    A thought experiment:

    For the purposes of this experiment, imagine that the medical knowledge is available to perform this procedure.

    Imagine you have two perfectly healthy individuals: Ben and Fred. For this experiment, the right hemisphere of their brains are removed. They are then placed into the other indivduals skulls, to replace their right hemisphere. Neurons are then stimulated, and make connections to connect the two hemispheres as normal.

    After this procedure is completed, the two wake up.

    Now...

    Who is who? What happened to the original entities of Ben and Fred? Do they still exist? Where are they?

    What does this imply about their identities?

    This is actually a really interesting question. I'll answer properly when I have more time, but what's your personal take on it?

    Ill be honest, im not sure. I think serious emotional and psycological distress is a certainty. But we know from various neuological experiments that the brain has inventive ways of dealing with discrepency.

    I dont think it would result in either subject feeling that they have someone else inside them, or that one personality would dominate the other.

    From the point of view of metaphysics, no, they do not still exist. You've mixed identities (memories, feelings, etc.), the actual matter that composed each individual is no longer identifiable, etc. There is no way in metaphysics remotely capable of making an argument such that there is continued personhood. As it is, even with normal persons metaphysics has a very difficult time trying to argue that there is such a thing as continued personhood from T1 to T2.

    What does this imply about their identities?
    They're new persons. And probably quite traumatized new persons at that. They would likely experience memories as very strange third-person flashbacks. Likely suffer disassociative disorders, perhaps PTSD, etc.

    Their neural pathways for memory recollection would be broken, so their memories would be scattered, on occasion not available on desired recall, likely occasionally experienced involuntarily.

    Considering neurons would never be attached, likely both would become different people, go insane etc.

    Were that possible? People have dominant sides, usually left, so I guess they just develop different traits, but it's whoever owns the dominant side.

    The 'dominant side' idea is a myth. See e.g here
