Mirror Neurons with Michael Arbib (BSP 39)

Episode 39 of the Brain Science Podcast is an interview with Dr. Michael Arbib from the University of Southern California.  Dr. Arbib's work with functional brain imaging has established the presence of mirror neurons in the human brain.  In our interview, we focused on the role of mirror neurons in imitation and language.  In particular, I questioned Dr. Arbib about the Mirror System Hypothesis (MSH) of Language Evolution that he proposed in 1998 with Giacomo Rizzolatti.  We also explored how this hypothesis diverges from the universal grammar proposed by Noam Chomsky.  Dr. Arbib also shared his enthusiasm for future research and we talked about the special challenges caused by the interdisciplinary nature of modern neuroscience.

The Evolution of Language (BSP 30)

Episode 30 of the Brain Science Podcast is a discussion of The First Word: The Search for the Origins of Language, by Christine Kenneally.  We focus mostly on the first part of the book, which tells the story of how the study of language evolution has grown from almost a banned subject to a new field of inquiry called evolutionary linguistics.  We also reflect on how recent findings in neuroscience like the importance of plasticity are influencing the field.
