Studies at the University of Montreal Centre for Excellence in Pervasive Development Disorders: In the autistic brain, it appears that more brain resources are concentrated in areas associated with visual detection and identification. By comparison, fewer brain resources are concentrated (and regions show less activity) in areas used to plan and control thoughts and actions. Put another way, the autistic brain exhibits more activity in the temporal and occipital regions and less activity in the frontal cortex as compared with non-autistic brains. The stronger engagement of the visual system, whatever the tasks, is believed to be the first physiological confirmation that enhanced perceptual processing is a core feature of neural organization in autistic brains.
