According to a new study released by PLoS, a group of scientists have successfully sent a message between two brains, without actually implanting anything in either person. Yes, this was all achieved across a normal skull without any wires being inserted.
Simply put, one person was shown an image, which was picked up by an external set of sensors which measure brain activity (known as an electroencephalogram or EEG), and then this activity was sent over the internet to a robot-assisted, image-guided transcranial magnetic stimulator, which stimulated the message into a second person’s brain. The result was the second person also saw a version of the image.
Now, before you start thinking that we’ll soon be able to reading each other’s minds, or ever worse, implanting false memories into people, you have nothing to worry about (yet…).
The message being sent was the words “Ciao” and “Hola” which had been turned into binary, which was wither an “on” or “off” image. When the first person saw those images, they were told to think of one or two actions (moving their feet or hands), which the EEG could then read. The person receiving the message would then experience a slight image being projected into their peripheral vision to denote on or off. Once the binary message was complete, it could be turned back into the original word.
