Researchers link three human brains to play 'Tetris' as a team

Researchers from the University of Washington, where the first non-invasive human-to-human brain interface was performed in 2013, have revealed BrainNet, which is described as a ‘brain-to-brain’ social network.

The work described in a paper explains how BrainNet uses technology to send signals to and from different brains—don’t expect any Charles Xavier-style powers just yet. The system used three people: two who send the brain signals and one who receives them. All of those taking part are attached to an electroencephalogram (EEG) device that records electrical activity in the brain, while the person receiving the signals is also connected to a machine that causes transcranial magnetic stimulation (TMS), which stimulates reactions in the brain.

The three subjects were linked to play what is essentially a very simple Tetris-style game. The senders, who could see the whole screen, would focus their eyes on a 15Hz flashing LED if they wanted to rotate one of the pieces. This would generate brain waves at the same frequency, which would be transmitted to the receiver. This person, who could only see the falling pieces, receives the signals, which are then converted by the TMS into a spot of light in their vision—an indication that the block needed to be turned.

Using 15 people spread across five groups of three, the overall accuracy was 81.25 percent, which is even more impressive when you consider that the researchers occasionally made one of the senders send incorrect signals, leaving the receiver to figure out which instruction was correct.

“Using only the information delivered by BrainNet, receivers are able to learn to differentiate the reliability of information conveyed to their brains by other subjects and choose the more credible sender,” the researchers said. “This makes the information exchange mediated by BrainNet similar to real-life social communication, bringing us a step closer to a ‘social network of brains.’”

Last year, Elon Musk confirmed that he would become the CEO of a startup called Neuralink Corp. aimed at merging computers with the human brain, which could eventually lead to “consensual telepathy.”

So that's like nVidia's SLI bridge. Finally, no more wasting time explaining things to each other.

I suppose, you can get one for your wife too, see how good she is at ........ Tetris.

I'm guessing for this thing to work well, there must be a short spread in the IQ level of the connected individuals. So, for instance, if you connect Trump with a chimp, you should expect a perfect harmony of thought and creativity.

You just had to make this political didn't you lol. Sad, but I hope you feel better now.

Why do people always think it is political, whenever a monkey is mentioned?
First of all, a chimpanzee isn't a monkey, it's an ape. Second, there are two species of chimp, Pan Troglodytes (the common chimp), and, Pan paniscus, (the bonobo).

P troglodytes likes to fight, while P paniscus likes to f***. Given the history of human "civilizations", all of which were formed by killing, pillaging, and finally raping the inhabitants of conquered territories, you can easily see that man (Homo sapiens), has evolved and transcended other great apes, by inheriting "the best qualities", of the two other Pan species.

Therefore, you couldn't really make this "political", unless you connected a brain from each of the two chimp species to Trump's brain.

There was a pygmy species of human discovered recently, "Homo floresensis". Scientists differ as to why they went extinct. The real reason, however politically incorrect it might be to mention it, is that Homo sapiens more than likely ate them..:eek: But I digress....:laughing:
