Talking of Autism....

...as I was recently in another post, I think they go into screaming fits because they lack the internal censor mechanism of ordinary people. Sensory input, unfiltered, then becomes unbearable to them, much like my migraines/TLE does. Like Huxleys Renee, it has all become horribly overwhelming. Like a glass shattering, the outside (atmosphere) pours in as though I was a colonist living in an Earth type environment bubble on another planet. I'm killed (overwhelmed) by its foreigness (The light is too bright. the sound is too loud - touch makes me cringe, smell makes me want to vomit and if I could eat, I'm sure taste would do the same.

I remember reading somewhere that the brain isn't there so much to process information as to censor it. This would explain Aspergers Syndrome sufferers difficulty with incoming sensory data and ordinary peopes ability to handle it.

I think Kim Peak (The character 'The Rain Man' was based on) is unique in this respect, in that having a bridge between both sides of the brain, means he doesn't have overwhelm problems.
