Could we soon send emails 'telepathically'? Scientist transmits message into the mind of a colleague 5,000 miles away using brain waves
The researchers used electroencephalography (EEG) headsets which recorded electrical activity from neurons firing in the brain to convert the words ‘hola’ and ‘ciao’ into binary. In EEG, electrical currents in the brain are linked with different thoughts that are then fed into a computer interface
Brain-wave sensing machines have been used to ‘telepathically’ control everything from real-life helicopters to characters in a computer game.
Now the technology has gone a step further by allowing someone in India to send an email to his colleague in France using nothing but the power of his mind.
The researchers used electroencephalography (EEG) headsets to record electrical activity from neurons firing in the brain, and convert the words ‘hola’ and ‘ciao’ into binary
In EEG, electrical currents in the brain are linked with different thoughts that are then fed into a computer interface. This computer analyses the signal and controls an action.
In the latest study, published in Plos One, researchers decided to replace the computer interface with another brain to receive the signals.
In the initial test, the greeting was sent from a volunteer in Thiruvananthapuram, India to Strasbourg, France. There, a computer translated the message and then used electrical stimulation to implant it in the receiver’s mind. This message appeared as flashes of light in the corner of their vision.
The light appeared in sequences that allowed the receiver to decode the information in the message.
Researchers then conducted a similar experiment in which thoughts were successfully transmitted from two participants, one in Spain and one in France.
The second experiment resulted in a total error rate of just 15 per cent, with a 5 per cent on the encoding side and roughly 11 per cent on the decoding.
The technology was developed as part of a collaboration between the University of Barcelona in Spain, Axilum Robotics in France, Harvard Medical School and Starlab Barcelona in Spain. According to the researchers, this is the first time humans have sent a message ‘almost directly’ into each other’s brains.
‘We anticipate that computers in the not-so-distant future will interact directly with the human brain in a fluent manner, supporting both computer- and brain-to-brain communication routinely,’ they wrote.
Human-to-brain technology is also gaining traction. In May, German scientists showed how seven pilots used mind control to fly with ‘astonishing accuracy.’ In a simulation, several of the pilots managed the landing approach under poor visibility, while one was able to land a few metres from the runway’s central line.
Meanwhile, in June, University of Oregon researchers unveiled a device that claimed to be able to monitor memories in near real time to see what a person is thinking.
