Pedantry Alert: > The mantra is "nuclear" or "regional" organization in birds rather than layers in mammals, but the anatomy [0, Fig 4] and electrophysiology [1] abstract this out in similar patterns. Marsupials too! Sort of. Generally, marsupials are mostly close to other mammals in brain structure, but they do have a fair bit less layers and some nuclear structures. Comparative neuroanatomy in vertebrates is, like, super interesting (to me at least). It really goes to show off evolution and how her pressure is really towards more babies - however that needs to be accomplished.
