Marsupials have no corpus callosum. However, I think (but I may be wrong)
that this reflects their highly undeveloped neocortex. So I don't think
that cutting the callosum in an animal with a well-developed neocortex is
analogous to "marsupializing" it. Seems like the appropriate term (but a
little unwieldy on the tongue) is callosotomy.
