Dr. Nicolas Rougier is a full-time research scientist at the French National Institute for Research in Computer Science and Control.  During the past decades he’s been working extensively on visual attention in order to understand how we visually explore a scene.  Dr. Rougier discusses his work and  visual attention and computation neuroscience in particular.  He also dives deeper into how seeing is mostly an illusion and that we do not process all visual information that passed through our eyes and we're making deliberate (consciously or not) choices on what we concentrate.
