I'm curious what could happen in the brain of people with dissociative identity disorder?

Dissociative: Identity Disorder (DID) is often the aftermath of severe trauma early on in life. We don't know a lot about the physiology of the brain under these conditions but believe that one aspect of consciousness begins to deal w/life while the rest of it is protected from life, memories repressed. As each aspect develops a function it becomes a "personality." People w/DID can have many of these. Peace
