Watching Thoughts ...

Technology Review has an interesting article called Watching a Single Thought Form in the Brain in which researchers at the University of New Mexico show that when "a volunteer thinks of a word, researchers detect brain activity in Broca's area (yellow arrow), a part of the brain involved in language."

Sort of mind-reading, but not quite. Still if this fMRI technique evolves, it could be used for clinical diagnoses and to help researchers understand how we learn.
