: Look up "Sperry split brain" in www.google.com. People with

Back in the eighties, there was a nice little book published called _Human
Cerebral Assymetry_ which covered a lot of the findings. Yes, it has
likely been superceeded, but it is addressable and comprehensive to that
point in time. Further, since there is no real reason, for a complete
commisurotomy, it is very rarely done these days. Only small sections
need be severed to control the seizures which would lead to the surgical
The book also discusses some cases of hemispherectomy in young children,
and the effeects on language.
