抄録

     The patient was a 68-year-old female who had landmark agnosia caused by a lesion of the medial occipitotemporal area.<br>     A visual perception test demonstrated preserved fundamental visual function and normal recognition for simply presented objects, but she showed simultanagnosia. She was unable to integrate elements of stimuli and to perceive their global configuration in recognizing and remembering a landscape. In order to understand large-scale topographical representations, it is necessary to recognize buildings and the layout of the landscape integrating this with partial information. The patient had severe deficits of visual integration regarding layout and context of the landscape, and as a result might appear to have landmark agnosia. The landmark agnosia and simultanagnosia that she presented are similar, and this similarity is thought to be associated with proximity of their neural bases.
