visual extinction

a form of visual neglect in which a previously visible stimulus in one half of the visual field is not consciously reported when a second stimulus appears simultaneously in the other half of the visual field. Visual extinction occurs as a result of brain damage, usually to the parieto-occipital cortex contralateral to the visual field in which the extinction occurs.
