Spatial working memory deficit in unilateral neglect.
Based on the similarity of brain areas lesioned in neglect and those activated by spatial working memory (WM) tasks in normals, we hypothesized that neglect may involve spatial WM impairments. A left neglect patient with right inferior frontal and basal ganglia damage performed cancellation tasks, making either highly visible marks (to provide a reminder of visited items), or invisible marks (s...
متن کاملSpatial working memory capacity in unilateral neglect.
It has been proposed recently that a deficit in keeping track of spatial locations may contribute to the severity of unilateral neglect in some right hemisphere stroke patients. However, performance on traditional spatial working memory (SWM) tasks (e.g. Corsi blocks) might be confounded by failure to encode leftward locations, rather than a true deficit of maintaining locations in SWM. Here we...
متن کاملIs the dissociability of working memory systems for name identity, visual-object identity, and spatial location maintained in old age?
The dissociability of working memory for name identity (verbal information), visual objects, and spatial location was explored in 3 experiments. Consistent with previous results, the 3 working memory systems were dissociable in younger adults. Both younger and older adults showed involvement of name identity in an object identity task, and older adults showed this involvement in a spatial memor...
متن کاملEffects of forced exercise on object location memory and anxiety behaviour in morphine dependent ovariectomized rats
Introduction: Previous findings from our laboratory indicated that exercise alleviates the deficits in cognitive and anxiety disorders in healthy female rats. But the effect of exercise on cognitive and anxiety disorders induced by chronic morphine in experimental monopose of rats (ovariectomized) not known. Aim of this study was to investigate the effects of mild and modorate forced exercise o...
متن کاملSpatial versus Object Working Memory: PET Investigations.
We used positron emission tomography (PET) to answer the following question: Is working memory a unitary storage system, or does it instead include different storage buffers for different kinds of information? In Experiment 1, PET measures were taken while subjects engaged in either a spatial-memory task (retain the position of three dots for 3 sec) or an object-memory task (retain the identity...
