Direct brain interface between humans

Sometimes, words just complicate things. What if our brains could communicate directly with each other, bypassing the need for language.

University of Washington researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team’s initial demonstration a year ago. In the newly published study, which involved six people, researchers were able to transmit the signals from one person’s brain over the Internet and use these signals to control the hand motions of another person within a split second of sending that signal.

At the time of the first experiment in August 2013, the UW team was the first to demonstrate two human brains communicating in this way. The researchers then tested their brain-to-brain interface in a more comprehensive study, published Nov. 5 in the journal PLOS ONE.

“The new study brings our brain-to-brain interfacing paradigm from an initial demonstration to something that is closer to a deliverable technology,” said co-author Andrea Stocco, a research assistant professor of psychology and a researcher at UW’s Institute for Learning & Brain Sciences. “Now we have replicated our methods and know that they can work reliably with walk-in participants.”

  • Well, I suggest to everybody to read carefully the “TMS Procedure” section of the article, located on Plos ONE (an article openly published! That’s commendable): it sort of clarify what the acomplishment actually is. So no Vulcan mind meld yet ;).

    What it seems to happen here is not really a direct mind to mind connection with an exchange of data, but a mind driven TMS pulse. Which is rather different from what the source post’s title seems to suggest…

    The very interesting bit is the trigger procedure to cause the sender’s EEG to fire the TMS on the other end. The closest analogy I can come up is clicking a mouse button by wearing an EEG cap instead of actually going out and clicking it with your finger -and transmitting that over the internet in real time is really no challenge; what is (at least, can be) a challenge is triggering the EEG in real time… Actually, I’d be very interested in the trigger’s algorhythm, since thinking up smart trigger bits is sort of what I do.

    An interesting development I can imagine (and part of me hopes to read about in the future) is actually targeting the cannon and firing it, instead of just firing it by making the receiver’s hand jolt.

  • Good catch. I agree. Also, in this article and previous articles I’ve seen on similar research they emphasize that the communication happened “over the Internet” as if somehow that was more meaningful than if the communication had been just over some local LAN.

    That would be one hell of a chess game !

    Please don’t let the advertising / propaganda industry get hold of this research. They might try to exercise even more mind control than they already have !

    Beings communicate often without direct communication and without wires….Its documented as mothers intuition or even maybe similar to twin intuition….there’s some kind of invisible bond between the two….a genetic frequency that vibrates at the same wavelength or something…I’ve felt this a few times….so I’m curious about what that is….
