Reposted by Malcolm CampbellTim Behrens @behrenstimb.bsky.social · 23/03/2026What are the systems in neuroscience that we really have something that we can call “explanation” at all relevant levels, other than reflexive feed-forward like circuits. Here are a few that I would argue are getting there. Obviously not complete explanations but genuinely satisfying. 17427
