Scientists Link Brains With Revolutionary Device
A group of scientists has successfully connected the brains of 3 individuals…
…and enabled them to share their ideas with each other via an interface they have dubbed BrainNet.
The researchers, from the University of Washington and Carnegie Mellon University, recently released their findings …
…and explained this intriguing process has to do with the combination of two existing technologies:
1. Electroencephalography (EEG) and
2. Transcranial magnetic stimulation (TMS).
To put it simply, 1 brain’s activity signals are recorded and then moved non-invasively to another brain using stimulated neurons.
During their evaluations, the researchers hooked up three human subjects to the interface with electrodes in their scalps and tasked with collaborating to solve a game similar to Tetris…
…with the goal of falling cubes into vacant spaces.
The three people were permitted to communicate but only by utilizing just their brains as to how the cubes should be rotated and dropped.
So how did it all work?
Among the three people was given a particular function and became known as the Reciever.
The Reciever also couldn’t find the game screen, and thus they needed to require the Senders, who were in full view of the screen,
to issue them commands via the mind system as to how the cubes should be moved.
Depending on what they looked in, the Senders used binary to inform the Reciever if they should rotate the cube or leave it alone.
Not only could the Reciever interpret these commands and move the cubes accordingly, but they might also tell if one of the Senders were trying to trick them.
Researchers artificially injected sound into one of the windmill’s sign and the Reciever managed to identify which of both Senders was more reliable and interpret their information rather than the faulty transmission coming out of the other.
In total, researchers discovered that five groups of three subjects each managed to successfully use BrainNet to complete the Tetris game.
It’s worth noting that this intriguing interface did require significant external intervention to attain effects.
While this in no way implies telepathy will become a fact, the findings are quite promising for what the future may hold in similar media capacities.
Right now, the system only transmits a brief flash of information at one time, and the process is fairly slow and unreliable,
but the team of scientists believes their findings suggest the interface could see significant expansion. As explained in the analysis,” these results raise the possibility of future brain-to-brain interfaces that enable joint problem solving by humans societal social network’ of connected brains.”
So who knows – maybe one day we will be able to apply this so-called”social network” to collaborate with different people’s brains from all around the world.
