A literature search is what you need to do.  I don't know how many
commisurotomies have been performed, but most of the literature I'm
familiar with concerning split-brain patients studies the same small
group over and over -- Gazzaniga has gotten quite a lot of mileage out
of patient "J.W." especially.  Gazzaniga has a chapter in the book he
meta-edited, "The Cognitive Neurosciences", that reviews the conceptions
of consciousness that came out of work with split-brain patients over
several decades of research.  You might want to start there.
