Effort to Create Virtual Brain Begins

bryan8m writes "An IBM supercomputer running on 22.8 teraflops of processing power will be involved in an effort to create the first computer simulation of the entire human brain. From the article: 'The hope is that the virtual brain will help shed light on some aspects of human cognition, such as perception, memory and perhaps even consciousness.' It should also help us understand brain malfunctions and 'observe the electrical code our brains use to represent the world.'"

    All it takes to simulate a human brain is 22.8 teraflops? I thought I was smarter than that.

    Seriously, they expect it to take a decade to complete. By 2015, we could probably get processors with that kind of power from the local computer store. Then everyone could have their own virtual brain...wait, are they going to GPL this?

    So what happens if this thing develops a consciousness?

      As far as how much processing power is needed to simulate the brain, I've met quite a few people for whom a C64 and a tape drive would be more than sufficient... and maybe some duct tape.

      You are.

      According to the Business Week article this thing will be simulating about 10 thousand neurons. The human brain has about 100 billion neurons. This will be simulating a small section of cortex, not an entire brain. The goal seems to be to understand how cortical columns work, not to create a simulated mind. They actually will not even have enough "neurons" to match one human cortical column, but will probably still learn alot about the circuitry....

      You are wrong about neutrons. They are protons, that connect and interact to form intelligent thoughts.

      Neutrons are responsible for indifferent behaviour towards females. Recent study shows that slashdotters have enough neutrons emitted from their brain, that, they could be used as substitude of Californium 252.

      Hold your horses! There is abundant evidence that single neurons can perform more complex operations than a mere 'sigmoid fuunction'. That is a working approximation that can be useful from the point of view of simulations but that is all.

      Single neurons can potentially perform computations at the level of the of the passive cable equation. At the level of active membrane properties when added to those passive canle equation solutions. At the level of genetic instructions becoming activated in the nucleus and dendrites in response to activity. And finally the plasticity or learning rules that neurons use are not only computational very important but probably quite varied from brain region to region. Spike timing dependent plasticity for example allows the brain to pick out persistent correlations within highly noisy inputs. None of this is included in the impoverised neural-network viewpoint of 'sigmoids'

      The real question is why are they doing this? Markram is a top researcher and knows what he is doing. But i quesiton the motivations of big blue. i wouldnt be suprised if they didnt give two hoots about the science but rather are only doing this so that they can get the kind of publicity that posts on slashdot bring. Remember 'Deep Blue'? Lets hope they dont treat Markram like they did Kasparov

  2. Structure and Function by racecarj · · Score: 5, Interesting

    What's interesting about this type of study is the possible philosophical arguments that come up...

    Our brains are made of mostly water, carbon, etc.... which form neurons. This is only important in the sense that we are what we are because these neurons are able to take a set structure, where neurons interconnect, and then have a specific function, where they fire.

    There's nothing magical about these neurons. Let's say that you could replace these neurons with say, ultra-small marbles, that could take the same structure and perform the same function... It is logical to think that this marble-brain would be an actual brain, the same as any other. It would be a person.

    So if they're simulating a brain virtually, but this virtual construct simulates the structure and function correctly, would this virtual brain be aware? Would it be a "person"? I personally, would say that it would. But then, is it moral to ever shut such a simulation off (murder)? Or create it in a virtual world without any other virtual brains to talk to (torture)? Or create it at all for the use of an experiment?

    Is it a male or a female brain they're simulating?

    They work quite differently you know.
    Some even speculate that one of those two kinds of brain might need even less than 22.8 Teraflops to simulate.

  7. Wishful thinking by bloodredsun · · Score: 5, Insightful

    As someone who's spent many years as a neurophysiology researcher before becoming a programmer I feel I may have a bit more insight than the average person. What this project boils down to is a simplistic model of the simplist unit of operation of one area of the brain (neocortical column). Anyone who has followed research into areas such as epilepsy and memory will know of the massive gaps in our understanding of the realtionship of the brain and the mind. So this "first computer simulation of the entire human brain" is neither accurate in the sense that they are not simulating the human brain, nor are they the first to try what they are attempting. They only difference here is that they have the very public backing of a major corporation who understand the benefit of good publicity.

    This sort of research is fascinating and despetately needs to be done, but it does no one any favours when people associate tabloid style headlines to it. The days when we wear Richard Morgan style "stacks" are still as far away as ever unfortunately.

    A fun though struck me when reading the FAQ.

    Noone seem to have real contact with murray, and his adress was not really known. He also seem to have a little to much time on is hands, posting huge amounts of usenet posts etc. What if Murray did succeed a long time agoo, and is now letting his virtual brain (that somehow thinks it is murray) do all his spamming for him.

    Of course, this theory lacks in many points... :P
