Through the Eyes of Neglect Patients: A Preliminary Eye-Tracking Study of Unilateral Spatial Neglect

Through the Eyes of Neglect Patients: A Preliminary Eye-Tracking Study of Unilateral Spatial Neglect.

To the Editor: The incidence of unilateral spatial neglect (USN) has been described in up to 30%270% after an injury to the right hemisphere. USN is one of the strongest predictors of poor functional recovery, which can lead to more prolonged hospitalization and disrupt rehabilitation and recovery of functional disabilities after stroke, thus limiting independence. However, USN is not usually a...

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...

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...

Right unilateral spatial neglect of the left brain-damaged patients.

Right unilateral spatial neglect (USN) was investigated on three left brain-damaged patients suffering from the right homonymous hemianopsia and hemiplegia. A test battery consisted of visuo-constructive praxis; 1) putting blocks into a box, 2) bisecting a horizontal line, 3) figure drawing, 4) drawing of a dial plate and 5) copying drawing. The investigation revealed that USN of left brain-dam...
