Scientists use brain activity analysis to reconstruct words heard by test subjects

Last September, scientists from the University of California, Berkeley announced that they had developed a method of visually reconstructing images from peoples' minds, by analyzing their brain activity. Much to the dismay of tinfoil hat-wearers everywhere, researchers from that same institution have now developed a somewhat similar system, that is able to reconstruct words that people have heard spoken to them. Instead of being used to violate our civil rights, however, the technology could instead allow the vocally-disabled to "speak."
