Researcher Implants Laser-Activated Brain Cells 98

Posted by samzenpus from the listen-to-the-light dept.
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.'"

    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.

        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.

        There's an Isaac Asimov story with this as the theme. The problem (in the story) is, you have to have it plugged into a 110v AC outlet. It's a detective story, an addict is murdered when someone makes his electric cord so short he can't reach the kitchen or bathroom, so he starves to death as he can't bear to unplug it.

        I can't remember the story's name, but iirc the book it was in was titled Supermen.

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.

    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.

    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.
