Monkeys Made Smarter With Prosthetic Device 102

An anonymous reader writes "Scientists have successfully restored and, in some cases, enhanced decision-making ability in brain-damaged monkeys on cocaine by connecting a prosthetic device to their brains. 'In the study, the scientists trained five monkeys to match multiple images on a computer screen until they were correct 70 to 75 percent of the time. First, an image appeared on the screen, which the animals were trained to select using a hand-controlled cursor. The screen then went blank for up to two minutes, followed by the reappearance of two to eight images, including the initial one, on the same screen. When the monkeys correctly chose the image they were shown first, the electronic prosthetic device recorded the pattern of neural pulses associated with their decision by employing a multi-input multi-output nonlinear (MIMO) mathematical model, developed by researchers at the University of Southern California. In the next phase of the study, a drug known to disrupt cognitive activity, cocaine, was administered to the animals to simulate brain injury. When the animals repeated the image-selection task, their decision-making ability decreased 13 percent from normal. However, during these "drug sessions," the MIMO prosthesis detected when the animals were likely to choose the wrong image and played back the previously recorded "correct" neural patterns for the task. According to the study findings, the MIMO device was exceedingly effective in restoring the cocaine-impaired decision-making ability to an improved level of 10 percent above normal, even when the drug was still present and active.'"

    • No, but I'd imagine this might have applications in people who have suffered brain injuries. It sounds like they can essentially use some kind of resonance effect, so if this can be replicated for people who can physically walk but can "no longer remember how" then it's potentially useful. However, if they're simply playing back a pre-recorded action then there is limited application, it's not going to revive lost speech centers for example, and extensive physiotherapy which helps to develop new pathways

        it's not going to revive lost speech centers for example

        The device is able to read neural activity, and playback neural activity. Lets say the speech center is lost, when this technology is a little more mature you could pump speech center communications to the different parts of the brain while offloading the actual processing to a device.

        Looks like it we might just see cyberneticly augmented intelligence in our lifetimes after all.

        • We've arguably got it already. Mobile phones "augmenting" pub quiz teams are a big problem.

          I did wonder about speech, but if you're simply playing back the neural activity that generates "hello" then you have to tell the device to do it, and giving the command "say(hello)" might as well lead to a speech synthesizer. Walking, however, is a repetitive activity that could be controlled by this for minutes or hours with one command.

  • The feed back device didn't improve the monkey's intelligence, it simply undid some of the damage the crack did to them.
    At best its a retraining aid, and its not clear if it had any long term effect after discontinuing the feedback.

    Since each feedback profile was learned from the monkey itself, there's no indication that you could apply that pattern to
    other monkeys, or the undamaged monkeys to make them learn quicker.

      Emphasis mine. Your other points may be valid, but this technique certainly did more than just undo the effects of the drug.

      • Except that "normal" here means what the control group did, after receiving the cocaine.

        It looks more like a mind backup (or control) tech than a mand amplifying one.
