Hardware Implants Mimic Brain Cells

Posted by ScuttleMonkey on Wed Apr 04, 2007 12:07 PM
from the memory-upgrade dept.
An anonymous reader writes "PopSci is reporting that Ted Berger, a USC scientist, has been working to engineer a brain implant the mimics the functions of neurons. Early tests on rat brain cells have shown promise, and if successful, Berger's implant could remedy everything from Alzheimer's to absent-mindedness — and reduce memory loss to nothing more than a computer glitch"

      Does the main bus of your computer run Java? Does it run x86 instructions? Does it run anything of the sort?

      This technology appears to be mainly about routing signals, not generating or processing them. It assists with memory by properly storing and retrieving those signals, but it does not interpret them. (As evidenced by his comment, "I don't need to understand music to repair a CD Player.")

      The article is correct, however, in that this technology will bring us one step closer to understanding how the brain functions. Since these neurons are artificial, the signals passing through can be sampled and stored on an external device. This would allow researchers to reverse engineer many signals in parallel rather than trying to trace one or two signals through the brain as they've been doing.

      Unfortunately, I doubt this technology will outright unlock the secrets of conciousness. Remember how neural networks were intended to be an invaluable research tool into self-awareness? Well, the resulting networks ended up working in a similar but fundamentally different way from the organic brain. That fundamental difference prevented the networks from fully simulating the human brain.

      So we'll take the next step forward, and learn where our previous mistakes were. Not to mention, uncover thousands of new questions. :)

    • IIRC the Java spec requires a 32-bit von Neumann architecture supported by a filesystem that can support long filenames. If you're smart enough, in principle you can (inefficiently) simulate all these features yourself with a pencil, lots of scrap paper, the information in library JAR files, and the JVM spec. So if the artificial neurons can implement the functionality of the natural ones in intelligent people, you get Java support "for free" and you can avoid "reinventing the wheel" (investors love to hear

    I am torn over this idea because clearly it represents a potential major advance in science and a cure to several insidious, incurable (as of today) diseases. We could probably extend the life expectancy of humans by a decade or so.

    However, it also presents some less optimistic possibilities: for example, someone might be able to "program" humans as we program computers today. Imagine some terror organization such as Al Qaeda creating a fearless, seven-foot, feel-no-pain specimen....

      A decade? That's much to short sighted. Something like this could eventually enable immortality. Think about it - if you replace enough neurons, pretty soon most of who you are would live inside the machine. At that point, who's to say where your consciousness lives? Whats to stop you from transferring to a completely electronic brain and living on as long as you have juice? Of course, there's a lot of metaphysics around this - would "you" still be "you", what if you made a copy, etc. etc. Fascinating stuff. Of course, we're a long ways off from it, but if you look where transistors and such were 50 years ago, its not such a stretch to think this will be a possibility in the next few centuries.

    I find the philosophical issues especially interesting. How much of the brain can be replaced before the original "self" no longer exists? I guess it doesn't really matter in the scheme of things so long as the pattern is replicated . . . I guess our brains are constantly gradually replaced throughout our lives--the molecules we were born with aren't necessarily the molecules we're currently made out of.

    At what point are we no longer human? Our thoughts stem from the firing of neurons. If half of those neurons are computer chips, was it a human thought or a computer generated though. I'm all for finding cures to Alzheimer's disease, but I do not want to be a glorified computer case. I did not read the article (yet), and I realize that the part of the brain discussed in the article is probably different than the creative parts of the brain, but I still think its a valid question; at what point do we stop being human (as we know it)?

    I don't thing this could be useful for any Alzheimers treatement in a very long time if ever (and we've probably solved it in another way even if it ever gets there).

    As I understand it Alzheimers is basically a case of protein misfolding creating amyloid plaques on the neurons and that really screws up the functions (perhaps some with actual medical/biological knowledge can expand on that). Anyway, it's not just one part that you can hot-swap to use a computer term... it's happening all over the affected area. So you're not going to just plop in a new frontal lobe and call that a cure are you?

    And yet the researcher goes on and makes a big point of this:

    Today an estimated 4.5 million Americans suffer from Alzheimer's, at an annual cost of some $100 billion, according to the Alzheimer's Association and the National Institute on Aging. "And those figures are just going to climb as my generation gets older," says Berger, who can rattle off the grim statistics from Alzheimer's and other brain disorders that disturb memory. Another 5.3 million Americans are victims of traumatic brain injuries
    I do belive that this technology could have many many wonderful uses but that Alzheimers isn't one of them... and by using on of the scariest biggest diseases just to flag down some interest he's doing not only himself but the whole research area a disfavour.
  • Suppose you add artificial neurons to a brain, and remove natural neurons as they die. Eventually, you end up with your mind running entirely on artificial neurons. Is your mind now effectively immortal?

    And is it still you? Or a copy of you running on the artificial brain? If it is a copy, when does it cease to be you?

  • then, we've got an interesting interface here. Sprinkle a few of these into the motor cortex, then have the person work with feedback systems to learn to differentiate those controls from the natural ones. From there, all sorts of potential exists for communication.

    Instead of the computer being an active part of the brain, it becomes more like a PDA that you don't have to carry. Motor feedback signals, generated from the neurons would then become something like morse code.

    This guy is making chips that can "talk" to the brain in signals the brain can understand, even if he doesn't know what the signals mean. Pure mimicry.

    Oddly enough, the people mentioned in Hacking Our Five Senses (Apr-03-2007) [slashdot.org] are using similarly arbitrary but mechanical means to also send signals to the brain (admitedly using existing pathways).

    Would it be possible to combine these two techniques, as well as a few miniturization techniques (and perhaps standard "ports") to enable people to not just replace storage capacity but indeed "add" senses?

    Instead of using a belt to buzz "north", use implants to send one of a set of predetermined signals. It won't matter what the signals would originally mean (if anything) - because if Hacking Our Five Senses is any indication, the brain is capable of creating maps for the the new signals anyway.
