New Method Allows Scientists to Read Letters in a Person's Brain Scan

It's not exactly "mind reading," per se, but a team of researchers have developed a method through which they are able to determine what letter a person is looking at based on a scan of their brain. Published in the journal Neuroimage, the study includes using an fMRI to scan a person's brain while he or she views a specific image. An fMRI works by determining where in the brain blood is flowing most and has long been used in research designed to determine which brain areas are most active while a person performs a given task.
