A Spatial Working Memory Component to Visuospatial Neglect

In the hemispatial neglect syndrome, usually due to a right inferior parietal lesion, patients tend to only search the ipsilateral half of the visual scene. Several lines of research suggest that multiple components underlie the neglect syndrome but a common theme has been a bias of attention. In an experimental paradigm using a visual search task a single case study indicated impaired spatial working memory (SWM) across saccades contributing to abnormal search in neglect.
