Mouse Brain Simulated Via Computer

Mordok-DestroyerOfWo writes "Researchers from the IBM Almaden research lab and the University of Nevada have created a simulation of half a mouse brain on the BlueGene L supercomputer. 'Half a real mouse brain is thought to have about eight million neurons each one of which can have up to 8,000 synapses, or connections, with other nerve fibres. Modelling such a system, the trio wrote, puts "tremendous constraints on computation, communication and memory capacity of any computing platform."' Although there's more to creating a mind than setting up the infrastructure, does this mean that we may see a system for human mental storage within our lifetimes?"

    Unlikely, given that we are really no where close to even understanding completely everything about our complex brains.

    Do we even want to, wouldn't that take away some of the mystery behind humans. Afterall if we can figure ourselves out then doesn't that mean that we aren't really all that complex?

    wouldn't that also give us perfect explanations of people's actions making situations predictable violating free will?

    afterall if society is ultimately chaotic in terms of our understanding, then wouldn't this be the ultimate control?


    Don't be afraid to know more. It's coming if you want it or not. It doesn't mean a thing about free will: did you ever believe that your free will belong to your "ghost" or something? You are the sum of your parts and the interaction between them. Nothing scary about this.

    As for the "mental storage" - simulating a brain doesn't mean much about mental storage. Knowing and simulating an Intel chip in a program doesn't mean you can crack open an already produced Intel chip unit and hack few more cores in it.

    Plus, we already make very good use of tools to expand our mental storage: starting with notes, diaries, databases, computer knowledge systems, customer relationship programs, photos albums etc. etc.

    All these act as peripheral devices to our brain, and we should expect tighter integration between the brain and those (for example a wire projecting video directly in your cortex), but nothing that "expands" the brain structure at such a low level as is hinted in the summary.

    Without this you have a deterministic machine, and not a brain.
    Why do so many people refuse to entertain the possibility that they might be deterministic? Seems like people get overly defensive about their free will.

    However, there is an alternate theory of consciousness, based on quantum physics [quantumconsciousness.org]. It is inherently non-deterministic and cannot be modeled in a computer.

    I think the biggest argument against this is that synapses do not work on the atomic level. They are made of atoms, but quantum states do not seem to overtly affect organic matter at cellular level.

    Of course I could be wrong about this, but since decisions are usually the next best move it could simply be a matter of weighting what the "intelligence" applies to his rules as next best move.

    The problem with General Artificial Intelligence is that "the next best move" is often open ended and too many possible choices often give our current computation a run for its money unless its put into some form of predefined rules.

    The reason humans do so well is because we have certain criteria encouraging us to do things (hunger, pain, altruism, fear, etc etc)

    Hence, our general intelligence goals aren't that complex (usually... to feel good about oneself and one's life) and that our true intelligence is being able to recognize things that improve upon that given a set amount of rules we know.

    Which makes us very deterministic.

    Even rebelling against the crowd can often be very predictable in humans.

    We can have a brain that's fully deterministic at a microscopic level without doing away with free will, if we assume that our brains operate in non-linear conditions [wikipedia.org]. No, we can't. Chaos doesn't allow for a causal or non-deterministic effect of counsciousnes. It seimply means that the final state of the system cannot be predicted based on initial conditions, usually because these initial conditions can't be measured precisely enough. However, all the steps in the process are still completely deterministic. There is no more need or room for free will in a deterministic and chaotic brain than there is in complex meterological system. Or said another way, in which step in the nonlinear but completely deterministic chain of brain events does "free will" take place?
