towards the things we have yet to explain;)
Ofcourse it'll be solved. You think people a million years from now will still have no clue? But it IS a tough one, and I agree very much that what he is talking about here, has very little to do with the actual "feeling" of being a human being. Though, as soon as we have build the model, it'll be alot easier to approach the following topics.
The reason why there was so little (there was some) bloodshed was the decision taken by the soviets mostly not to put their tanks on the streets. They knew full well that the U.S would not intervene if they did so but the leadership under Gorbachev chose not to.
That was pretty amazing to see ! 5 stars !
"It's just dogma of another kind."
What exactly is my dogma? I've not said that emotions are inherently bad, in fact I never even said they "make us believe 'stupid shit'"; words you carelessly or deliberately put in my mouth. But they CAN be dangerous, they CAN make us believe stupid or even dangerous shit, of not tempered by reason, if taken to be a reliable measure of objective reality.
Hmmm...there are some interesting consequences of the points that have been raised here pertaining to mental equilibrium.
I would use an analogy that nearly all psychotropic drugs (especially SSRI's) are tantamount to being nothing more than blunt instruments, like using a chain saw for brain surgery, conversely entheogens that attenuate essential neurotransmitters such as Serotonin or dopamine can be likened to being a precision "scalpel" like tool.
Way way cool.......
Seeing as these simulations are run on computers, and thus are completely and understandably deterministic, any simulation you run on it can be perfectly recreated at any time.
Besides, I highly doubt that they are going to get anywhere near what we would recognize as consciousness in anything like the time table he laid down.
And, as we can see, Raymond Kurzweil was right: the Singularity is near !
@leostoltoy
If the universe is around 15 billion years old, than it took it around 11 billion years to create the first brain. Which also goes together with what he says later, that the universe has evolved a brain to see itself. Also reminds one of Carl Sagan: "We are the way the cosmos can know itself"
@Udinbak cont2. The region would have to be passive at first in order to train the new brain to understand the sensory experience, then active control gradually increased while the mind becomes accustomed to making self adjustments. safety protocols in place of course. active and passive control at the early phases would be counter productive, since the young mind would exploratorially make potentially damaging alterations which could render the mind insane. or the equivalent.. just a thought..
one computer equals one neuron but linking 10,000 computers or a million computers for that matter together will always give it a finite number of thought that is possible. A brain or one neuron for that matter is not finite but holds the possiblity to think infinitly. A person can and have thought of impossible things thoughout history, therefore the brain has the capacity to be infinite. That is something that computers can never do, is to think infinitively.
I don't know.. I can only comment on where I have been living for the last 30 yrs (UsA) it seems people got along with each other better in the 70 early 80s than they do today. A LOT better. These days it seems people are full of rage for some reason.. I don't know why..
@Udinbak I agree. Smell and taste is (just) chemical impulses. We have detectors that can identify chemicals/smells. But the blue brain will be the only machine to experience it as we do.
@Udinbak cont3. the study of creating new regions in order to process information in new ways (like a region that analyses visual input and computes precise distances, velocities, mass, angles, weight, etc. or one that can interpret hmtl and has access to the internet) will be invaluable when you (the future) get round to addnig functionality to the human brain.virtualising a new region and integrating it into an unaltered human brain will be the key to transhuman consciousness.
I agree, but it is hard to remain as open as most people when you are an "intellectual" free thinker, because one's subject of intellect often requires that person to dedicate a majority of his life to master the subject objectively. As a result, it would be expected for that person to be quite reserved to his theories.
Yes, it is possible to remain still open despite that. It takes a great person. And that's a lifelong journey, irrespective of intellect.
A very facsinating talk, even if it's all theoretical. Though, it's nice to see that people are putting the effort into trying to figure out how to build a brain. I would love to see how these guys progress over the next decade.
Such is the stable equilibrium.
I agree. So the craft of appliance by powerhouses could be called a tool of evolution?
Right, but the point of what he was saying with all the perception stuff was that you only believe you can think infinitely. If you have a single neuron and you stimulate it, all it can know or think is either "yes" or "no".
Through millions of these networked together a more complicated "infinity" emerges. There is no magic in your brain. If it can think of infinity, then there is a reason for it, and that reason can be measured / understood / reproduced.
They should have done a presentation on rolex watch. now thats high tech!
As long as we continue our exponential progress in science, it seems very certain that this will eventually be solved considering how far we came from just the last century. Thing is, the final answer to this question might seem completely different or ever more complex than what we previously postulated.
Also the major flaw in AI - is that computers dont have emotions. All our buying and concerning styles etc are driven by emotions. When a computer goes to a shop all they see is: best colour, most intense smell, cheapest, coldest, lightest etc. Imagine your shopping basket if u got a computer to buy ur groceries or clothes!
1/2 He said ( H. Markram ), that 99.9% of what we " perceive" is not actually what we see. Which manifests how fast at the nano scale the brain is working, even before the eyes have seen the actual object, the mind is already infering and comong up with perceptions which can be verified by the eye. All of which happens in a split second. I remember when MIchio kaku was asked, " is the human brain a nano computer?, Michio answered no in a subtle way. What H. Markram is building, the blue brain .
It will be interesting to follow this experiment and see how far they get. I wouldn't think it takes an entire 'laptop' to simulate a neuron since neurons run much slower than computers, but who am I to say ;) I'm sure sentience is way way off though.
We always create to fill a need, with great variation on the definition of 'need'. There's no reason a sufficiently large and well-trained neural network or other brain simulation could not do the same.
Ethics and free will will be the questions.
There are many good things that can come from this, but the seduction of illegally controlling another that someone else has decided needs "fix" will be a big issue that will need to addressed.
As children, many of us were read fairy-tale stories like the man living in the belly of a fish for several days. As adults, we know that such a thing is a fairy-tale... Oh wait, some adults still believe THAT fairy tale.
Very inspiring talk.
When we approach such possibilities with sincerity, the results are a celebration of life.
Just ten years away from when things realllly get moving...
You can always create a consciousness that WANTS to be snuffed out.
Not hard to speculate.
From 10,000 neurons to 10 Million in 10 years by 'law' of computational cost.
From 10 Million to. 100 Million by using simpler vector processors rather than that horse of a machine they have now.
100 Million to 1 Billion by improvements in software.
1 Billion+ through budget increases, which can be expected if the structure shows adaptability and learning.
Using a functional rather than biological model would also vastly increase neuron count.
big bang - "one day there was nothing, then it went boom"
I am in LOVE with SCIENCE!!!!
Please examine the species that have evolved in the last 100 years since we have been studying them.
The perceptual bubble? Maybe it is because our brain cannot identify how far away the moon is with the two slightly different angles that our eyes capture.
the brain may be constructed, however the "observer" cannot.
the brain is just a processor that translates in this case visual information (light) coming through the senses (eye) into pulses as shown. It is not the brain that sees, it is "you" (some call it consciousness, soul) the observer that see and understand its reality. it is the same observer that consciously decides to make a certain decision (move one finger and not the other for no reason)
Fascinating. If we are confined in a bubble or territorial space known as the universe and it provides at the extreme human possible extension of his potential, then it it could be seen as a deliberate design for "milking" / nursery / isolation virtual room for potentialities. In the layman's term if we keep on zooming neurons, we would be looking at a quantum representation of ourselves. Perhaps that is how we are created.. just a hypothesis among many other possibilities,
As live4Cha said in a response to me, regarding a factual claim I made, "You can hold on to it if you it gives you peace." As if beliefs should be dictated not by the facts, but by what makes you feel good. This, sadly, is overwhelming true for the vast majority of human beings, even for the most objective among us.
he says a neuron per laptop, if i'm not mistaken. And 10,000 per neo-cortical-column
Actually, we can already create viruses from scratch, and we can almost create bacteria from scratch (we still rely upon having a phospholipid membrane to insert genetic material into for the bacteria - or at least last I checked).
thanks ted, ive been waiting months to hear this talk.
thanks.
I as a normal child went to church because mommy and daddy wanted me to, however when I reached the age of 10 I got saved and started going because I wanted to. I am the perfect example for religious indoctrination.
My old religion may have shaped a bit of me, but that is merely a small portion of who I am. I cannot know what I would be like if i hadn't grown up religious, but I'm pretty sure I wouldn't be much different.
We indeed create reality. There is no way this complexity just happened by chance. What is amazing is that these neurons firing look just like the map of the universe itself. Is the universe then, self aware?
woww this is what ive been waiting for from Ted!!
It makes perfect sense if you don't intend on being mystical. The 'projection' is just the brain's comprehension of the world, which is translated to motor output, which produces new input and further 'projections' ad infinitum. So yes, it's infinite in a sense, much like any other piece of non-halting computer software or other information processes for that matter, until it is forced into conclusion through an external force of nature.
"Please take you anger to someone else... You are a aggressive person. Period."
Please take your anger to someone else... You are a very passive-aggressive person. Period.
According to Moore's Law, the average supercomputer in 10 years should be about as powerful as a human mind and the average desktop computer in 20.
"What is about emotions? Love hate? joy fortune? What about our heart? What is the knowledge without love?"
Love, hate, joy, etc. are seated in the brain. If your heart fails and we replace it's function with a machine, are you no longer able to feel? Of course not. Don't take something which is metaphorical literally: the seat of emotion is the brain. Replicate the functions of your neurons perfectly in some other hardware, and we replicate you, emotions and all, including love.
That's great! At least you have some sort of unseen sense of fashion.
Wikipedia is wrong on that point. Look it up some more. I am wrong as well, it's not because of the atmosphere either. It's true that their angular diameter is actually a bit smaller when the moon is near the horizon. There is, however, no consensus as to why the moon appears larger on the horizon, and the theory that it's because it's compared to the foreground has been discredited many times. So Wikipedia and this guy are wrong. Since I'm not giving a TED talk, it's less important that I am.
The problem is that success would be moral peril.
You can't simply create a consciousness and then snuff it out to debug it. How cruel.
"It took the universe 11 billion years to build a brain". But Earth is only 4.5 billion years old, and life 3.5 billion years old. "The human brain is still evolving at an enormous speed" - I think this is a nonsensical phrase in terms of evolutionary theory. Everything living is evolving at all times, but unless we can point to a very large change in the rate of either death or reproduction influenced by different kinds of brain, we can't predict whether the brain is evolving significant change
The world of Science and Consciousness are coming together. His great studies will revolutionize the world. This Presentation, as you view it, is one of the links that directs and propels my studies into a higher level of thought. Thank you, Dr. Angel De Jesus
very interesting presentation .... even the advertisement is interesting lol
I don't think that's possible. The brain is about as compact as an intelligent consciousness can be, any "super-consciousness" would require a tremendous amount of physical space.
Any gamer would say their game is more than a game. In poker reading the opponent just happens to be the game (cards matter less). I objected to the analogy because in poker you only have to deal with a few variables when in politics you aren't dealing with only a table full of people at any given time.
Lots of very powerful nations have met their end in history but lets hope we are getting better at finding other solutions than power play.
@neymoura But we don't. There is only a tiny, very short period in the evolution period of a conscious being during which the being is occupied with emulation of living creatures. Our road towards pecfection is very long, and we are almost in the beginning. In a matter of few centuries or millenia humanity will evolve to a certain level, when that happens we won't be occupying our lifes with such things.
As children, many of us were read fairy-tale stories like the kiss of the Princess changing a frog into a Prince. As adults we know that such a thing is a fairy-tale, yet if we replace the kiss of a Princess with BILLIONS of years of chance and random processes, natural selection with nature red in tooth and claw and somehow these processes have magically transformed frogs into modern man ! It certainly takes greater faith to believe in such fairy-tales than that....In the beginning, God created
@neverthat79 Fair point. I took his use of the word "evolving" in the sense of darwinian evolution, but if he simply meant "It's taken 11 billion years for brains to appear in the Universe" and "brains continued to change rapidly" then that's fair and I take back my comment!
Science is awesome !!!
@Hsapienslaptopicus I don't know whether you meant that as an oblique insult, but I love HHGTTG!
Also, at the risk of losing all my credibility, I'll clarify: I meant to say "neurobiology"**. I frequently type one in place of the other. I know...I'm an idiot.
So this says our brain is a universe itself. So what if our universe is a brain itself? What if we are all part of a universal brain, our solar system, our galaxy are a part of a brain of a higher being that we don't know of, because we can't sense it. Think about it, can a cell of a neuron know that it's actually a part of a sophisticated organ, a brain? I think this is interesting.
And there are only about 10 billion neurons. And given Moore's law, you might see enough computing power to actually put his ideas in practice. Although, I agree that the conference was pretty unprofessional overall.
A deeply fascinating & most Intriguing subject....
Many people forget that belief in god is not necessarily belief in religion. Religion, at least when taken is full, is doctrine - though it often contains lessons that are worth considering (considering being the key word as opposed to blind acceptance). Belief in god though is based on many factors, tangible and intangible. Many brilliant people believe in god - but many also don't.
life creates life.
