Welcome to the Vision, Imaging Science and Technology Activities ( VISTA ) Lab home page. Principal Investigator: Brian A. Wandell. We use neuroimaging methods (fMRI, DTI) and behavior to study the human visual system. We are presently studying the visual pathways that contribute to reading development as well as making measurements of reorganization following injury or disease. Our work includes extensive software development of tools and simulations, and we collaborate extensively with groups in Neuroscience, Electrical Engineering, and Computer Science.
