BACKGROUND Spatial working memory dysfunction has been suggested to be a cardinal feature of schizophrenia. But schizophrenia is heterogeneous in its clinical profile, course, and outcome. One fundamental contributor to this heterogeneity may be gender. No report has yet addressed gender differences in spatial working memory, as measured by the delayed-response task (DRT). METHODS We aggregat...

In earlier work, patients with hippocampal damage successfully path integrated, apparently by maintaining spatial information in working memory. In contrast, rats with hippocampal damage were unable to path integrate, even when the paths were simple and working memory might have been expected to support performance. We considered possible ways to understand these findings. We tested rats with e...
