It was probably only a matter of time, but a high technology computer researher man by the name of Adam Wilson has been using his brain waves to use social networking site Twitter, no hands just thinking with brain.
In the biomedical engineer's first tweet on his Twitter page, Adam Wilson wrote: "SENT FROM BCI2000" and soon after "USING EEG TO SEND TWEET"
Some have compared the brain wave Twitter moment to a modern equivalent of Alexander Graham Bell's "Mr. Watson, come here. I want to see you." message
Adam Wilson is a biomedical engineering doctoral student at the University of Wisconsin-Madison and says he is more interested in the human application side of the technology rather than simply sitting at his desk all day an Twitting without hands.
The computer technology system works by monitoring electroencephalography – or EEG – which is the electrical activity produced on the scalp by the movement of neurons within the brain.
The user of a the BCI wears a cap fitted with electonic readers detecting signals sent out via thoughts. The BCI-Twitter set-up contains an onscreen alphabet.Users select letters as they flash in turn, and when the letter that the user wants to type flashes, the system detects a spike in their brain activity, and selects that letter.
A reserach assitant explained: "If you're looking at the 'R' on the screen and all the other letters are flashing, nothing happens. But when the 'R' flashes, your brain says, 'Hey, wait a minute. Something's different about what I was just paying attention to.' And you see a momentary change in brain activity."

"You have to press a button four times to get the character you want," he said of texting. "So this is kind of a slow process at first," Adam Wilson said.
