This -- our technology -- is heartpounding!

"The... patient, who had been in a persistent vegetative state for 12 years after a head injury, was able to "answer" in the negative when asked if he was in a supermarket, but affirmatively when asked if he was in a hospital. The patient also gave correct answers to yes-no questions about his name, the researchers reported online in JAMA Neurology.
These "answers" were in the form of increased activity in brain regions that had previously been activated during a training period in which patients were instructed either to count occurrences of the words "Yes" or "No" when spoken to them or to ignore them. Whether or not they counted accurately was not the point -- rather, it was to have them focus their attention on these words.
Then, when the patients were asked a Yes-No question, they were read a series of words that included "Yes" and "No" at different points. Patients' increased attention to either "Yes" or "No" during this exercise served as the response.
"To our knowledge, we show for the first time with functional magnetic resonance imaging that behaviorally nonresponsive patients can use selective auditory attention to convey their ability to follow commands and communicate," Naci and Owen wrote.
"The technique may be useful in establishing basic communication with patients who appear unresponsive to bedside examinations and cannot respond with existing neuroimaging methods," they added."
