Attractors are usually not mechanisms - new blog post: open.substack.com/pub/kording/...
Attractors are usually not mechanisms
The mathematical objects can not be. And the "attractor models" have not been established as mechanisms in mammals

Konrad Kording argues that the best way to understand the brain may be to read its wiring directly rather than infer it from the outside.

Want to bet all cells do gradient descent?
If I say brains do gradient descent I must posit that cells do so, too.

It was to see some many friends in Philadelphia for the @comm4rigor.bsky.social meeting a couple of weeks ago. Together we are developing free online materials for researchers interested in doing rigorous science.

The first units are coming soon at c4r.io.
