This project seeks to understand the role that aberrant eye-movements and gaze patterns in ASD may play in the organization of visual processing mechanisms and how the basic retinotopic maps in early visual cortices may develop atypically as a consequence of these anomalies in gaze. The underlying premise is that basic sensory processing anomalies may be related to what at first blush appear to be social deficits e.g. not looking a peer in the eye during communication. Work using high-density event-related potentials ERPs has revealed atypical visual adaptation functions in Autism, again pointing to basic sensory processing anomalies in this population. Our research team is developing precise retinotopic mapping procedures using functional neuroimaging, procedures appropriate for detailed mapping of early visual maps in the often challenging-to-test ASD pediatric population.
