"So basically the hardware of the brain out paces the software of the brain. This explains a lot and will probably lead to better treatments for autism in the near future."
This seems to me to square with what Temple Grandin (a high-functioning autistic woman) has to say about her early childhood: that she was very much over stimulated by sensory inputs that are part of the everyday environment, that she couldn't stand various sounds and physical sensations; they were tormenting to her.way too much for her to handle.
My brother, who is non-verbal, will sometimes hold his hands over his ears. He can't communicate why with us, but I suspect that he's experiencing something like what Temple describes.
