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
Split-Brain Patients Reveal Two Minds
- Split-brain surgery for epilepsy revealed distinct behaviors in each hemisphere, sometimes producing conflicting actions.
- Right-hemisphere perceptions can influence behavior without conscious awareness from the left-speaking hemisphere.
Lobster Stomach Defies Full Explanation
- Eve Marder's stomatogastric ganglion is fully characterized yet still resists predictive modeling.
- Even 13 known neurons producing two rhythms defy complete explanation and prediction.
Why Bottom-Up Brain Models Stall
- Complexity limits bottom-up simulation: 30 neurons can be intractable despite modern computing.
- David Marr's levels suggest studying higher-level codes instead of every cellular detail.
