Known as the cortex, the neocortex, the cerebral cortex, the cerebrum, the pallium, and the neomammalian brain. "Cortex" means "bark" like on a tree, because this brain surrounds the smaller older ones. We have other "cortexes" that are things that surround other things.

Has four lobes:

They all do lots and lots of things and overlap a lot. They're pretty reprogrammable in that way.
