The brain has a model—an over arching one. At best is can be said the entire brain. Now, that model includes both hemispheres. Redundancy for one, but also just too may things to do and the need to many clusters of neurons. It is still true for edge cases like you said—in that case, when there is a severed corpus callous, the model is still there. You’ve just severed the highest level connection—a physical act that doesn’t change he fact that the brain has a model it is working with.

Huh? How is the model ‘still there’ for someone with a severed Corpus callosum?
As far as I’m aware it doesn’t grow back within a normal human lifespan...
