 Indeed, the apparent split runs still deeper. Between the two hemispheres there seems to be a split in unified consciousness of experiencing, too: Consciousness of doing some experiencing goes with lack of consciousness of doing other experiencing that is going on in the same body. To use a useful metaphor first coined, so far as we know, by Shoemaker, something is not conscious of acts of experiencing going on in its body ‘from the inside’, i.e., on the basis of doing them, while something else is conscious of them on this basis. There seems to be a split in unified consciousness of self, too: Consciousness of oneself as subject on the basis of doing acts of experiencing in that body goes with lack of consciousness of oneself as subject on the basis of other acts of experiencing being done in that body. If so, for many conscious states in these patients, there two instances of  joint consciousness (section 2.1.3),  not the normal one.
