 No. What's happening here, supposingly, is a person is shown a sequence of simple, black & white images – in this case, the word "N E U R O N", presented in a sequence of block letters – while the machine scans a specific part of the subject's brain activity. Then the machine translates the data gathered from the scan, back into the sequence of images that the person was shown.
