My first research interest is about how the brain represents Visual Space, i.e., how the world is represented in the brain. Spatial perception, which is the way for constructing an internal representation of perceived space, uses both visual and motor information. The nature of this representation and the neural mechanisms underlying it, have become a topic of great interest in both psychophysics and cognitive neuroscience. From these two approaches we try to understand how the brain rebuilds such spatial representations or Visual Space. To understand the intrinsic geometry that the brain uses to represent the perceived visual space we perform experiments on the mapping between the Physical Space (objectively measured with devices) and the Visual Space (subjectively obtained by using psychophysical methods).
