One thing I've been wondering about lately is whether our brains have more than one consciousness arising from it and we are just one of them. In split-brain experiments, it's shown that two independent consciousnesses can exist in the same skull, since they have been physically cut from each other. The predominant assumption is that when both hemispheres are connected, only a unified consciousness arises. Tononi says that in any composite system of consciousness, the component consciousnesses are suppressed and only the highest-level one is active. But what if they're still active and have their own subjective experiences? We won't necessarily see it in other people just as split-brain patients seem like one person until you scrutinize them. And that all consciousnesses will have access to the same memories sort of muddies it up a bit, but it still accounts for different phenomena, including unconscious thoughts, desires, and behaviours; and changes in personality.
