Here's a rare beast: an article that is careful with the phrase "mind reading." There's a lot of hype sludge out there about the use of fMRI for the sake of reading minds. If only.
Greg Miller does a nice job teasing apart the brain scanning from the mind reading. Well done, mate.
“In a sense I think it is a form of mind reading, because the computer algorithm doesn’t know what the person saw,” Chun said. The scans and the algorithms can’t yet reconstruct any old image that pops up in someone’s mind, though. “The step that has to happen next is doing this with imagined faces or faces recalled from memory,” Chun said. “Then it would be true mind reading.”
