Research Description

Our research investigates the principles of brain organization that underlie executive control, reasoning and decision making. Through a combination of human behavioral, computational modeling, functional neuroimaging (fMRI) and neuropsychological patient data, we seek to uncover the mechanisms that shape higher cognitive processes and to develop predictive models of brain function that link neural systems to specific patterns of inference and behavior. An important motivation for our work is the development of a theoretically sound foundation for research on the relationship between disturbances of brain function and their manifestation as disorders of thought and behavior in psychiatric illness and neurological disease. Dr. Barbey's research group is supported by the White House BRAIN Initiative, the research division of the United States Director of National Intelligence (IARPA), the National Institutes of Health, the National Science Foundation, and Abbott Nutrition.

Building Remodeling Projects

Click on the title to check out these pictures from the classroom remodeling project in the basement. A second project to replace the elevators will begin in September. Beginning with the freight elevator, each elevator will be out of service for three months. To get quickly from one floor to another, and improve your fitness, we will encourage the use of the stairs. The repainting of the northeast stairwell has been completed, and the painter is starting on the southwest stairwell. The repainted stairwell looks astonishingly better. Be sure to thank Rick, the painter, who has been working hard on the repainting for many weeks.
