Way back in 1999, Kenji Doya sketched a big picture theory of the brain:
1️⃣The cerebellum is specialized for supervised learning
2️⃣The basal ganglia are for reinforcement learning
3️⃣The cerebral cortex is for unsupervised learning
How does this hold up in 2026? www.sciencedirect.com/science/arti...

From sensory to perceptual manifolds: The twist of neural geometry
The brain uses geometric twists to expand neural dimensionality, thus untangling perception from sensation.

Thank you for having me on BrainInspired, Paul @braininspired.bsky.social! It was such an honor to be on my favorite show—a rare place where we can leisurely talk about manifolds, latent circuits, power laws, and other esoteric ideas, and still be taken seriously in knowing they are all real.
Are manifolds real?
Are latent circuits real?
Tatiana @engeltatiana.bsky.social uses one, infers the other, and says yes to both.
Also, how timescales are different and the same across the entire brain...
