Some interesting new research:

New evidence shows that the brains of adults with autism are "wired" differently from people without the disorder, and this abnormal pattern of connectivity may be responsible for the social impairments that are characteristic of autism.

Using functional magnetic resonance imaging, a team of researchers affiliated with the University of Washington's Autism Center also found that the most severely socially impaired subjects in the study exhibited the most abnormal pattern of connectivity among a network of brain regions involved in face processing.

"This study shows that these brain regions are failing to work together efficiently," said Natalia Kleinhans, a research assistant professor of radiology and lead author of the paper published in the journal Brain. "Our work seems to indicate that the brain pathways of people with autism are not completely disconnected, but they are not as strong as in people without autism."
