Brain and Cognition Division

Gabriele Gratton's interests are in cognitive neuroscience, specifically in the basic organization (spatial, temporal, and functional) of elementary cognitive processes such as those involved in sensory and working memory, attention, motor preparation, and strategy selection. Gratton has been focusing on the application of functional brain imaging methods to the study of these processes in normal adult subjects using optical, electrophysiological and hemodynamic techniques.
