title: Remote memory and neglect syndrome.
abstract: Three patients with right cerebral infarctions and neglect syndrome failed to recall left hemispatial remote memories, even when the imagined orientation was reversed by 180 degrees. One patient was retested 4 months later and, although improved, continued to consistently recall more right-sided items. He was tested at east and west mental orientations with his head/eyes oriented physically to each side. Recall for items imagined in left hemispace improved 26% when his head/eye orientation was physically shifted from right to left hemispace. Findings suggest that the engrams for left-sided visuospatial memories in neglect syndrome are not destroyed, but rather fail to be activated.
