Sensitivity of clinical and behavioural tests of spatial neglect after right hemisphere stroke
TLDR
The results of this study support the assumption that neglect is a heterogeneous disorder and that behavioural assessment of neglect in daily life was more sensitive than any single paper and pencil test. Expand
A battery of tests for the quantitative assessment of unilateral neglect.
TLDR
Assessment of UN should rely on a battery of quantitative and standardised tests, including paper-and-pencil tests, an assessment of personal neglect, extinction, and anosognosia, and a behavioural assessment, the Catherine Bergego Scale (CBS). Expand
Damage to white matter pathways in subacute and chronic spatial neglect: a group study and 2 single-case studies with complete virtual "in vivo" tractography dissection.
TLDR
The hypothesis that anatomical disconnections leading to a functional breakdown of parietal-frontal networks are an important pathophysiological factor leading to chronic left spatial neglect is supported. Expand
Left unilateral neglect as a disconnection syndrome.
TLDR
A reappraisal of the contribution of disconnection factors to the pathophysiology of neglect is proposed based on a review of animal and patient studies and indicates that damage to the long-range white matter pathways connecting parietal and frontal areas within the right hemisphere may constitute a crucial antecedent of neglect. Expand
Two cognitive and neural systems for endogenous and exogenous spatial attention
TLDR
Behavioral evidence is reviewed to conclude that endogenous and exogenous spatial orienting constitute two independent attentional systems, with different behavioral effects, and partially distinct neural substrates. Expand
Modulating the attentional bias in unilateral neglect: the effects of the strategic set
TLDR
Three experiments tested the hypothesis that attentional bias in neglect involves primarily exogenous, or stimulus-based, orienting of attention, with relatively preserved endogenous, or voluntary, orientation, and suggest that endogenous orienting is relatively spared, if slowed, in unilateral neglect. Expand
Direct Evidence for a Parietal-Frontal Pathway Subserving Spatial Awareness in Humans
TLDR
These findings suggest that parietal-frontal communication is necessary for the symmetrical processing of the visual scene. Expand
Neural correlates of cognitive impairment in posterior cortical atrophy.
TLDR
The findings provide new insight into the natural history of functional changes according to disease duration and highlight the role of parietal and occipital cortices in the cognitive syndromes that characterize the posterior cortical atrophy. Expand
Brain networks of spatial awareness: evidence from diffusion tensor imaging tractography
TLDR
It is suggested that superficial damage to the inferior parietal cortex per se may not be sufficient to produce visual neglect, and in some cases, a lesion to the direct connections between ventral occipital and frontal regions (ie, IFOF) may contribute to the manifestation of neglect by impairing the top down modulation of visual areas from the frontal cortex. Expand
The Relationship Between Visual Perception and Visual Mental Imagery: A Reappraisal of the Neuropsychological Evidence
TLDR
Artistic evidence suggests that occipital damage is neither necessary nor sufficient to produce imagery deficits, and that visual mental imagery abilities might require the integrity of brain areas related to vision, but at a higher level of integration than previously proposed. Expand
