Longitudinal neurogenetics of atypical social brain development in autism  

Dr. Pelphrey and his colleagues plan to use a specialized brain imaging technique to examine the relationship between variants in the serotonin transporter gene and behavioral difficulties in individuals with autism. The technique, called functional magnetic resonance imaging (fMRI), detects neuronal activity and can focus in on various regions of the brain. The researchers plan to record brain activity in a group of 5-year-old children — half with autism and half typically developing controls — during laboratory tasks that test their ability to understand the intentions of others and cope with frustration. The children will be tracked in the group over a two-year period. The researchers also plan to sequence the serotonin transporter gene in each child to identify those who have the "short" variant, which lowers the gene's expression and has been linked to problems with social interaction in children with autism. The researchers also plan to repeat the brain activity and genetic studies in a group of 25- to 30-year-old adults with autism and healthy controls. Project Status
