- Great new review on neural manifolds by @juangallego.bsky.social and @mattperich.bsky.social. Amazing read. Lots of intuition and examples. Great synthesis of why manifold structure pops up everywhere in neuroscience, from motor control to cognitive tasks. www.nature.com/articles/s41... 🧠🧪 1/3
- Brain structure and behavior give rise to manifolds. But what about the environment? Either through statistical learning or just similar inputs leading to similar representations: the input/task will shape the manifold, no? Linear track → linear representation. Circular color space → ring. 🧠🧪 2/3
- And for me the big question is: What about representational drift? 😄 Manifolds can be mapped, but individual neuronal responses change. That’s neat, but how does it make sense? How can perception stay stable if the neurons keep changing? I’m sure manifolds will help us understand that too… 🧠🧪 3/3Aug 4, 2025 19:27
- There's a long and fun conversation to be had here 🙂. But I agree, the "many-to-few" nature of neurons to manifolds allows considerable drift in single neuron activity without changing the manifold. Important in next steps to find out when, and how, neural drift changes manifold-level properties!
