Intel Says Brain Implants Could Control Computers By 2020 314

Lucas123 writes "Scientists at Intel are working on developing sensors that would be implanted in a person's head in order to harness brain waves that could then be used to control computers, televisions, cell phones and other electronic equipment. Intel has already used Functional Magnetic Resonance Imaging (FMRI) machines to determine that blood flow changes in specific areas of the brain based on what word or image someone is thinking of. People tend to show the same brain patterns for similar thoughts. 'Eventually people may be willing to be more committed ... to brain implants. Imagine being able to surf the Web with the power of your thoughts.' said Intel research scientist Dean Pomerleau."

        Your fear prevents you from evolving.

        Direct neural communication between groups of humans (and augmented by computers) would produce a thinking, conscious being who's cognitive capacities are a step above that of a human (in the same sense that human cognition is a step above that of monkeys).

        This pattern is not new. Single-celled organisms formed cell colonies, which were an evolutionary step up, only after they opened their membranes to each other to allow direct chemical communication. Cell colonies accepted similar levels of integration in the formation of tissues, organs, and gargantuanly huge interconnected ecologies (specifically, humans).

        Allowing direct neural reads and writes is the natural continuation of this pattern. Your fear will prevent you from taking this evolutionary step up. You will eventually sit in a zoo throwing dung at tourists, while the true visionaries reach beyond the stars.

    I recently heard an NPR article about this kind of thing.

    Using real time MRI, someone could be presented with flashcards of common objects (screwdriver, igloo, flower, etc). When they thought about those objects, certain areas of the brain lit up.

    The scientists said that when you think of a screwdriver, there isn't a single "screwdriver" area that lights up. Instead, you think of how it looks, what it feels like in your hand, what it's used for. You might think of construction workers, or your favorite screwdriver in your workbench at home. So lots of areas in the brain "light up".

    What's amazing to me is that it appeared to be the SAME AREAS for DIFFERENT people.

    As an example of this, the NPR production assistant (who was just visiting and helping with the interview) got hooked up to the MRI and was shown the flashcards. The computer, by looking at her brain, successfully guessed 10 out of 10. Even though the computer "learned" from someone else!

    I suppose someone who'd never seen a screwdriver before wouldn't have the same sort of response, so it's probably limited to people with the same cultural backgrounds.

Do you have any idea how many of these things you'll need shoved through your skull to be able to fore go just those two activities?

And just who makes enough money to pay for undergoing dozens (at least!) of invasive implantation surgeries requiring real time CT or MR imaging? You insurance damn sure won't pay for it. And don't give me that "for the disabled" crap -- they don't get the expensive stuff either.

    You don't need implants for brain "waves". Implants are better suited for detecting neural firing patterns on a much smaller scale. But you can get the job done with "waves" (EEG) without having to trephan yourself.

    There are now EEG systems that have the premap on the electrode, making impedance issues irrelevant and signal balancing automatic. There are EEG analysis packages that use continuous wavelet analysis to do time/frequency analysis similar to the "thousands of channels" analysis radio-astronomers enjoy. Between these two, and 'training' a system to recognize a particular person's EEG patterns well enough to control a device like a computer, the other EEG related problems like skin potentials, EMG and EKG artifact become non-issues. And as far as localization, I can reliably localize 40 to 50 signals simultaneously with this technology using a high density (256 or more) electrode EEG.

    This technology exists now. The computing power necessary to operate in as a control system in real time is beyond most people's ability to purchase. So if the nice folks from Intel will kindly put down the cranial drill and get back to what they're good at, maybe by 2020 we can have the sort of computing power sitting on everyone's desk if not sitting in a handheld device in their pocket.

    And get away from that fMRI. I don't care what you think you saw. I saw the fMRI "brain scan" of the dead salmon showing it lighting up as it recognized a human emotion from a photo it had been shown before (but while still dead).
