My research concerns interneural integration and information processing in the neocortex of mammals. We are observing neuronal activity in the neocortex using a combination of various techniques, including the intrinsic optical signal (a drop in light reflectance that correlates with an increase in electrophysiological activity), and voltage sensitive dyes. At the central of our project is a problem of spatiotemporal representation of the information in the brain.
