destinyland writes "A Stanford researcher has spliced light-sensitive algae genes into human brain cells to fire neurons when activated by a laser. Light is shined through an implanted fiber optic cable (blue light on, yellow light off), and the procedure can target very specific deep brain structures too fragile for most surgery. 'Once the researcher attaches the other end of the cable to a laser, he or she has absolute and flawless control over that group of neurons.' Science writer Quinn Norton cites it as a first attempt at 'building useful handles on the very things that make us ourselves.'"

  • Why brain cells.... (Score:3, Informative)

    This sounds an awful like binary.... Could this potentially be used to make bio-computers? Or at the very least Bio-Memory? Perhaps it has too many flaws to be useful, but the idea of using cells to store data is interesting to say the least.
    • So, how do they get the laser beam through the person's thick skull to shine on these light sensitive cells?

        they need to open up the brain to insert the virus and it seems they install a 50 micrometer fiber optic cable that points to the specific cells right after that. and my best guess is that you have a cable coming out of your head which you then connect to the laser. the whole thing sounds pretty amazing with the whole algae and archaeon genes, very cool.

      Like with all drugs that activate the nucleus accumbens, you'd develop tolerance. Soon even the largest laser doses wouldn't suffice, and you'd become a laser addict, roaming the streets, rummaging through trash containers, trying to find old CD drives to get your laser fix. Is that really the kind of life you want for yourself?
      • Yea, coherent light would become a controlled substance. Wicked Lasers would be contraband. Laser junkies would be hanging around the NIF, begging for spare photons. It wouldn't be pretty.

        So, thanks for the foresight. I'll have them run a copper wire alongside my fiber, just in case.

    I have this mental image of a bunch of soldiers with sets of remotely controlled optical fibers hanging out of their head. For some reason in this image they're all kind of grey like something out of Edward Scissorhands or perhaps The Matrix, or maybe The Borg from Startrek....and the best bit is that the guy controlling them is doing it with an r/c aircraft radio. "Crush, kill, destroy, my pets!". Wait, I think someone has implanted MY brain with Hollywood crap. They did it the old fashioned way though - tv brainwashing.

    • It'd probably be cheaper to just build Killbots, and people would complain less too. Not to mention better armored.

      And the twist at the end is that the guy with the r/c controller is really a robot!

      • Bah, you missed that last 5 minutes where you find out the guy is real and the R/C controller is actually controlling HIM!

      If it was made by microsoft, right after that command they all would start stomping the life out of your pets....

    Things you need to do with your DNI:

    1. Invoke mental imagery, preferably without interfering with normal vision.
    2. Infer mental imagery manipulation.. for example, when you hear the question "what letter do you get by turning a Z on its side?" results in a common specific quale of visual intelligence.
    3. Test and improve the rate and bandwidth.

    With such an interface you can do human computer interaction in ways that are completely unavailable to current input devices. Imagine having a 3d modeling tool where you can just think about the object you want, or how it differs from the object you're seeing. Imagine, if you can, receiving data at a higher bandwidth than video.

    • Even if a neural interface were only able to replace my mouse and keyboard (or multiple ones), I'd be happy. No need to worry about ergonomic "layout"s, no repetetive stresses. I'd love to see that, even if it's a ways off still.

    Sci-fi has been having human "jacking in" to computer systems, via direct connection to the brain for a while. This technology ought to make that possible, Just how to make the brain cells actually connect themselves in some useful way to the rest of the brain, seems tricky though, and i hope these gene splice brain cells are safe against cancer etc.

    I wonder if this can be applied to other purposes like bypassing damaged sections of a paraplegics spinal cord.

    We would need to develop a neuron to laser device at the other end first, but the possibilities of making people walk again are worth investment.

  • Before Michael Crichton got in bed with the oil industry with "State of Fear" (with rain forest venom dart shooting environmentalists driving Priuses) he wrote some really good science fiction (like "The Andromeda Strain"). In a previous book "The Terminal Man" he wrote about a man who had electrical impulses providing him with biofeedback (which he abuses). Substitute lasers and Voila!
    It was later made into a movie. Anybody see it?

      Exactly. The further science comes, the closer scientists will be to proving the existence of the Flying Spaghetti Monster: The source of creation, consciousness, and morality. Finally, we can have world peace when the people of Earth are united in worship of the one, true God.

      We've been over this. God is sufficient but not necessary for consciousness. It's far too early to tell either way right now. Keep working on the Hard Problem:-)

        God is sufficient but not necessary for consciousness.

        That's a completely meaningless statement, since both "God" and "consciousness" are vague concepts that nobody can define without some serious hand-waving.

        • You are confusing "nobody can" with "I cannot". Consciousness is not yet defined, but it will be. It's not a philosophical, but rather physical concept. All physical concepts, however complicated, are definable.
          • I knew I should have qualified it with an "at the moment" the second I hit submit, but your "it will be" isn't a given. We might find out how it works (and I hope we will), but perhaps we are fundamentally unable to.

            But we may construct an AI who can figure it out. (Who will subsequently be unable to explain it in a way out monkey brains can grasp it.)

              and that is the point where the AI decides we are no longer the creator as we cant understand something basic, Decides we are lying to them and unworthy and starts a systematic extinction of the human race.

              you Killed humanity sir.. I hope you can live with that.

            • Can any system transcend itself? Can humans never understand consciousness? Isn't this the core of Gödel's Incompleteness Theorems? Aren't too many rhetorical questions annoying?
        • There's nothing wrong that that statement though - proving one vague sufficiently proves the other, but to prove the other it is not necessary to prove the first.

    • until they realize finally that the brian does not produce consciousness but rather, is an interface for it. When they do realize that, maybe they'll be a little humbled by those who have been saying as much for the last several thousand years and won't be so quick to discount such things in the future.
