A beautiful mind.

Ah yes, I'm sure it is a good movie, and I'd love to see it; maybe I'll get around to renting the DVD some day. John Nash's brain, however, unlike many (actually most SZ patients) was able to rearrange itself, and it does appear that his constant self-thought writing on blackboards at Princeton (where he is now, it seems) helped a bit.

He did go through some rough times however, and while his cognitive loops lost inhibition for some while, he didn't really loose the overall ability--voices in the head are part of cognition mappings at work.
