Direct brain-to-brain communication has been a long-held ambition of scientists and science fiction fans alike. Recently, University of Washington (UW) researchers brought that ambition a step closer to reality by successfully conducting a direct brain-to-brain connection between pairs of volunteers over the internet by transmitting signals from one person’s brain to another
to directly govern the motions of the receiving person’s hand.
A human test subject in India has emailed the messages "hola" and "ciao" to three other people in France. Doesn't sound too impressive? Well, in this case the words were composed and interpreted using only the brain ... along with some high-tech help.
Brain-to-brain interfacing – it’s previously been accomplished between two rats
, but now it’s been achieved between two humans. Rajesh Rao, who studies computational neuroscience at the University of Washington, has successfully used his mind to control the hand of his colleague, Andrea Stucco. The two were linked via a Skype connection.
Telepathy has long been a subject of controversy in physical and psychological circles, offering the potential for removing the material and sensory walls between individuals, and allowing the direct transmission of information without using any of our known sensory channels or physical interactions. Although true telepathy still appears to be pseudoscience, futurists have long predicted that some form of technologically-based telepathy would eventually emerge ... and, it would appear, it has.
Brain-Computer Interfacing (BCI) is a hot area of research. In the past year alone we’ve looked at a system to allow people to control a robotic arm
and another that enables users to control an ASIMO robot
with nothing but the power of thought. Such systems rely on the use of an electroencephalograph (EEG) to capture brain waves and translate them into commands to control a machine. Now researchers at the University of Southampton have used a similar technique to show it is possible to transmit thoughts from one person to another.
