I used to have a girlfriend who was studying a type of science in college. She was really interested in it, and it actually sounded pretty cool. It had to do with the way people reproduce sounds with their mouths, based on how they heard it. It also studied parts of the brains where language was developed. I talked about how people who learn to languages at birth use only one part of their brain, but those who learn a language later in life use two parts. I'm sort of babbling, but I've forgotten what its called. Anyone know?
