Split-brain double identity
My character have a split brain (severed connection between left and rigt hemispheres).
What is unique about his case is that not both hemispheres have the same identity any more.
From what I understood, each hemisphere is a brain of its own (mostly), this is evident from the patients who underwent Hemispherectomy and recovered to function almost normal.
His right hemisphere (doesn't control speech), now had so many different experiences because the researchers fed his left eye and ear different information for long time, which led to it having differeing identity.
Now the left hemisphere that control speech stopped covering up for the right side. And instead became aware of it, now the person can hold conversations with the different and judgy right hemisphere.
I have quite limited understanding of what identiy really means, and how do you actually "feel" a different identity in your own head, because you don't hear it, you just know these ideas is not yours, but the ideas are so structured it is like a conversation.
What problem this scenario will have that prevent this from working?
