Disappearance of unilateral spatial neglect following a simple instruction

Disappearance of unilateral spatial neglect following a simple instruction.

OBJECTIVES To clarify the reason why patients with left unilateral spatial neglect fail to copy the left side of a daisy like flower, not continuing to draw petals all around. METHODS A flower was simplified and a figure was made that consisted of a large central circle and small circles surrounding it. Four patients with typical left unilateral spatial neglect performed copying and arrangeme...

Swan Unilateral Spatial Neglect

Neurobiology of unilateral spatial neglect.

Hemispatial neglect is a common and disabling consequence of stroke. Earlier studies aimed to identify a single area of the brain where damage caused neglect and sought a single disrupted process that could account for the symptoms. Recent studies have shifted toward identifying component processes and representations underlying spatial attention required for various tasks and identifying areas...

Running head: A UNIFIED PERSPECTIVE OF UNILATERAL SPATIAL NEGLECT 1 A UNIFIED PERSPECTIVE OF UNILATERAL SPATIAL NEGLECT

The aim of this review is to provide a unified perspective of unilateral spatial neglect (USN). USN is a neurological disorder frequently observed following damage or diseases to the brain. It is particularly associated with strokes to specific anatomical structures within the right hemisphere. Patients with USN fail to respond to or orient towards stimuli located in the hemispace contralateral...

Dissociable coordinate frames of unilateral spatial neglect: "viewer-centered" neglect.

Detailed analyses of reading and nonlexical tasks by three patients with unilateral spatial neglect (USN) secondary to stroke indicate that the USN in each of these patients affects the left side (contralateral to brain damage) of the viewer, with respect to the viewer's head, mid-sagittal plane of the body, or line of sight. In one case, the neglect was further specified as concerning the left...
