Signs of spatial neglect in unilateral peripheral vestibulopathy

European Journal of Neurology, 2021
AbstractBackground and purposeIn this study, the question of whether egocentric representation of space is impaired in chronic unilateral vestibulopathies was examined. The objective was to test current theories attributing a predominant role to vestibular afferents in spatial cognition and to assess whether representational neglect signs are common in

Eye movements and verbal report in a single case of visual neglect [PDF]

, 2012
In this single case study, visuospatial neglect patient P1 demonstrated a dissociation between an intact ability to make appropriate reflexive eye movements to targets in the neglected field with latencies of

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Group study of an 'undercover' test for visuospatial neglect: Invisible cancellation can reveal more neglect than standard cancellation [PDF]

, 2004
Visual neglect is a relatively common deficit after brain damage, particularly strokes. Cancellation tests provide standard clinical measures of neglect severity and deficits in daily life.

Biomimetic Hybrid‐Membrane Nanoreactor for Deep‐Seated Photodynamic Immunotherapy of Hepatocellular Carcinoma via Dual Catalysis‐Enhanced ROS Amplification and cGAS‐STING Activation

Advanced Functional Materials, EarlyView.
UCNP@MnOx‐Hyp@HRM (UMHM) enables tumor targeting and accumulation. Under 808 nm NIR irradiation, PDT/CDT synergistically triggers ICD and cGAS–STING immunity for deep hepatocellular carcinoma therapy. ABSTRACT Photodynamic therapy (PDT) is promising against hepatocellular carcinoma (HCC).

Human iPSC‐Derived Tissue‐Engineered Nigrostriatal Pathway for Chronic Restoration of Dopaminergic Axon Tracts in a Rat Parkinson's Model

Advanced Healthcare Materials, EarlyView.
Inspired by conventional cell therapy and emerging bioengineering approaches, the tissue‐engineered nigrostriatal pathway (TE‐NSP) has an anatomically‐inspired design comprising a population of human dopaminergic neurons with unidirectional, long‐projecting axon tracts.

Time and neglect: Abnormal temporal dynamics in unilateral spatial neglect

Neuropsychologia, 2006
Temporality enters our immediate experience as passage and becoming: the role time plays in the construction of a world of enduring entities tends to go unnoticed. This paper examines the relation between time and ontology in the context of unilateral neglect, a neuropsychological syndrome in which patients fail to perceive or respond to stimuli in the

Towards a Dynamic Assessment of Unilateral Spatial Neglect [PDF]

The Open Psychology Journal, 2017
Background:The traditional paper and pencil tests are often inadequate to detect the mild forms of Unilateral Spatial Neglect (USN).Objective:To verify the effectiveness of a touchscreen-based cancellation test in assessing individuals with USN.Methods:Seven individuals, six with right and one with left brain damage, who showed moderate to severe USN ...

Prehension and perception of size in left visual neglect [PDF]

, 2001
Right hemisphere damaged patients with and without left visual neglect, and age-matched controls had objects of various sizes presented within left or right body hemispace. Subjects were asked to estimate the objects' sizes or to reach out and grasp them,
