352 | Bing Brunton on Connecting the Connectome to the Body

Bing Brunton
Show Notes

Sean Carroll talks with neuroscientist Bing Brunton about the connectome—the complete wiring diagram of neural connections in a brain—and how recent work on the fruit fly connectome is helping us understand how neural circuits translate into bodily behavior. The conversation explores what the connectome tells us about how brains work, the gap between knowing connections and understanding function, and where connectomics research is heading.

Curious

•
Reductionism Has Limits: Structure Doesn't Explain Function
Even complete knowledge of neural connectivity is insufficient to explain how brains produce behavior—function emerges from the interplay of structure, dynamics, neuromodulation, and embodiment.

Novel

•
Connectome-to-Behavior Bridge
The key frontier in connectomics is mapping how neural circuits—defined by their connectome—connect to and guide bodily behavior.

Highlights

•
The Connectome as Foundation, Not Answer
The connectome—the complete wiring diagram of neural connections—is a crucial first step toward understanding how brains work, but it's far from the final answer.

•
Fruit Fly Connectome as Model System
The complete fruit fly (Drosophila) connectome, now mapped, offers an unprecedented opportunity to study how neural wiring produces behavior in a relatively simple but behaviorally rich organism.

Editorial

•
Computational Biology Bridges Connectomics and Behavior
Understanding connectomes requires deep integration of experimental neuroscience, data science, and computational modeling—skills rarely housed in a single lab.
