Brain-to-brain communication achieved!

Brain-to-brain communication achieved for the first time



Imagine a world that involves communicating solely through the brain. Instead of picking up your smartphone to make a call to a friend who lives miles away, what if you could don a cap and make your call telepathically?


It might sound like something out of science fiction, but an international group of scientists have done exactly that, by transmitting messages from one brain to another. Most impressively, the brains were 5,000 miles apart.


"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," says Alvaro Pascual-Leone, MD, PhD, Director of the Berenson-Allen Center for Noninvasive Brain Stimulation at Beth Israel Deaconess Medical Center (BIDMC) and Professor of Neurology at Harvard Medical School.


That existing communication pathway is the Internet, that very thing that allows us to communicate via our computers, tablets and phones. As it turns out, the Internet can also be used for transmitting information from one brain to another.


In their study, the research team used four volunteers, ranging in ages from 28 to 50. One of those participants became the sender and wore a brain-to-computer interface in India, while the other three were the receivers and wore computer-to-brain interfaces in France.


Using EEG, the sender sent two words via the brain-to-computer interface, "hola" and "ciao."


The interface translated the messages into binary code and emailed them to France. There, the computer-to-brain interfaces decoded the emails and transmitted them into the receivers' brains via flashes of light at the edge of their peripheral vision.


This light flashed in a series of numerical sequences that the receivers' brains then decoded, allowing them receipt of the message.


But did it work? The answer is "yes." The receivers correctly received the messages 85 percent of the time.


"This in itself is a remarkable step in human communication, but being able to do so across a distance of thousands of miles is a critically important proof-of-principle for the development of brain-to-brain communications," says Pascual-Leone. "We believe these experiments represent an important first step in exploring the feasibility of complementing or bypassing traditional language-based or motor-based communication."


Other studies have used EEG for brain-to-computer and computer-to-brain interfaces, but this is the first time that researchers have linked human brains and allowed them to directly communicate with each other.

Using your brain as the modem? Kinda.

Not exactly lightning fast, mass communication, but hey... even the Wright Brothers had several models before something flew.

Scientists get closer to digital telepathy transmit words without computer interface

Posted on Sep 5 2014 - 11:49am by Dana Lindahl

Scientists were successful in sendin information from one brain to another without the use of computer interface. This ground breaking experiment used simple words like ‘ciao’ and ‘hola’. The subjects of the experiment were located 5000 miles apart in India and France. Four healthy participants, aged 28 to 50, participated in the study.
The research was led by experts at Harvard University and was conducted without any invasive surgery on the subjects. The study shows technology can be used to transmit information from one person’s brain to another’s even, as in this case, if they are thousands of miles away.

The subjects wore a wireless internet-linked electroencephalogram or EEG and thought of the words ‘hola’ and ‘ciao’. These words were transmitted using robot-assisted and image-guided transcranial magnetic stimulation (TMS) technologies. The subjects experienced this as flashes of light in their peripheral vision, called phosphenes.

The study is published in the journal PLOS ONE. The aim for the research was to find out whether 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.
Alvaro Pascual-Leone, from the Beth Israel Deaconess Medical Center (BIDMC) and Professor of Neurology at Harvard Medical School, says in the study, “One such pathway is, of course, the internet, so our question became, ‘Could we develop an experiment that would bypass the talking or typing part of internet and establish direct brain-to-brain communication between subjects located far away from each other in India and France?’
Pascual-Leone and Giulio Ruffini and Carles Grau led a team of researchers from Starlab Barcelona, Spain; while Michel Berg, led a team from Axilum Robotics, Strasbourg, France.

The scientists believe that this research will open new opportunities in communications. More detailed study in this filed, will help communication with stroke patients.
