Nowadays, the communication (even when it includes non-verbal contents) is still limited by the words and symbols accessible to the sender and understood by the receiver. Everyone knows, for example, how difficult is putting one’s own feelings into words. That’s because not all of the information which is available to our brain is available to our consciousness, so we can’t voluntarily put in linguistic form.
The idea of direct brain-to-brain communication will allows the information in the brain be transferred directly in the form of the neural code, bypassing language altogether.
This has been putting into practice by the Neuroscience Program at WSU (Washington State University), who had demonstrated how to control other person’s brain from afar, just communicating through a brain-to-brain communication channel which is able to interpret the orders of the emitter. To show us the certainty of the advancing,they decided to create an experiment: There were two participants. One playing the role of the “sender” and other playing the role of the “receiver.”
Both of them had to carry out a specific task on a computer game, which goal was to defend a city from enemy rockets. The sender must to demolish the rockets with a cannon, but there was a problem: he couldn’t watch the screen. The only one that could watch the course of the game was the receiver, so the had to play cooperatively, and the required cooperation could only be achieved through direct brain-to-brain communication. He had to be very concentrated about shooting, because his partner’s finger are going to shoot in his place. The first one wore on his head an electroencephalography (EGG) that records the electric signals of his brain. The second one had a transcranial magnetic stimulation machine on the brain area that controls the motor signals. The idea could be achieved using a Brain-to-BrainInterface (BBI) resting on two pillars: the capacity to read useful information from neural activity and the capacity to write digital information back into neural activity.
The three pairs of subjects correctly identified and destroyed 83.3%, 25.0%, and 37.5% of the rockets respectively during the experimental blocks, but, as Andrea Stocco (the study’s co-author) says, this numbers don’t reflect the efficiency of the technology; it should be evaluated depending of the subject’s precison.
I’ve looking for an article which attracts my attention, and this one has got it. I think that the direct brain-to-brain interface is an important contemporary technological development for advancing human communication, and this results show us that current technology is sufficient to develop devices for rudimentary brain-to-brain information transmission in humans. Thanks to this experiment, brain connection are closer than ever.
