Ability to Learn New Words Based On Efficient Communication Between Brain Areas That Control Movement and Hearing

The average adult's vocabulary consists of about 30,000 words. This ability seems unique to humans as even the species closest to us--chimps--manage to learn no more than 100. It has long been believed that language learning depends on the integration of hearing and repeating words but the neural mechanisms behind learning new words remained unclear. Previous studies have shown that this may be related to a pathway in the brain only found in humans and that humans can learn only words that they can articulate. more
