Scientist send 5000 miles away message brain to brain communication from India to France
India to France Distance 5000 Miles Scientist transfer Brain to Brain message successfully India to France
The technology was developed as part of a collaboration between the University of Barcelona in Spain, Axilum Robotics in France, Harvard Medical School and Starlab Barcelona in Spain.
According to the researchers, this is the first time humans have sent a message ‘almost directly’ into each other’s brains.
The researchers used electroencephalography (EEG) headsets which recorded electrical activity from neurons firing in the brain to convert the words ‘hola’ and ‘ciao’ into binary.
In EEG, electrical currents in the brain are linked with different thoughts that are then fed into a computer interface
In EEG, electrical currents in the brain are linked with different thoughts that are then fed into a computer interface. This computer analyses the signal and controls an action.
In the latest study, published in Plos One, researchers decided to replace the computer interface with another brain to receive the signals.
The recent development of brain-computer interfaces (BCI) has provided an important element for the creation of brain-to-brain communication systems, and precise brain stimulation techniques are now available for the realization of non-invasive computer-brain interfaces (CBI).
These technologies, BCI and CBI, can be combined to realize the vision of non-invasive, computer-mediated brain-to-brain (B2B) communication between subjects (hyperinteraction).
In the initial test, the greeting was sent from a volunteer in Thiruvananthapuram, India to Strasbourg, France.
There, a computer translated the message and then used electrical stimulation to implant it in the receiver’s mind.
This message appeared as flashes of light in the corner of their vision.
The light appeared in sequences that allowed the receiver to decode the information in the message.
Researchers then conducted a similar experiment in which thoughts were successfully transmitted from two participants, one in Spain and one in France.
The second experiment resulted in a total error rate of just 15 per cent, with a 5 per cent on the encoding side and roughly 11 per cent on the decoding.
Materials and Methods
Four healthy participants (age range 28–50) were recruited, and their informed written consent was obtained. Of the four subjects, one was assigned to the BCI branch (the emitter - Subject 1) and the other three to the CBI branch of the experiments (i.e., as receivers - Subjects 2, 3 and 4).
