Full Idea
It seems that after a massive stroke or surgical resection, a conscious human being is rapidly "resynthesised" or reunified within the limits of a solipsistic universe that, to outside appearances, is warped and restricted.
Clarification
A 'solipsistic' world is (here) a deeply private one
Gist of Idea
A conscious human being rapidly reunifies its mind after any damage to the brain

A Reaction
Note that there are two types of 'unity of mind'. This comment refers to the unity of seeing oneself as a single person, rather than the smooth unbroken quality of conscious experience. I presume that there is no point in a mind without the first unity.
