Decoding Language from Brain Recordings

Science non-fiction: a badass lab at the, soon to be PAC 12 school, University of Utah just published a paper on discriminating between words from the part of the brain that controls face movement. This could allow locked in patients like the especially stylish one that wrote The Diving Bell and the Butterfly to communicate with the outside world using their thoughts alone. Here's a picture of the recording technology: The researchers tried to decode from the part of the brain that has been attributed with language comprehension, but it wasn't active while the patient was speaking, only while he was listening to the researcher's talk in between sessions:
Then when the patient started talking they could record the brain signals from the face motor area and discriminate between words the patient said based on the brain signals alone. Wow.
