Essentials: The Neuroscience of Speech, Language & Music | Dr. Erich Jarvis
Andrew Huberman
Apr 23, 2026
Episode description
In this Huberman Lab Essentials episode, my guest is Dr. Erich Jarvis, PhD, a professor and Head of the Laboratory of Neurogenetics of Language at Rockefeller University and an investigator at the Howard Hughes Medical Institute (HHMI). We discuss the brain circuits and genes underlying spoken language and why the ability to learn and produce vocalizations is extraordinarily rare in the animal kingdom. We also explore why song likely evolved before language, how gesture and movement share deep neural roots with speech, the neurobiology of stuttering, why childhood is the optimal window for language acquisition, and how physical movement — including dance — may help preserve speech and cognitive function across a lifetime.

Mindsip insights from this episode:
Acknowledge Neanderthals' spoken language through genetic evidence
Based on genetic data from fossils, Neanderthals had the same gene sequences involved in speech circuits as modern humans, suggesting they possessed spoken language.
Engage in movement to maintain cognitive sharpness
To stay cognitively intact into old age, you must consistently engage in physical movement like dancing or walking, as the brain circuits for movement and cognition are interconnected.
Protect speech circuits from cellular stress
Neurons in speech pathways have more neuroprotective proteins because controlling the larynx requires them to fire much faster, creating more potential cellular stress.
Turn off genes to unlock speech evolution
The evolution of speech involved turning off specific genes that normally prevent certain neural connections, allowing new, crucial pathways for vocal control to form.
Retain diverse sounds to ease adult language learning
People who learn multiple languages as children find it easier to learn more as adults not because of greater brain plasticity, but because they've retained a wider range of sounds.
Explore singing as the precursor to human language
A leading hypothesis is that human language first evolved for emotional expression through singing, and only later was adapted for abstract, semantic communication.
Connect speech evolution to body movement circuits
The brain pathways that control speech are thought to have evolved from the brain pathways that control body movement, which is why we often gesture unconsciously while talking.
Engage brain pathways while reading silently
When you read silently, your brain sends signals to your speech pathways to 'speak' the words, and then to your auditory pathways to 'hear' them in your head.
