Scientist Controls Colleagues Hand Motion via Brain-to-Brain Interface

August 30, 2013, By Sanjeev Ramachandran

Researchers from the University of Washington have taken a leap forward in the study of human brain to brain interface. The first non-invasive human brain to brain interface has been experimentally tested.

One of the researchers, Rajesh Rao, has successfully sent a brain signal via the internet to control the hand motions of his colleague to move his fingers in a keyboard.

The experiment has been conducted using brain recordings and a form of magnetic simulation. Rao sent the impulses to Andrea Stocco, at another part of the Washington University campus, and succeeded in moving Stocco’s finger with the impulse sent from the other side.

The experiment is the first of the kind in human to human interface. Earlier, researchers at the Duke University had demonstrated brain to brain communication between two rats and researchers from Harvard University had demonstrated interface between a human being and a rat.

Stocco has been quoted saying about the experiment that though the internet was earlier the medium to connect computers, it can now be used to connect human brains also.

The experiment was conducted as follows: Rao sat in a lab, wearing a cap with electrodes connected to an EEG machine to read the activity of his brain. Meanwhile, Stocco was sitting in another lab wearing a swim cap marked with the stimulation site for the transcranial magnetic stimulation coil placed directly over his left motor cortex, which controls movement of his hand.

Rao played a video game in the computer, and when he was supposed to fire a cannon at the target, he just imagined that he is moving his right hand over the keyboard. Instantaneously, Stocco moved his fingers over the keyboard, doing what Rao imagined to do.

The new research will pave the way for new experiments and inventions using human brain to brain interfacing.
