I thought this was an Jepsen-style article on some distributed systems at first.
Who says it isn't? ;)
Split Brain Does Not Lead to Split Consciousness

#22I'm not sure that this proves that there's a single consciousness. There may be a second consciousness that is receiving some information about observations from the other hemisphere.
I can't prove you don't have two consciousnesses either, or maybe we all do and just don't notice.

You can't even prove GP has one!

#27If you just learned that "Split Brain" was thing, I recommend watching this video by GPGrey, one of the best educational channels on YouTube:

"Virtually all"? "Perhaps 1 bit per second"? Is it definitive that the corpus callosum accounts for exactly 100% of hemisphere communication? I am too skeptical that the brain could be that simple.

Seems like a contradiction of the assumption that they are "completely insulated". Overall I'm pretty skeptical of the notion that the two sides have "virtually no" connectivity and are "completely insulated" from each other, because of a mere corpus collosotomy. Does anyone else find this to be strange?
Edit: According to another comment "anterior commissure and posterior commissure" regions can still communicate some signal.

#29How does a brain split operation work exactly? Do they put a barrier between the two halves? Otherwise, I would expect that signals could still propagate: cut two nerves, then push them together, and I can imagine that a signal can still pass through; if not always, then in a percentage of cases.
exaclty my thoughts, it seems a bit strange to claim "completely isolated" and "virtually no" communication.

If only....
Getting neurons to regrow or fuse, particularly in the central nervous system, is one of the biggest open challenges in neuroscience. If it were actually that easy, spinal cord injuries would be a thing of the past.
