A 29-year-old patient was able to answer yes-or-no questions by visualizing specific scenes the doctors asked him to imagine. The two visualizations sparked different brain activity viewed through a scanning machine.
“We were stunned when this happened,” said one study author, Martin Monti of Medical Research Council Cognitive and Brain Sciences Unit in Cambridge, England. “I find it literally amazing. This was a patient who was believed to be vegetative for five years.”
