Essentials: The Neuroscience of Speech, Language & Music | Dr. Erich Jarvis

About this video

In this Essentials episode, Dr. Erich Jarvis discusses the neuroscience of speech, language and music. Dr. Jarvis argues there is no good evidence for a separate language module; instead, he describes a speech production pathway with built-in algorithms for spoken language and an auditory pathway for understanding it. He explains that this production pathway is specialized to humans, parrots and songbirds, which is why dogs can understand many words but cannot speak. Dr. Jarvis links speech circuits to neighboring gesture circuits and describes genes involved in axon guidance that, when turned off, allow speech connections to form. He also argues from personal experience that movement such as dancing helps keep his thinking and cognitive circuits in tune.

Key takeaways

• Dr. Jarvis argues against a separate language module, describing speech production and auditory pathways with built-in language algorithms.
• Dr. Jarvis explains that dogs can understand several hundred words but lack the specialized speech production pathway.
• Dr. Jarvis describes gesture and speech circuits as adjacent and evolutionarily related.
• Dr. Jarvis reports that turning off repulsive axon-guidance genes allowed speech-circuit connections to form in the species studied.
• Dr. Jarvis argues that regular movement, such as dancing, helps keep cognitive circuits in tune as people age.
