Effectiveness of Training for 54 Patients with Left Unilateral Spatial Neglect

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...

Leftward search in left unilateral spatial neglect.

The authors' previous study with an eye camera revealed that when asked to mark the centre of a line patients with left unilateral spatial neglect persist in fixating a point on its right part and place the subjective midpoint there without searching leftwards. The present study examined the patterns of leftward search of nine patients with left unilateral spatial neglect when they were require...

Swan Unilateral Spatial Neglect

Auditory midline and spatial discrimination in patients with unilateral neglect.

Patients with unilateral neglect frequently show a bias in their subjective midline, as measured by pointing, or by a purely perceptual visual task (Ferber and Karnath, 1999). The subjective straight ahead has also been measured in audition. Vallar et al. (1995), Kerkhoff et al. (1999) and Tanaka et al. (1999) have all described a shift of the auditory midline to the right. We consider several ...

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...
