Science or Science Fiction? CBS Article on Scientists who are working to decode words from brain signals

(CBS, February 1, 2012) " "This is huge for patients who have damage to their speech mechanisms because of a stroke or Lou Gehrig's disease and can't speak,' Dr. Robert Knight, professor of psychology and neuroscience at UC Berkeley, said in a written statement. "If you could eventually reconstruct imagined conversations from brain activity, thousands of people could benefit."

For the study, published in the Jan. 31 issue of PLoS Biology, the scientists input electrodes into brain surgery patients, and then read them a single word. They tested two computer methods of decoding brain waves, but one method was far superior, they found."
