In the last 20 years, several important developments have markedly expanded our understanding of the hemispatial neglect syndrome and, more broadly, of the brain's representation of objects, space, and action. This review follows seven “threads” of scientific development to evaluate some of the changes in our thinking about the mechanisms of neglect, its key characteristics, the spatial frames of reference affected, the psychophysical properties of neglect phenomena, the relationship of neglect… Expand
Case of right hemispatial neglect and transcortical sensory aphasia following left occipitotemporoparietal glioblastoma resection
An inpatient neuropsychological evaluation with a 67-year-old, African American man presenting with right hemispatial neglect following resection of a large glioblastoma in the left occipitotemporoparietal region revealed nearly global deficits in complex visuoperception, posterior/receptive language, memory, and complex attention/executive functioning abilities, while basic attention remained intact.

Hemispatial Neglect, Balint's Syndrome and Attention
Hemispatial neglect is typically caused by a brain lesion to the right cerebral cortex. Patients with neglect have difficulty paying attention to contralesional space. It is often not total and canExpand
Disorders of Higher Cortical Function
A brief overview of the most important cognitive alterations as a consequence of focal brain damage is presented. The discipline that studies the relationship between brain damage and higherExpand
Neglect and Balint’s Syndrome
Neglect is a disabling brain disorder, typically caused by a brain lesion. Sufferers pathologically ignore contralesional stimuli. It can be egocentric or allocentric, occurs most commonly in theExpand
Reliability and validity of the Virtual Reality Lateralized Attention Test in assessing hemispatial neglect in right-hemisphere stroke.
The Virtual Reality Lateralized Attention Test is a sensitive, valid, and reliable measure of hemispatial neglect that requires no specialized equipment, is easy to administer, and is useful for both clinical and research purposes. Expand
Hemispatial neglect and deficits of verticality perception after stroke - neuropsychological results and modulation via galvanic vestibular stimulation
General Abstract III General Abstract Hemispatial neglect is a multimodal syndrome that often follows unilateral right-brain damage. Patients with hemispatial neglect fail to notice or respond toExpand
Some surprising findings on the involvement of the parietal lobe in human memory
Findings from humans and monkeys that illuminate an untraditional function of this region: memory are reviewed and various theories about the mechanistic role of the posterior parietal lobe in memory are evaluated. Expand
Cognitive Neuropsychology twenty years on
Cognitive neuropsychology began in the second half of the nineteenth century when neurologists such as Lichtheim, Wernicke, Bastian, and others began to make inferences about the cognitiveExpand
“Where is the sun” for hemi-neglect patients?
It is concluded that some disabilities presented by patients with spatial neglect may be due to difficulties processing information that is not present in the visual field or imagined in the representational scene. Expand

Extrapersonal Visual Unilateral Spatial Neglect and Its Neuroanatomy

The emerging pattern is that USN is a multifarious disorder, in which specific deficits are associated with damage localized in discrete brain regions and neural circuits, and concur with evidence from other domains to suggest a highly multicomponential neural and functional architecture of spatial cognition. Expand
Mechanisms of unilateral spatial neglect in relation to laterality of cerebral lesions.
The investigation was designed to test the hypothesis that the extent of space to be explored may have a different influence on unilateral spatial neglect of right and left brain-damaged patients, and found that inability to extract visual information from one side of the stimuli during single eye fixations may be the most characteristic feature of unilateral spatial neglected. Expand
Neurophysiological and neuropsychological aspects of spatial neglect.
Spatial Neglect is one of the few areas in Neuropsychology where clinicians, psychologists and animal experimenters have succeeded in adopting a common language. The result of interaction betweenExpand
Anatomy of Spatial Attention: Insights from Perfusion Imaging and Hemispatial Neglect in Acute Stroke
The data show that neglect can be caused by hypoperfused dysfunctional tissue not detectable by structural magnetic resonance imaging, and different forms of neglect were associated with different sites of cortical hypoperFusion. Expand
Do We Need the “Lateral” in Unilateral Neglect? Spatially Nonselective Attention Deficits in Unilateral Neglect and Their Implications for Rehabilitation
Evidence from visual and auditory attention studies is reviewed to show that unilateral neglect is very strongly associated with a fundamental loss of attentional capacity that is not confined to one region of space and that the spatial imbalance in neglect can be reduced by manipulations of the nonlateralized attentionalcapacity. Expand
Neural Circuits for Spatial Attention and Unilateral Neglect
What is the relationship between attention and unilateral neglect? In this article we review three theories that have been advanced to explain this neurological syndrome, discuss their limitations,Expand
Categorisation of ‘perceptual’ and ‘premotor’ neglect patients across different tasks: is there strong evidence for a dichotomy?
It seemed that despite the fact that all tasks essentially required a line bisection response, the perceptual and motor differences between the tasks were still great enough to result in inconsistent classifications. Expand
Systematic analysis of deficits in visual attention.
The authors develop systematic methods for analyzing such impairments in terms of Bundesen's (1990) Theory of Visual Attention and apply these in a group of 9 patients with parietal lobe lesions and variable spatial neglect, showing how differentiation of attentional impairments can be informed by a theory of normal function. Expand
Motor Minds and Mental Models in Neglect
The goal is not to explain neglect as much as to use neglect to explain the dynamics of spatial systems, and this approach assumes that coherent principles can be discovered within the heterogeneity of neglect. Expand
Motor role of human inferior parietal lobe revealed in unilateral neglect patients
It is shown that patients with right IPL lesions also have a specific difficulty in initiating leftward movements towards visual targets on the left side of space, suggesting that the human IPL operates as a sensorimotor interface, rather than subserving only perceptual functions. Expand
