Researchers have made a breakthrough in the fight against autism, by identifying subtle deficits in the brains of people with autism spectrum disorder (ASD) that they say could help more precise diagnoses and possibly improve treatment of ASD.
Scientists at the Baylor College of Medicine, Houston, discovered characteristic patterns of brain activity in people with ASD that reflect an inability to perceive themselves as social creatures.
For the study, P. Read Montague and colleagues asked groups of high-functioning people with ASD and normal people to play a “social trust” game as their brains were scanned using functional magnetic resonance imaging. In this widely used imaging technique, harmless magnetic fields and radio waves are used to plot brain flow in brain regions, which reflects brain activity.
