On Humans Can the Brain Understand Itself? The Glories and the Limits of Neuroscience ~ Matthew Cobb
Oct 17, 2025
Joining the discussion is Matthew Cobb, a renowned neuroscientist and author of 'The Idea of the Brain,' who dives into the intriguing history and limits of neuroscience. He elaborates on Galen's groundbreaking pig demonstration and the emergence of brain localization theories. Cobb discusses how drug discoveries in the 1950s shaped public perception, while highlighting the enigmatic nature of brain plasticity. He reflects on whether we can crack the neural code and shares insights on how studying the brain has influenced his understanding of humanity.

Episode notes
Galen's Pig Demonstration
- Galen demonstrated brain control of voice by stopping a pig's squeal after pressing its brain during a public dissection.
- The dramatic demo failed to overturn prevailing heart-centered beliefs despite its immediacy.
Anatomy Reveals Brain Complexity
- Vesalius's detailed brain anatomy showed the organ's staggering complexity and undermined simple heart-centered theories.
- Complexity made the brain a more plausible seat of thought compared to the pump-like heart.
Broca's Stroke Observations
- Paul Broca observed stroke patients who lost speech and found consistent lesions in the left frontal brain region.
- This clinical evidence helped establish localization of function despite earlier resistance.
