Visual information processing in hemispatial neglect.
Hemispatial neglect is a complex neuropsychological disorder characterized by a severe attentional deficit that produces a lack of awareness for information appearing in contralesional hemispace. Despite this lack of phenomenal awareness, recent studies suggest that a great deal of visual information processing does occur and can influence the performance of patients in certain tasks. The curre...
متن کاملImpaired orientation processing in hemispatial neglect.
Patients with hemispatial neglect show deficits in size perception. We investigated how this effect would be modulated by a change in object orientation. Seven right-hemisphere-lesioned patients, with and without neglect, and a control group, were asked to indicate which one of two bilaterally presented lines was longer, shorter or the same. Depending on the participant's response, the length w...
متن کاملHemispatial 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 کاملNeural plasticity and hemispatial neglect in stroke.
The ability to outline the world and our place in it characterises our humanity. Stroke or brain injury can alter this world-making capability temporarily or permanently. The stroke patient's world, once intelligible and practicable, is transformed into a confusing, unapproachable and hostile environment. The skills of intellect, sensation, awareness and movement, which are honed over the cours...
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...
