Brain Hack: The idea of being able to read someone else's brain is exciting enough on its own. Now imagine how wonderful it would be to not say a word and still be able to communicate with your fellow human being. Then imagine the Internet serving as a connector for that communication, wouldn't that be great?
These questions arise after recent research conducted by the University of Washington that used a brain-to-brain connection. This process aimed to bring together pairs of participants to play a question-and-answer game by transmitting signals from one brain to another over the Internet.

Let's take a look at the process diagram:
And the process:
A cap with electrodes was placed on Player 1's head.
The signals are read by an EEG (electroencephalogram) system.
This player sees a screen on which there is a "yes" and a "no" with lights (with different pulse rates).
At a long distance (miles away) Player 2 is assisted with a special magnet on the back of his head, which is connected to the EEG system via the Internet.
Player 2 then selects a question from a computer screen. The question is sent to Player 1's screen. Player 1 stares at either the flashing light “yes” or “no.”
This EEG system sends a signal to the magnet.
If the answer Player 1 looked at was “yes”, then the magnet then fires a pulse into Player 2's head which causes a flash of light in the brain.
Really great, isn't it?
Participants were able to guess the correct answer to 72% of the questions. Incorrect answers are judged by many factors, such as a participant being unsure of their answer.

This group is also working on the transmission of brain states — for example, sending signals from an awake person to someone who is sleepy, or from a focused student to someone who is having trouble concentrating!
