Actually in his autobiography (Recollections of My Life - pp.
470-475), Ramon y Cajal discusses what he feels are the reasons for
the crossed nervous system. I will refer you to this book and his
original articles on the subject rather than trying to explain it here
and screwing it up.  As I recall there were many papers that followed
from this theory so you should be able to find more on it.
