Dr. Steve Petersen, PhD, Professor of Neurology, Radiology, Anatomy & Neurobiology, Biomedical Engineering, Psychology and Neurological Surgery at Washington University. Dr. Petersen’s lab uses behavioral and functional neuroimaging techniques (fMRI) to study neural mechanisms underlying attention, language, learning and memory as well as network properties of the brain. Their goal is to characterize the development of brain systems (e.g. the default mode network) in a way that is comprehensive within a given system, as well as the relationships between systems in a wider network context. They focus on ways in which functional connectivity and network properties change across development, in aging, and in neuropsychiatric disorders. They are particularly interested in the development of neural mechanisms underlying reading, with an emphasis on how visual regions in the brain change as people become fluent readers. They work to identify and characterize fMRI and fcMRI signals related to task organization and executive control. This work has led to describing the function of two relatively independent task control networks; one working to maintain task set or goals, the other related to task initiation and adjustment of ongoing performance.
