UW Researchers Demonstrate First Direct Communication Between Human Brains 154

An anonymous reader writes "Opening a fascinating set of ethical and legal issues, researchers at UW Seattle have demonstrated the first device to allow direct communication between two humans' brains. Effectively, they allowed a subject to play a video game with another subject's fingers. For now, the communication is uni-directional, though they intend to extend it to bi-directional. EEG sensors are attached to a subject's motor cortex to detect 'motor imagery' — imagined hand movement, in this case. That activity is translated and sent over a computer network where it triggers a Transcranial Magnetic Stimulator (TMS) located over Subject 2's motor cortex. Effectively, Subject 1 imagines moving their hand, and Subject 2's hand moved."

    Subject 1 imagines moving their hand, and Subject 2's hand moved.

    I think I saw this premise in an adult movie once

      Then when it's controlled by someone else, it's even more convincing.

    Have you considered the very real posibility that brain may not have proper mandatory authorization and intput verification and anyone with local access can say stop your heart?

    • Definitely. Brute force attempts can often result in the person's brain being bricked. And that will definitely stop their heart.
    • If you want to stop someone's heart there are much cheaper ways. However, this may be the first one that works over the internet.

    • What if you "recorded" someone having a heart attack and then dying, them played that back over the interface? I don't think this device works on that level though, or else the receiver's heart and other automatic functions might have an issue...they might even sync up, or just freak out and beat twice as fast with a weird rhythm. It probably depends on where and what they are recording, and how close they are to the particular nerve bundle carrying those signals.

      Now I have. I'm pretty sure that anyone with local access can't stop the heart. I've never heard of anyone being consciously able to stop their own heart or even temporarily stall it like one can hold ones breath.
      If I were to guess I would say that the heart signal works on a hard-coded enough level to make it mentally impossible to stop.

      Now, holding the breath for someone else could be a fun experiment.

    Okay, let's just speculate about all the ways this could be misused:

    *-- Vending machines that make you reach into your pocket and pull out money whenever you pass by them.

    *-- Rich handicapped people buying time on poor people's bodies.

    *-- Rich people buying time on poor people's bodies, in order to do criminal things.

    *-- Police officers with a 'lay down with your hands behind your back' raygun.

    I'm sure I missed a few, any suggestions?

      They made a movie about that, except that it was "Rich people buying time on peoples bodies to do whatever the hell they wanted," and "Rich people buying time on death row inmate's bodies to make them kill each other."

      Vending machine would need a huge magnetic field, to hit passersby a few feet away from it in that particular spot. Assuming it was able to target the magnetic field well enough not to simply illuminate everything in the targets brain at once (doubtful), then it will still destroy all of the targets credit cards, cell phones and anything else that might be invented to let you pay vending machines in the ne

    Would this help people with locked-in syndrome? Would they be able to use someone else's hand to act? to communicate?
    Which one of the two people would have to have Parkinson's to make the resulting hand movements irregular?
    Etc., Etc.

    • I think this requires you to pick up signals from the originator's motor cortex. I don't know anything about the syndrome, so unless there is something to pick up you're not going to get anywhere.

      That said there could be signals, and they just don't go anywhere or are not strong enough... in which case I bet you could get it to work.

      The reverse might help too! By making the cortex do things, it does them, and consider brain plasticity...

    • Excellent idea, from my understanding of the process demonstrated above, yes, this could work, as this would be above the neurological level of the lesion in most patients suffering from locked in syndrome. - I am a physician.
  • What about emotions or perhaps even thoughts?
    Will it be possible?

  • Couples in long distance relationships eagerly await the results.

    • Without translating sight or touch, that could be really painful. If they can transfer touch sensations, well then - this is even more useful.

  • ... well, they sure do now.

  • FTFA: "Stocco said years from now the technology could be used, for example, by someone on the ground to help a flight attendant or passenger land an airplane if the pilot becomes incapacitated."

    Or, you know, use fly-by-wire. A normal computer-to-computer interface is sufficient here, and already exists and is in widespread use.

    • An example that is flawed for sure, what about a situation where someone needs emergency surgery and this could be performed by proxy by a willing bystander? There are definitely potential uses for a mature version of this technology, most of them are quite scary though. I do not like the idea of this being done to me. In reality though I think for all the 'save the day' scenarios in which this could be useful it would have to be a ubiquitous technology, now that's pretty damn unlikely even if it does matu
      • We might have a medical bag in the future that has a helmet with the magnetic transceiver in it. An immediate application would be field surgery, with a physician in a safe place performing life-saving operations in the troop transport via the vehicles encrypted sat signal. pop it on, do the work, and your good. Perhaps combine it with an immersive 3D computer technologies and remote cameras (and maybe even a bit of a finger/hand level feedback loop) this could go a long way. I can see a whole industry

  • For real, so much of this brain research stuff it scary as heck to me. Even the so called ethical uses seem pretty creepy.

    There was another research piece where they could associate negative or positive emotions with memories artificially. Some genius though it might be a way to fight PTSD, except I think he kind of overlooked the possible side effect associating positive emotions with death and carnage.
