Scientists have demonstrated brain-to-brain messaging, similar to telepathy, across a distance using a computer interface.

They transmitted the words 'hola' and 'ciao' in binary code from the brain of a person in India to the brains of three people in France, reports ANI.

The team of researchers from Starlab Barcelona, Spain and Axilum Robotics, Strasbourg, France, used internet-linked electroencephalogram (EEG) and robotised transcranial magnetic stimulation (TMS) technologies to transmit the message.

Electrodes attached to a person's scalp recorded electrical currents in the brain as a person was asked to consciously think about an action like moving an arm or leg. The computer interpreted the signal and translated it to a robotic control output. A second human brain was included on the other end of the system.

Four healthy adults participated in the study. One of them was assigned to the brain-computer interface (BCI) branch and was the sender of the words; the other three were assigned to the computer-brain interface (CBI) branch of the experiments and received the messages.

Using EEG, the research team first transmitted the electrical signal accompanying the greetings 'hola' and 'ciao' into the computer, then translated this into binary code and then emailed the results from India to France.

The recipients, blindfolded, received electric pulses from the robotised TMS system in the visual cortex of their brains. This triggered the experience of phosphenes, or seeing flashes of light that are not actually there. The record of these flashes when reported were translated into binary code and translated into the message.

The study was published in PLOS ONE.
