First human brain-to-brain interface

Researchers at the University of Washington have seemingly accomplished a human-to-human brain interface in an experiment. The basic setup for the experiment was that one professor would attempt to transmit brain activity across campus through the internet to stimulate the brain of another professor. The professor sending the information wore a cap with electrodes attached to an EEG machine, to read and record his brain activity, while he played a simple game where he would imagine moving his hand to hit the fire button without moving his hand. The receiving professor wore a hat with a transcranial magnetic stimulation coil put right over his left motor cortex which would induce a current in the part of the brain responsible for hand movement. As the sender thought of moving his hand the receiver involuntarily moved his hand, activating the fire button.

The notion of truly connecting the minds of two human beings directly, albeit through a relatively simple thought, is astounding as the idea has seemed straight science fiction to me for so long. The future development of methods and technologies in this field will most likely hold some heavy implications as language barriers could be fractured and communication with debilitated people could be an easier process. Even methods of teamwork, learning, and problem solving in general could eventually be greatly improved upon with future advances in human brain-to-brain interfaces.
