A psychology researcher has pinpointed regions of the brain that are linked to "ritualistic repetitive behavior" in autistic children -- the insatiable desire to rock back and forth for hours or to tirelessly march in place.
Keith Shafritz, an assistant professor of psychology at Hofstra University on Long Island, compared brain images of autistic children with those of neurologically normal youngsters. He and collaborators at Duke University and the University of North Carolina in Chapel Hill used a form of magnetic resonance imaging to explore sites in the brain.
They reported their findings in the current issue of Biological Psychiatry.
