First direct brain-to-brain communication between human subjects

Via KurzweilAI.netAn international team of neuroscientists and robotics engineers have demonstrated the first direct remote brain-to-brain communication between two humans located 5,000 miles away from each other and communicating via the Internet, as reported in a paper recently published in PLOS ONE (open access).Emitter and receiver subjects with non-invasive devices supporting, respectively, a brain-computer interface (BCI), based on EEG changes, driven by motor imagery (left) and a computer-brain interface (CBI) based on the reception of phosphenes elicited by neuro-navigated TMS (right) (credit: Carles Grau et al./PLoS ONE)In India, researchers encoded two words (“hola” and “ciao”) as binary strings and presented them as a series of cues on a computer monitor. They recorded the subject’s EEG signals as the subject was instructed to think about moving his feet (binary 0) or hands (binary 1). They then sent the recorded series of binary values in an email message to researchers in France, 5,000 miles away.There, the binary strings were converted into a series of transcranial magnetic stimulation (TMS) pulses applied to a hotspot location in the right visual occipital cortex that either produced a phosphene (perceived flash of light) or not.“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 ...
