Scientists Connect the Brains of Three People, Allowing Thought-Sharing (sciencealert.com) 136

An anonymous reader quotes ScienceAlert: Neuroscientists have successfully hooked up a three-way brain connection to allow three people share their thoughts -- and in this case, play a Tetris-style game. The team thinks this wild experiment could be scaled up to connect whole networks of people, and yes, it's as weird as it sounds. It works through a combination of electroencephalograms (EEGs), for recording the electrical impulses that indicate brain activity, and transcranial magnetic stimulation, where neurons are stimulated using magnetic fields.

The researchers behind the new system have dubbed it BrainNet, and say it could eventually be used to connect many different minds together, even across the web.... For now it's very slow and not fully reliable, and this work has yet to be peer-reviewed by the neuroscience community, but it's a glimpse at some fanciful ways we could be getting our thoughts across to each other in the future -- maybe even pooling mental resources to try and tackle major problems. "Our results raise the possibility of future brain-to-brain interfaces that enable cooperative problem solving by humans using a 'social network' of connected brains," writes the team.

    The last piece of the puzzle has fallen into place. We now have the technology against the impending Kaiju attacks.

    Wait, how does a nuclear reactor get used as a nuclear bomb again?

    • More like, finally the government can directly control our brains to save us from ourselves.

      • Some level of brain control has long been possible, both chemically and surgically. _Thought_ control can even be done by controlling speech and other behavior. _Reading_ thoughts is a far more subtle task. EEG's, for example, average the electrical impulses from quite a wide area of the brain, so the transmission is not subtle.

        If you could even drop a nuclear reactor from an airplane, all you would get is a radioactive mess. Certainly bad, but almost certainly no catastrophic mushroom cloud.

        Nuclear bombs are carefully designed to put fissile material into a critical-mass state very rapidly, to release a great amount of power over a short time-period. Nuclear reactors are designed to do it very slowly, to release a moderate amount of power over a time-scale of months or years.

      Because writers are dumb and audiences will hoot for anything that goes boom. Or... very, very bad nuclear engineers.

      Easy! A three way is a switching device with 3 connectors instead of 2. You typically use 2 of those devices to be able to turn on the light downstairs and turn it off once you get upstairs. 4 way switches exist as well although they are rarer.

    It's called talking. We've been doing it for a long time.

    It's a bit on the easy side, because it's aimed towards youth, but in those books people get connected via a small chip in the nose and it has interestingly bad effects the more people get connected.

    Just watch the participants at the staged "Trump" rallies. No plugins or wire necessary there. If the adage "great minds think alike" is a truism then it is also true that people with shit for brains are equally capable of thinking alike.

    in 100 years or so when it actually works, some guy is going to get sued for sexual harassment because he forgot to turn it off when he started thinking about a coworker in an inappropriate way.

      But then the coworker feels what this guy feels and the recursion gets its initial stage. The end condition is situation requiring a change for all involved, at the same time. The process cannot be stopped once started.

  • They weren't sharing thoughts. They were sharing a signal. Specifically, an LED which, they were told before the experiment, represents a move in Tetris. They aren't communicating anything of great depth, the government can't use this to read your thoughts and find out that you ran a red light on the way home last night. The whole thing could literally have been replaced with two wires. Typical web jabber that sometimes pretends to be "journalism".

    • Indeed, merely looking I to someone's eyes will give you a stronger connection to their brain than this system.
    • by WoOS ( 28173 )

      Plus, according to the article, the receiver would see the signal as "phantom phosphene [wikipedia.org] flashes", meaning flashes of light which were induced into his brain by magnetic fields.
      If one really wanted to transmit "thoughts" that way, the receiver would at least have to be rather quick in morse code. Actually the receiver just learned to distinguish different frequency of flashes and to rotate a tetris block depening on it.

    The brain consists of incredibly sophisticated networks on neurons (and glia), that perform the information processing that probably leads to thoughts. The resolution of transcranial stimulation, and the knowledge of the targeted brain regions, are both too low to call this sharing thoughts. Tell me you can do multi-point m scale read/write transcranially, know the anatomy of the targets brain region in m scale in a non-destructive way, and we can talk about "thought sharing" (or even thought insertion).

    This *headline* oversells the results, and underestimates the complexity. It's nothing but bait.

    • by religionofpeas ( 4511805 ) on Sunday October 07, 2018 @04:29AM (#57440476)

      Also, brains are only superficially alike in structure. Fine details differ from person to person, so you can't just copy a thought from one brain to another. The only way to do this is to set up a communication channel, and then the two brains practice to convert their thoughts into a mutually agreed upon signalling system and back.

      A few comments back I was saying that we already have this, and it's called "talking". It got moderated funny, but I was actually serious.

      • by Knutsi ( 959723 )

        It's not funny, it's a very good point (: Language is a system to share throughs using rapid sequential air compression. We dont experience it like that of course, because our conciseness sits at some point(s) in an enormously complex processing system that masks the underlying machinery.

  • Those Borg babies...they're so cute when they're young.

  • So how long before precrime units start wiring up precogs this way?

    • I dunno, but the local cops already started claiming that their job is to "prevent crime." So maybe too late.

    It's called a MAGA hat.

    There are enough voices in my head, thank you very much.

  • So this it the first step in assimilating.
  • Great. Next steps will be: refining this so that thoughts can be interpreted and documented, then being able to do it wirelessly, then wirelessly over distances of, say, a few hundred meters. Then nosy corporations and governments can spy on what you're thinking in your own home, closing off the 'last mile' of individual privacy. We'll have to get Faraday cages installed where we live to even keep our thoughts private. Then Amazon will come out with a 'digital assistant' that gets thoughts via just thinking
