Description: People with autismautism may not daydream like most people do. A new study suggests that the brain activity found in most people while at rest or "daydreaming" is absent in people with autism. Researchers say the brain regions normally active while at rest or daydreaming are important for processing emotional and social issues. The lack of this activity in the brains of people with autism may help explain some of the antisocial behavior and emotional problems found in people with the disorder.
