International scientists have managed to transmit words from one brain in India to another in France. The way this works is that an EEG is is placed on the head of one person. The person thinks of a specific word, then the input is fed to a computer, the computer takes the signal and turns it into binary data. That gets e-mailed to another computer in France over the internet, where the signal is fed to a transcranial magnetic stimulation device placed on the head of another subject. The device stimulates the visual regions of the brain which produces phosphenes, which are flashes of light that the person perceives. The person was trained to interpret the flashes and make out the words produced.
