Right-sided representational neglect after left brain damage in a case without visuospatial working memory deficits.
Brain damaged patients suffering from representational neglect (RN) fail to report, orient to, or verbally describe contra-lesional elements of imagined environments or objects. So far this disorder has only been reported after right brain damage, leading to the idea that only the right hemisphere is involved in this deficit. A widely accepted account attributes RN to a lateralized impairment i...
متن کاملPreserved visuo-spatial transformations in representational neglect.
Patients with representational unilateral neglect were impaired in immediate recall of novel material on the neglected side as presented (viewed and removed or verbally described) or following mental rotation. Transforming material from the neglected (left) side to the non-neglected (right) side resulted in no additional loss; patients were unimpaired in directing attention to the neglected sid...
متن کاملLeft on the right: allochiria in a case of left visuo-spatial neglect.
A patient with left visuo-spatial neglect after right fronto-parietal haemorrhage failed to cross out stimuli in left space on cancellation tests. Her bisections of horizontal lines were displaced significantly to the right of true centre. On drawing and copying tasks, she sometimes omitted features on the left (neglect) and sometimes transposed them to right space (allochiria). This co-occurre...
متن کاملMultimodal spatial orientation deficits in left-sided visual neglect.
Patients with right-sided temporo-parietal lesions often show contralesional neglect. However, neglect patients may also show spatial-perceptual deficits beyond the bisection and space exploration deficits frequently assessed in the horizontal plane, that is, deficits in the judgment of the subjective visual vertical or horizontal. In a recent study (Kerkhoff, G. & Zoelch, C.. Disorders of visu...
متن کاملLost in number space after right brain damage: a neural signature of representational neglect.
The human brain represents numbers along a mental number line, whose spatial nature was confirmed by studies of patients with visuospatial neglect. Here we describe a neural signature of neglect for the left "number space" by using a task that does not require manipulation of numbers. Patients were asked to discriminate an infrequent ("one" or "nine") from a frequent spoken number word ("five")...
