( In two revolutionary studies brain sci...)Study Finds That Brain Areas Of People With Autism Do Not Work In Coordination,Health

In two revolutionary studies, brain scientists at Carnegie Mellon University and the University of Pittsburgh have discovered that in autistic people// the method by which their brain process information is the basic anatomical difference differentiating them from normal people.

It was explained that in studies that were conducted previously it was shown that a reduced amount of coordination existed among people with autism, and also that there was a decrease in the size of corpus callosum, which is the white matter that acts as a cables to wire the various parts of the brain together. The new research shows for the first time has shown that the abnormality in synchronization is related to the abnormality in the cabling. Which could suggests that the connectivity among brain areas is probably the primary problems in autism. The researchers have also found that people with autism think using pictures, meaning that they tend to increasingly use those parts of the brain that deal with descriptions, even when completing tasks that would not normally call for visualization.

"Human thought is a network property. You think not with one brain area at a time, but with a network of collaborating brain areas, with emphasis on collaborating. In autism, the network connectivity (the bandwidth) through which the areas communicate with each other may be limited, particularly in the connections to the frontal cortex, limiting what types of networks can be used," said Marcel Just, co-author of the studies and director of Carnegie Mellon's Center for Cognitive Brain Imaging.

Both studies focused on people with autism who have normal IQs. In one study, the researchers used functional magnetic resonance imaging (fMRI) to view which parts of the brain were activated in people with autism compared to a control group of normal participants while completing the Tower of London task. In a Tower of London task, participants must -- in a set number of move
