I was never satisfied with their explanation for why they had to start with the human brain rather than the brain of a MUCH simpler organism like C. elegans.
Re:Why the Human Brain Project Went Wrong and How to Fix It by Animats on Sunday September 27, 2015 @03:38PM (#10287664)
Exactly. OpenWorm [1] is trying to do exactly that, emulate C. elegans, with all of 302 neurons. It doesn't work yet, but they;'re plugging along. When that problem is totally solved, and the neural model is working right, it's time to move up in complexity. Probably to lizards or birds.

About two decades ago, I heard Rod Brooks talking about building a human brain. He'd done some good artificial insects and was big on purely reactive AI. At the time, he was promoting Cog [2], as a way to get to human-level AI in one big jump. I asked "You've done an insect brain. Why not try to get to a mouse brain next?". He replied "I don't want to go down in history as the man who created the world's greatest robot mouse." 20 years later, Brooks doesn't even have mouse-level AI, although he does have a robotic vacuum cleaner company.

A mouse has about 1g of brain mass; a human has about 1000g. But they're both mammals, with about 90% similar DNA. If someone could simulate a mouse at the neural simulation level, that would be real progress. Once you have a mouse simulation, human level is a scaling problem.

The Human Brain Project blew through a billion dollars in funding while OpenWorm is a volunteer effort. That's the real problem.

It's not clear at all that Mouse->Human is simply a scaling problem.

It would appear that there is some emergent phenomenon (consciousness) somewhere on the scale between mouse and human. This phenomenon may be triggered by a surplus of "computational resource" with respect to "body to be controlled", which I personally think is unlikely. It may be triggered by a matching of computational resource to controllable complexity, i.e. the hands and fingers -> tool use, who knows?

There is so much we don't know about cognition. For example, are Whales/Dolphins self aware/conscious? They have the requisite brain mass, if it's simply a scaling problem.

What makes you so sure mice aren't conscious? Insects probably are not, I have no strong opinion on mice, but dolphins almost definitely are.
Re:Why the Human Brain Project Went Wrong and How to Fix It by steve19 on Sunday September 27, 2015 @10:39PM (#10288685)
Do you believe mice ask themselves "why do I exist?" or whether it is better "to be, or not to be"?

I am genuinely interested in your perspective.

I adore my dog. He shows a wide range of what I believe to be genuine emotions. But I do not think he is self-aware, and by self-aware I mean able to contemplate his own existence (and therefor lack of existence). For that matter, I don't think he ever contemplates the lack of my existence (despite feeling it when I am not around, so I am told).

Re:Why the Human Brain Project Went Wrong and How to Fix It by danschuller on Monday September 28, 2015 @12:18AM (#10288894)
I think conscious isn't a binary yes/no kind of property. It's more a range, where you can put humans arbitrarily at 1.0 and then a mouse might be 0.05 or something like that. It certainly has self-awareness of somekind, even basic biological homeostasis requires self-awareness of a limited kind.

Other animals then present more consciousness, like chimps, dolphins, elephants etc and would place somewhere between the mouse and humans.

Thought experiment: Dogs tend to act guilty when they know they've done something wrong. If you get two dogs together, and one does something naughty, do both act guilty afterwards or only one? If only one, then is it not reasonable to assume that the guilty dog has internally models the situation as "I did bad thing, I am bad dog" but the other dog internally models the situation as "I didn't do bad thing, I am good dog"?

I'm not saying dogs sit around quoting Kant, but they're highly social animals and I find it hard to believe they don't have some internal representation of themselves.

Re:Why the Human Brain Project Went Wrong and How to Fix It by nerdo on Monday September 28, 2015 @01:51AM (#10289095)
Dogs act guilty in response to being scolded, not because they know they've done something wrong.
Re:Why the Human Brain Project Went Wrong and How to Fix It by PhasmaFelis on Monday September 28, 2015 @03:28AM (#10289269)
No, we could always tell when my dog had gotten into something even before we found the evidence, because she'd be slinking around embodying the word "hangdog" from the moment we walked in the door. There's debate over whether this is actually guilt or simply anticipation of punishment, but there's no question that dogs know when they've done something they weren't supposed to do.

Reminds me of the Vonnegut quote from Cat's Cradle:

“Tiger got to hunt, bird got to fly; Man got to sit and wonder 'why, why, why?' Tiger got to sleep, bird got to land; Man got to tell himself he understand.”

What would observe differently about your dog if he were self-aware? Self-awareness wouldn't automatically let dogs speak their minds or write philosophical treatises on existence. When a dog is just sitting still, I have no idea if they're being self-reflective or not.
Re:Why the Human Brain Project Went Wrong and How to Fix It by steve19 on Monday September 28, 2015 @01:09AM (#10289005)
Good question.

I would expect him to exhibit less reliably to stimuli. His behaviour is closer to a large switch(stimulus){} statement than the emergent behavior of human reaction to situations and stimuli.

One example: he was stepped on when a small puppy by a very old man from that point on and to this day, many years later, he has a major dislike of old people that he does not know well.

If the same thing happened to a child, I would expect the child to slowly, over time, question why they disliked all other old people when the old people they do know are kind to them. This would result in a change of behavior without someone explicitly teaching them.

Re:Why the Human Brain Project Went Wrong and How to Fix It by TheOtherHobbes on Monday September 28, 2015 @05:50AM (#10289599)
Human reactions are hardly freeform. Most human responses are either instinctive or socially scripted/learned - more often, some combination of the two.

The only thing that makes humans truly unique is the fact that we can store, retrieve, and process information outside our bodies. While we can question our responses, as in your example, we don't - unless we live in a social environment that suggests we should. (Not all environments do. Some actively discourage it.)

Everything else we do - solving puzzles, counting, acting socially, teaching in person, showing emotions - appears in simple forms in at least some other animals.

Going up a level, humans are actually an extremely large, planet-spanning colony organism with very limited collective consciousness. We act more like an aimless flock of birds or mound-building insects than a collective with awareness of its own planetary situation.

Re:Why the Human Brain Project Went Wrong and How to Fix It by marvy on Wednesday September 30, 2015 @10:55PM (#10308948)
I think the case for a collective consciousness for humanity is much too weak. An insect colony does way better. At least most individual insects tend to act toward the common good, rather than waging war on other insects in the same colony.

No way, I did not mean to imply I thought that mice do that. But I think that's setting the bar too high. How often does the average person ask themselves such questions after all? I think four year olds are conscious, and yet I doubt that they ask such questions either, and might even look at you funny if you asked them such a question.
Re:Why the Human Brain Project Went Wrong and How to Fix It by greatthanks on Monday September 28, 2015 @12:13PM (#10291180)
some people (very young children or mentally handicapped humans) don't ask those questions either.

furthermore there is a reason why in Buddhism this intellectual thinking and questioning is considered unessential to being.

Humans have 92% DNA commonality with mice, and 98% commonality with chimpanzees. There's a lot of handwaving about how special humans are, but it's not showing up at the genetic level.
Re:Why the Human Brain Project Went Wrong and How to Fix It by Frondo on Sunday September 27, 2015 @07:28PM (#10288286)
I'm curious--did the Human Brain Project ever produce any noteworthy science, or did it actually blow through a billion bucks with nothing to show? Because, as far as I'm concerned, if we got a billion dollars worth of science out of it, who cares if they hit the mark? That could still be a lot of good science!
Re:Why the Human Brain Project Went Wrong and How to Fix It by lern_too_spel on Sunday September 27, 2015 @11:48PM (#10288826)
GP is incorrect. HBP has only blown through 200 million dollars. It is planned to blow through a billion Euros over the course of a decade.
Re:Why the Human Brain Project Went Wrong and How to Fix It by themgt on Sunday September 27, 2015 @02:59PM (#10287505)
Exactly. So much of neuroscience is still in "unknown unknown" phase, and the idea of just doing this massive interdisciplinary project to simulate a full human brain, built on the pile of sand that is any sort of "theory" of full-brain simulation ... it's like dedicating $1 billion to some dude's unpublished idea of proving P = NP. Bullshit should have been called before this ever got off the drawing board.

Sure seems like the EU has it's fair share of incompetent technocrats if you can throw $1 billion at some nonsense any handful of PhDs in the field could have told you was nonsense if you'd just picked up a phone.

> any handful of PhDs in the field could have told you was nonsense

The problem with groundbreaking work is often that any handful of experts can tell you that it's nonsense. E.g., look at the reception that Barry Marshall got when he proposed that stomach ulcers were caused by bacterial infection. [1] All the experts "knew" it was caused by "stress, spicy foods, and too much acid" in the stomach. Eventually he got the Nobel prize, but you have to wonder what else we're missing out because whoever discovered it wasn't as dogged or as lucky as Marshall.

Examples of this type are not a good guideline for policy decisions, almost by definition. For every Marshall, there's a million cranks whose ideas are rejected by the establishment and rightfully so. At the outset, all these ideas appear equally wild. But resources are scarce -- we can't just fund everything.

So what to do with a billion Euros? Obviously, we shouldn't put everything in a single pot. Particularly not in one crazy pot. That's why people complain about Markram's ego trip and enabling politicians. If you got a certain amount of funding, diversify: fund a couple of cranks, sure, but 90% should go toward what's often called normal science where small steps add up to comparatively predictable progress.

(In Markram's/the HBP's defence: Ultimately, the project will yield a metric tonne of normal science, especially in terms of infrastructure etc. However, everybody will be disappointed at the end...)

Re:Why the Human Brain Project Went Wrong and How to Fix It by wpietri on Monday September 28, 2015 @10:51AM (#10290731)
I think examples like Marshall can't be the only guideline for policy. But they are excellent examples for policy. Marshall made lives better for millions of people.

Anybody responsible for science funding should be keenly aware that the machine they steer is much better at responding to obvious failures like Markram than silent failures that ulcer treatment was for decades.

Re:Why the Human Brain Project Went Wrong and How to Fix It by Houshalter on Sunday September 27, 2015 @07:03PM (#10288234)
Because it's unlikely that C. elegans can't even learn. It doesn't have any brain structures equivalent to ones in humans. It's neurons work totally differently. They are so different from us that anything we learn probably wouldn't apply to human brains. A more intelligent animal, ideally a mammal, would be a much better choice.

Yes, quite true, but in this thread, a bunch of people who know nothing at all about neuroscience and cognitive science - worse, who don't believe anyone anywhere knows anything about those subjects - are going to pontificate on why having a bunch of trained experts study the brain was always a terrible idea.
Re:Why the Human Brain Project Went Wrong and How to Fix It by foobarian on Sunday September 27, 2015 @10:34PM (#10288676)
The thing I was always wondering about brain simulations is how to determine what level of detail is enough. What if neurons evolved to take advantage of some funny quantum phenomena that we may not even know about yet, and without this the simulation won't work? For this reason I would think that getting a simple brain simulation to work would at least help enumerate the physics most involved in their function.

Now maybe there is some extra physics that comes into play at scale (like some quantum-computery effect with human-size brains that induces conciousness) but maybe this would be detectable as small discrepancies in the small simulations (especially as they progress in size to e.g. mice).

Re:Why the Human Brain Project Went Wrong and How to Fix It by sanxiyn on Monday September 28, 2015 @01:44AM (#10289074)
Since brain has to work in a noisy environment, it is unlikely its function depends too much on details. Neurons can't depend on effects we don't know about, because if effect is large, we would know about it, and if effect is small, brain has to work with noise that size, so it is not necessary for us to get it right for its function. (It's a different matter for its exact output, but that's for later.)
Re:Why the Human Brain Project Went Wrong and How to Fix It by dhj on Monday September 28, 2015 @10:19AM (#10290567)
You don't need to appeal to "quantum effect" to think that being able to understand, well enough to simulate, THE SIMPLEST NEURAL SYSTEM of any organism would be helpful before jumping in feet first with 1 billion euros into the most complex neural system. Of course it is a process over 10 years and they have "only" spent 200 million so far. I would expect that quite a bit of that money is going to study model organisms from c. elegans to mouse to chimpanzee. Studying simpler model organisms is one of the best ways we have to understand fundamental biological principles.
Re:Why the Human Brain Project Went Wrong and How to Fix It by orbifold on Monday September 28, 2015 @04:39AM (#10289438)
If there would be such a quantum effect it would contradict a lot of conventional theoretical physics, brains operate at high temperatures ~310 Kelvin, and the length scales involved are fairly large for quantum mechanics. You would only expect to see quantum effects at such large length scales at very low temperatures, because otherwise the correlation length is just too small.
Re:Why the Human Brain Project Went Wrong and How to Fix It by streptomycin on Monday September 28, 2015 @06:17PM (#10293586)
My line of thinking is, say it'll cost X to model C. elegans.

For even the simplest mammals (let alone humans), surely the cost is >> X. So might it be a decent idea to give it a shot with C. elegans first? Because if we fail with C. elegans, we're almost guaranteed to fail with a mammal. And it's not immediately clear to me that we currently have the ability to do it successfully even for C. elegans.

I am definitely not a neuroscientist so maybe I am misguided. I'm also not wedded to C. elegans as being the ideal prototype, and I doubt anyone is (except possibly the people already studying C. elegans). But the first attempt should definitely be on something as simple as possible.
