Researcher Triggers Motion in a Colleague through Brain Signals


In an announcement made by the University of Washington, Rajesh Rao, a researcher achieved the feat of first demonstration of human-to-human brain signaling. On August 12, Mr. Rao wearing an electrical brain signal reading cap prompted a finger-flicking motion in his colleague Andres Stocco, sitting in a lab across campus, which was sent to him by thought.

The video of this demonstration has been put online on the lab teams’ website and shows Mr. Rao wearing an electrical brain signal reading cap and imagining his right finger flicker during an observation of a cannon firing video game. Mr. Stocco, sitting across campus wearing a cap designed to receive magnetic stimulation signals to his brain, received this signal via internet and as described by him felt like having an “involuntary twitch”.

The researchers proceeded with this experiment only after receiving approval from the university’s medical ethics board. They plan to publish the result of this experiment in a scientific journal yet some like Neuroscientist Miguel Nicolelis feel that due to no direct communication of signals between people, it isn’t necessarily a true brain to brain interface, but only one way of achieving it like using a phone signal to trigger a magnetic jolt to the brain.
