@s8n it primarily happens in a small part of the neocortex (the hippocampus.)

there are some weird properties with learning rules though. had a paper on friday where they were getting 95% on MNIST purely through plasticity rules and no actual learning engine.

there seems to be some amount of self-organization with a feedback governor of some kind. but we know mammals can't learn shit when the hippocampus is broken, so that seems to be where the feedback governance is being emitted from.

(the prefrontal sends a lot of stop signals though.)
