In today's episode, Dr. David Pesetsky of the Department of Modern Languages and Linguistics at MIT talks to Adam about the similarities shared by all human languages. Despite differences in words and their arrangement into phrases and sentences, languages vary in systematic ways around the globe. Similarities between languages have led some researchers to speculate that something inherent in the human brain is biologically responsible for language; consequently, their research focuses on the language acquisition of children for clues. Advances in neuroscience and brain imaging may ultimately indicate the biolgical basis for language. Join Adam as he learns about the universal nature of language and how future research may finally reveal how the brain processes and supports human expression. [03:56]
