“Welcome to the Mind-Meld: Our Future of Brain-to-Brain Communication”

plugged-in-brainThe brain-to-brain interface experiment of UW CSE’s Rajesh Rao continues to attract extraordinary attention.

Discover features an in-depth explanation of the experiment and its implications, here:

“Finally, in August 2013, University of Washington scientists Rajesh Rao and Andrea Stocco succeeded in making one leap everyone was waiting for: A human-to-human brain-to-brain interface. By strapping one person into a non-invasive EEG helmet, and strapping the second into a transcranial magnetic stimulation (TMS) helmet, the researchers mind-melded themselves – for the sake of science.

“The experiment went like this: Rao and Stocco sat across campus from one another, watching the same video game. Rao, wearing an EEG helmet, was at the controls – but instead of using his hand to hit the spacebar to fire, he simply imagined moving his hand.

That helmet converted the signal into a burst of magnetic stimulation delivered to the precise region of Stocco’s motor cortex that controlled his right hand. Stocco’s hand would then twitch involuntarily, tapping the spacebar and (sometimes) scoring a hit in the game.”

Science focuses on the implications, here:

“Restoration of normal function has driven development of devices such as cochlear implants for deafness, deep-brain stimulators for Parkinson’s disease, and bionic eyes for the blind, but there has long been a fascination with using similar technologies to “neuroenhance” healthy individuals, helping them control emotions, improve memory and cognition, and even communicate wordlessly with others …”
