Consciousness: not split in split-brain patients (General)

QUOTE: "And there’s more. While the previous model provided strong evidence for materialism (split the brain, split the person), the current understanding seems to only deepen the mystery of consciousness. You split the brain into two halves, and yet you still have only one person.
How does a brain, consisting of many modules, create just one person? And, how do split-brainers operate as one when these parts are not even talking to each other?"

DAVID’s comment: More proof that consciousness has no true basis in the idea that it is being produced by the brain. The brain receives the mechanism of consciousness and uses it.

dhw: This is a fascinating discovery. It’s based, though, on an almost throw-away statement that slightly bothers me:
“But without the corpus callosum the hemispheres have virtually no means of exchanging information.”
Why “virtually”? If there is any means at all of exchanging information, how do we know the extent to which it can be operative? As I say, I’m only slightly bothered by it, and the source and nature of consciousness and the force that unifies ALL our cell communities, including those of the brain, remain an endlessly intriguing mystery which we shall keep returning to. As usual, many thanks for keeping us so well informed about all the latest findings.

The word 'virtually' implies that there might be an unknown way of communicating. Just covering all possibilities.
