  2. The future? by FosterSJC · · Score: 5, Insightful

    This can't really be the future of computing can it? I mean, we all are aware of the biggest difference between computers and thu human brain. Humans have great pattern recognition, while computers have great calculating/processing powers. Slicing pieces of brain and attaching them to chips hardly seems likely to enhance either the brain's computational ability or the chip's recognizing abilities. If anything, this is a step forward in facilitating communications between man and machine. I could see uses in reversing paralysis, but thought-upgrades or what have you are a long way off.

      You're being too literal here -- assuming that the end result will look just like a particular intermediate step. Nobody's saying we're going to build computers out of brain tissue. Well, maybe somebody is but that's not the point.

      In order to potentially imitate the human brain, we still need to learn a lot more about it. Since there's no manpage for the brain, it's a black-box problem and we have to reverse engineer it by trying various combinations of inputs and outputs (as well as analyzing the physical structure, of course). This new technique allows us to do so more effectively, hence improves our ability to understand. That's all.

      That's because it's not a breakthrough, it's commercialization of stuff that's been done in the academic labs for a couple years. Amazingly, it *does* take time to go from neat idea to marketable product. Electrode arrays can be a real bitch to fabricate.

      Plus, as the other poster mentioned, Jerry Pine's work. However, AFAIK, Pine's no longer working on that project, having found other interests. Pity, because the neurowells (as noted by Peter Fromherz in the New Scientist article) give the kind of single-unit interface that might be very desirable. I know that my group is planning to use similar approaches.

  15. For those who didn't read the article... by Kenrod · · Score: 2, Insightful



    The article is about medical applications, NOT computing. This doesn't have anything to do with computing. The researchers have found a way to keep larger portions of the brain alive so they can monitor the effects of psychoactive drugs. This may lead to new avenues of research for Alzheimers, Parkinsons, ALS, and many mental disorders. The chip is actually a tiny EEG. The first product is targeted to be an anti-anxiety drug.

    I think the most interesting aspect of this story is the living consciousness aspect. Can this piece of brain (or pieces intercommunicating) which is biologically active, become self-aware? Although these experiments have only been done on rats, if it were human brain tissue, would it be "alive" in an ethical, moral, or legal sense? These questions are probably several years away from being relevant, but is there any doubt we are heading down that road?

  16. Re:neurons and stuff? by Alik · · Score: 2

    Including all growth and electrical/chemical effects is not yet possible, because they are not yet all known. Furthermore, knowing all of them would probably tell us that there's no such thing as a generic neuron model; each cell has a very specialized gene expression profile that near-optimizes it for its role in the network. It may be that this can be reduced to expressing a neuron as a function of some hundred-odd parameters (as a guess), but it is not yet clear what the controlling parameters are.

    The MURG question of computational modeling of the human brain is a very open problem with no solution in sight. I was not familiar with them, but they do at least seem to be composed of people with useful technological skills. It'll be interesting to see if they come up with anything cool.
