A problem with comparing split-brain patients to neurologically-intact
persons is reorganization of the "split" brains. The patterns of
hemispheric interaction after callosotomy are likely to be quite different
than before the operation. The subcortical interhemispheric pathways
may pick up some of the slack that the callosum would have handled (not
nearly as much though).
