Research activities

The main research interest of our group is to analyse cognitive processes that enable humans to build a coherent representation of space and to select the most relevant among several stimuli. We are studying the functional characteristics and neuroanatomy of neuropsychological disorders such as spatial neglect, extinction, optic ataxia and visual agnosia as well as electrophysiological mechanisms of attention and eye movement programming in healthy subjects. The techniques used to study these phenomena involve measures of reaction time, eye movements, 3D-motion analysis, and ERPs.
