My fields of interests are focused on 3-D visual perception and spatial localization. For several years I developed a thematic in the behaving rhesus monkey showing that the primary visual cortex is a cortical site in which a range of retinal and extraretinal signals related to eye position interact for localizing objects in 3-D space, especially in the straight ahead axis. I also investigate visual 3-D perception in human and non human primate using VEP and fMRI techniques. Collaboration with clinics aims at developing rehabilitation protocols using perceptual learning in patients affected by age-related macular degeneration (AMD).
