Hemispatial neglect.
The syndrome of hemispatial neglect is characterised by reduced awareness of stimuli on one side of space, even though there may be no sensory loss. Although it is extremely common, it has proven to be a challenging condition to understand, and to treat. New insights from detailed behavioural and anatomical studies in patients, as well as functional imaging in healthy individuals, have begun to...
متن کاملCognitive neuroscience of hemispatial neglect.
INTRODUCTION Patients with neglect often fail to be aware of stimuli located on their contralesional side--the side of space opposite their brain damage. Some patients show impairments in extrapersonal space; others within personal (body) space; and some in both. Although the neglect syndrome may be associated with a distorted perception of extrapersonal or personal space, recent investigations...
متن کاملMotor Aspects of Hemispatial Neglect
A relatively common outcome of unilateral brain damage in humans is the syndrome of hemispatial neglect. Hemispatial neglect can occur following damage to a variety of brain regions but is chiefly associated with damage to the inferior parietal lobule, most frequently involving the occipito-temporo-parietal junction of the right hemisphere [1]. Neglect patients fail to respond appropriately to ...
متن کاملVisual hemispatial neglect, re-assessed.
Increased computer use in clinical settings offers an opportunity to develop new neuropsychological tests that exploit the control computers have over stimulus dimensions and timing. However, before adopting new tools, empirical validation is necessary. In the current study, our aims were twofold: to describe a computerized adaptive procedure with broad potential for neuropsychological investig...
متن کاملWhen Connectedness Increases Hemispatial Neglect
Patients with left neglect were tested with "chimeric" figures composed of the right and left halves of two different objects. The connectivity relation was modulated between the two half figures. For some displays, the two chimeric halves were separated by a small gap, while in others, the separate halves were connected by a line segment. In line with previous reports, performance on reporting...
