Modern technologies of “reading” of brain waves are used almost everywhere, starting from controlling the “power of thought” of helicopters and ending with computer games. However now technology has gone even further: a researcher from India sent a letter to his colleague to France using your own mind and only a small amount common technique, that is, almost telepathically.
Scientists used a headset to take electroencephalograms (EEG). She needed to record electrical activity neurons in the brain and converting the words Hola (“Hello”) and Ciao (“Bye”) into binary code.
Using EEG technology, researchers have learned to correlate electric currents in the brain with various thoughts. This information transmitted to the computer interface. The machine analyzes the signal and controls the action. However, this study decided replace the computer interface for receiving signals with another brain (previously, neurologists did this only with animals).
Researchers used an EEG headset to transmit data. (Figure PLoS ONE).

During the experiment, a greeting was sent by a volunteer from Thiruvananthapuram (India) to Strasbourg (France). There is a computer “translated” the message, and then used electrical stimulation, to convey the thoughts to the owner of the receiver implanted in the brain. The message appeared as a flash of light in the corner of the vision. the recipient.
The light appeared in a sequence that allowed the receiver to decode the message information. Then the researchers conducted a similar experiment in which thoughts were successful transferred from Spain to France.
During the second experiment, the total error rate was only 15%: 5% was allowed at the coding stage and about 10% at decoding stage.
In France, a computer translated a message, and then using electrical stimulation showed to the recipient.

This technology was developed as part of a collaboration between University of Barcelona, Axilum Robotics in France, Harvard Medical School and Starlab Barcelona. By According to researchers, this is the first time that people have succeeded forward a message almost directly from one brain to another.
We expect that in the not too distant future, the human brain will interact with computers directly, the authors report project.
This technology is rapidly gaining momentum. For example, In May 2014, German scientists showed how pilots could control the control of the aircraft with amazing accuracy, and in June 2014, Oregon researchers demonstrated a device which can read a person’s mind in real time.
A scientific article about this study was published in the publication. PLOS ONE.
