What can happen if the connection between the brain and the visual system is disrupted or damaged? What can cause patients to act as if part of their world not only doesn't exist, but couldn't exist? In this lecture, we will discuss blindsight and neglect and see how studies on these patients have provided insights on how our brains receive and interpret information about the world.
Keywords: blindsight, neglect, attention, extinction, visuospatial agnosia, hemispatial neglect, anosagnosia, right and left inattentive, parietal cortex, temporal cortex, representational theory, M. Posner.
