 Scientists pioneer verbal brain-to-brain communication for the first time 
in history

Digitized telepathy
In the future, the act of texting will become synonymous with calligraphy, 
quaint, but ultimately useless. Telepathy is slated to be the next big 
medium of communication, and fortunately for us, it's right on the horizon. 
An international team of researchers have, in a first-of-its-kind study, 
successfully transmitted a message 5,000 miles from one person's brain in 
France to another person's brain in India without any invasive surgery.

We wanted to find out if one could communicate directly between two people 
by reading out the brain activity from one person and injecting brain 
activity into the second person, and do so across great physical distances 
by leveraging existing communication pathways," said co-author Alvaro 
Pascual-Leone, MD, Ph.D, director of the Berenson-Allen Center at Beth 
Israel Deaconess Medical Center and Professor of Neurology at Harvard 
Medical School.

The team of researchers, who also included bright minds from Starlab 
Barcelona in Spain, Axilum Robotics in Strasbourg, France, used an 
Internet-connected electroencephalogram (EEG), and a robot-assisted, 
image-guided transcranial magnetic stimulation to excite the brain from 
outside of the scalp, and perform the communication.

Essentially, the procedure functions similarly to a brain-computer interface 
control in which electrodes placed atop a human subject's scalp harness the 
electrical currents of specific thoughts before a computer translates them 
into a robotic action. In this case, the output was another human being 
rather than a computer.

A total of four participants between the ages of 28 and 50 were used in the 
experiment; one participant engaged the brain-computer interface (BCI) to 
generate the thought while the other three sat in the computer-brain 
interface (CBI) to receive it. When the BCI participant thought the words 
"ciao" and "hola," the computer translated the words into binary code and 
sent the data to the three participants on the CBI side. After being shown 
the code, the users were asked to move their hands for 1 and their feet for 
0. Next, an EEG recorded the electrical signals in the sender's brain as the 
recipients thought these actions to translate the binary into a neural code.

Here comes the juicy part: this newly formed neural code was transmitted to 
the recipients using a gentle stimulation of their visual cortex, creating 
bright lights in their peripheral vision representative of the original 
binary string; light on one side meant "1" whereas light on the other meant 
"0." The data was then be decoded and communicated as "ciao" and "hola."

Despite the simplicity of the context, the experiment was the first 
successful attempt at digitizing telepathy. The researchers remain confident 
that technology will provide a seamlessly manner of communication in the 
near future, supporting both brain-to-brain and brain-to-machine 
interfacing. The entire research paper can be downloaded here.
