Nicole Rust, neuroscientist and author of Elusive Cures, argues for reframing the brain as a complex, feedback-driven system. She compares brains to weather systems and explores why linear, single-target approaches fail for psychiatric and neurodegenerative disorders. They discuss serendipity in drug discovery, landscape models of neural activity, and how large-scale recordings plus AI could reshape neuroscience research.

Episode notes
Limits Of Reductionist Framing
- Neuroscience has amassed many facts but still struggles to solve whole classes of disorders like psychiatric illness and neurodegeneration.
- This suggests our current framing and metaphors for the brain may be insufficient and need rethinking.
How Ritalin Got Its Name
- Many effective drugs were discovered serendipitously long before modern brain science explained their mechanisms.
- Nicole Rust recounts that Ritalin was named after the developer's wife Rita because he bought it to improve her tennis game.
Antidepressant Discovered By Accident
- The first antidepressant emerged from TB trials when patients became unexpectedly joyous.
- Nicole Rust describes iproniazid's discovery as a clinical accident that led to the first antidepressant.
