don’t see why we shouldn’t apply the same logic to corpus callosotomy. Destroying the major connection (though not the only one: there is also the anterior commissure, posterior commissure, and hippocampal commissure) between the cerebral hemispheres damages the brain; obviously. The parts that have previously cooperated fluently now have a problem to cooperate. The split-brain syndrome is a result of the damage. However, despite that, the split-brain patients typically maintain a unified sense of self and personality, it’s just that some of their information processing systems are disconnected. Which makes it even less likely that in people with intact corpus callosum the two brain hemispheres secretly act as two different personalities.
That reminds me of Descartes’ Error — how Damasio argues that any damage to one system tends to affect the whole, since reason, emotion, and embodiment are deeply integrated. It feels analogous to social systems too: once a channel of integration is disrupted, even if others remain, the total coherence suffers. So yeah, even when split-brain patients seem unified, it’s still a case of partial systemic breakdown.
