"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. > The [previously] established view of split-brain patients implies that physical connections transmitting massive amounts of information are indispensable for unified consciousness > although the two hemispheres are completely insulated from each other, the brain as a whole is still able to produce only one conscious agent 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.
