Detailed Description:

Autism is a developmental disorder affecting approximately 60/10,000 individuals. It is characterized by social and language deficits and repetitive behaviors/restricted interests. Functional imaging is becoming a very useful tool in trying to understand the neurobiology of autism. Oxytocin is a hormone produced by the brain to assist with labor and lactation. Recent evidence suggests that it may be involved in social attachment and in repetitive behaviors. In this project, we will study how oxytocin changes the way the brain of autistic adults processes faces, and deals with response inhibition (the ability to interrupt ongoing responses should they prove ineffective or interfering with attaining a goal). There is currently no functional imaging data assessing the effect of oxytocin on the brain. We will explore the activation patterns in response to oxytocin across circuits involved in social cognition (face fusiform area) and response inhibition (caudate, orbitofrontal and dorsolateral cortex) by administering a specific fMRI task activating those circuits before and during an oxytocin infusion. We will also explore the effect of oxytocin in these areas by administering specific cognitive testing not associated with fMRI before and during oxytocin infusion.
