Space representation in unilateral spatial neglect.

Space representation in unilateral spatial neglect.

Patients with unilateral brain lesions were given a task requiring exploration of space with the hand in order to assess the visual dependency of unilateral spatial neglect. The task was carried out both without visual control and under visual control. Performances were compared with that of normal subjects. Results were :(1) patients with right brain damage with no visual field defect demonstr...

Swan Unilateral Spatial Neglect

Combining language and space: sentence bisection in unilateral spatial neglect.

In line bisection right-brain-damaged patients with left spatial neglect show a rightward deviation, with respect to the line's physical center. In word bisection ortho-phonological features of the stimulus' final (right-sided) part modulate performance of both patients and healthy participants (Veronelli, Vallar, Marinelli, Primativo, & Arduino, 2014). We investigated the role of linguistic fa...

Unilateral Neglect and the Structure of Space Representation

Lesions of particular districts of one side of the brain—most often, and for reasons that are still unclear, the right side—entail neglect of the opposite (contralesional) side of egocentric space. Patients usually behave as if the neglected side did not exist, indeed, as if it had never existed. They neglect not only what is contingently located on the contralesional side of external objects o...

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...
