The Huberman Lab Podcast discusses neuroscience: how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health. We also discuss existing and emerging tools for measuring and changing how our nervous system works. Dr. Andrew Huberman is a tenured Professor of Neurobiology and Ophthalmology at Stanford School of Medicine. His laboratory studies neural regeneration, neuroplasticity, and brain states such as stress, focus, fear, and optimal performance. For more than 20 years, Dr. Huberman has consistently published original research findings and review articles in top-level peer-reviewed journals, including Nature, Science, Cell, Neuron, and Current Biology. He is a regular member of several National Institutes of Health review panels and a Fellow of the McKnight Foundation and the Pew Charitable Trusts. Dr. Huberman regularly consults for technology development companies, professional athletic organizations, and various units of U.S. and Canadian Special Operations.
Dr. Eddie Chang: The Science of Learning & Speaking Languages | Episode 95
My guest is Eddie Chang, MD, a neurosurgeon and professor of neurological surgery at the University of California, San Francisco (UCSF) and the co-director of the Center for Neural Engineering & Prostheses. We discuss the brain mechanisms underlying speech, language learning and comprehension, communicating human emotion with words and hand gestures, bilingualism and language disorders, such as stuttering. Dr. Chang also explains his work developing and applying state-of-the-art technology to decode speech and using that information and artificial intelligence (AI) to successfully restore communication to patients who have suffered paralyzing injuries or “locked in syndrome.” We also discuss his work treating patients with epilepsy. Finally, we consider the future: how modern neuroscience is overturning textbook medical books, the impact of digital technology such as smartphones on language and the future of natural and computer-assisted human communication.
