Unique patterns of neural communications found in brains of children with autism

Now consider the same center in a child with an autism spectrum disorder (ASD). At a time different parts of the brain are supposed to be talking to each other or working together, this traffic--the communication between different regions of the brain--takes unexpected exits and detours for no apparent reason.

A team of San Diego State University researchers, studying MRI scans of school-age children's brains, found just such unique patterns of neural communication involving the amygdala, the area of the brain responsible for processing social information. In children with ASDs, the amygdala connections with other parts of the brain proved to be weaker with some regions --and stronger with others--when compared with typically developing children of the same age.
