The Science of Learning & Speaking Languages | Dr. Eddie Chang

About this video

Dr. Eddie Chang, chair of neurosurgery at the University of California, San Francisco, joins Huberman to discuss the science of learning and speaking languages. Dr. Chang’s work covers speech and movement disorders, epilepsy, and devices that allow people with locked-in syndrome, who cannot speak or move, to communicate through computers. They discuss critical periods when languages are learned with great ease, bilingualism, how the brain controls the muscles of speech, and stutter. In the middle excerpt Dr. Chang explains his group’s direct recordings from the human brain surface during epilepsy mapping, with millisecond resolution, revealing complex patterns in Wernicke’s area as people hear words and sentences, and individual sites responding to particular features of speech sounds, which his team has spent a decade decoding.
