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 کاملLeft size distortion (hyperschematia) after right brain damage.
OBJECTIVE To quantitate a size distortion involving the side of space contralateral to the lesion (contralesional) in two right-brain-damaged patients. METHODS We studied two right-brain-damaged patients with lesions sparing the occipital lobe and a mild left neglect on target cancellation or line bisection. The lesions involved the temporoparietal region (Patient 1) and the basal ganglia and...
متن کاملRight 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...
متن کاملIpsilateral neglect for non-verbal stimuli following left brain damage.
Unilateral spatial neglect (USN) is usually defined as the failure of unilateral brain damaged patients to attend or respond to stimuli in the hemispace contralateral to the site of lesion. This definition encompasses either a complete lateralisation of omissions or their asymmetric distribution in space, whereby only a few are committed ipsilaterally (Gainotti et al., 1990). A few exceptions t...
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")...
