It may seem like science fiction, but researchers have conducted an experiment recently where they successfully transmitted thoughts using no hands, no words, no voice, no typing and no gestures … just brain-to brain communication.
A volunteer in Kerala, a southern state in India thought the words `hola’ – `ciao’ and another man in Strasbourg, France, successfully received the two greetings in his brain.
Researchers from the University of Barcelona and Harvard Medical School and Axilum Robotics in France, making brain stimulation equipment and robotics, carried out these experiments in April this year.
The person in Kerala was connected to a wearable EEG system plugged into a laptop. EEG (electro-encephalograph) measures tiny electric currents in the brain. Electrical currents in the brain are linked with different thoughts that are then fed into a computer interface.
A computer analyzed the signals and then using electrical stimulation implanted it in the receiver’s mind, the message appeared as flashes of light in their vision.
