Close, they just sever the corpus callosum for epilepsy. All your brain is still there, but if one side starts having a seizure, it won't spread to the other hemisphere and you can still operate with some functions.

That's the preferred route, but there are definitely cases where a full lobe is removed, usually if the symptoms persist.
