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… 
Case of right hemispatial neglect and transcortical sensory aphasia following left occipitotemporoparietal glioblastoma resection
TLDR
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.
Neglect and Balint’s Syndrome
Reliability and validity of the Virtual Reality Lateralized Attention Test in assessing hemispatial neglect in right-hemisphere stroke.
TLDR
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.
Hemispatial neglect and deficits of verticality perception after stroke - neuropsychological results and modulation via galvanic vestibular stimulation
TLDR
Both GVS and tDCS over the parietal cortex were proven to be able to modulate neglect and related disorders, with little evidence showing GVS-induced modulation of deficits of verticality perception.

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 cognitive

Extrapersonal Visual Unilateral Spatial Neglect and Its Neuroanatomy
TLDR
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.
Neurophysiological and neuropsychological aspects of spatial neglect.
Mechanisms of unilateral spatial neglect in relation to laterality of cerebral lesions.
TLDR
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.
Anatomy of Spatial Attention: Insights from Perfusion Imaging and Hemispatial Neglect in Acute Stroke
TLDR
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.
Do We Need the “Lateral” in Unilateral Neglect? Spatially Nonselective Attention Deficits in Unilateral Neglect and Their Implications for Rehabilitation
TLDR
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.
Neural Circuits for Spatial Attention and Unilateral Neglect
Systematic analysis of deficits in visual attention.
TLDR
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.
Motor Minds and Mental Models in Neglect
TLDR
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.
Motor role of human inferior parietal lobe revealed in unilateral neglect patients
TLDR
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.
