Man in coma uses his thoughts to tell doctors, ‘I’m not in pain’

Back in 2010, neuroscientists confirmed that it was possible to communicate with some patients locked in a vegetative state by using an fMRI scanner. Though limited, the breakthrough suggested that more meaningful dialogue with patients in a coma could someday be possible. And now, two years later, it has finally happened. A Canadian man in a vegetative state has used his thoughts to tell scientists that he is not in any pain, marking the first time a patient in such a condition has relayed information relevant to their care.
