Thanks for this! I love, love, LOVE the scientific study of dissociative disorders. I should have been a researcher, I reckon!

My thoughts:

1. My understanding is that the different patterns observed in brain activity are related to different emotional states, in much the same way that the brain of a normal person will show different activity when they experience different emotions and thought patterns. The difference is, in a dissociative person, that any one
dissociative state will show consistency in the brain patterns whenever they are 'out', whereas in a non-dissocative person the changes in their brain waves between emotional states are more fluid. I guess my point is there aren't 'extra' people in there, but the research on brain waves does show the distinctly separated self states.

2. Don't worry - you're not screwed! You may be hippocampally and amygdalally (?!) 'challenged' but you still are capable of achieving a happy and fulfilling life. Afterall, what's life without a few extra challenges, right? :P
