The ability to 'telepathy' is not too far away

Brain wave sensors have been used to control many devices through 'telepathy', from helicopters to video game characters.

The researchers used EEG electroencephalogram to record electrical activity released by neurons in the brain, and to convert the words 'hola' and 'ciao' into binary code.

According to the latest research published in PLoS ONE, scientists decided to replace the computer interface with another brain to receive signals.

Now technology has gone a step further by allowing someone in India to send e-mails to their colleagues in France with just the power of the brain.

In the initial test, a volunteer in Thiruvananthapuram, India, greeted the recipient in Strasbourg, France. There, this message is translated by a computer and implanted into the recipient's mind through electrical stimulation.

The message appears as a flashing light in the corner of their vision. This light appears in certain order, allowing the recipient to decode the information in the message.

Researchers then performed a similar experiment, in which the thought was successfully conveyed from a Spanish person to another in France.

The overall error rate of the second experiment is only about 15%, with 5% on the coding side and about 11% on the decoding side. This technology was developed thanks to the collaboration between the University of Barcelona in Spain, the Axilum Robotics in France, Harvard Medical University and the STARLAB Barcelona laboratory in Spain.

In France, this message is translated by a computer and implanted into the recipient's mind through electrical stimulation.

According to the researchers, this is the first time humans have almost directly sent a message to the brains of others.'We predict that computers in the near future will interact directly with people in a proficient manner, being able to support both modes of communication regularly: from computers to the brain and from the brain to the brain. " scientists said.

Technology connecting human brain to computer is also attracting attention. In May, German scientists showed that seven pilots could control the aircraft with the mind with 'incredible accuracy'.

In a simulated test, some pilots achieved a landing method with poor visibility, of which one could land only a few meters away from the center line on the runway.

Meanwhile, in June, the University of Oregon announced a device that was supposed to be able to track human memories in real time to know what they were thinking about.
