Reading Brain Waves… literally [via wtop]:
Armed with a $4 million grant from the Army, scientists are studying brain signals to try to decipher what a person is thinking and to whom the person wants to direct the message.
The project is a collaboration among researchers at the University of California, Irvine; Carnegie Mellon University; and the University of Maryland.
The scientists use brain wave-reading technology known as electroencephalography, or EEG, which measures the brain’s electrical activity through electrodes placed on the scalp.
It works like this: Volunteers wear an electrode cap and are asked to think of a word chosen by the researchers, who then analyze the brain activity.
