New Scientist is carrying this article detailing some new discoveries about brain structures and language. By studying people with a new type of scanner, scientists have confirmed the involvment of a third area of the brain in language processing. Called "Geschwind's territory", it joins the better-known Broca and Wernicke areas long understood to be involved in language.
At least as interesting is the fact that lower primates also share this construction. The primary differences seem to be related to the strength and type of connections in humans.
