Seeing and imagining the “same” objects in unilateral neglect

Seeing and imagining the "same" objects in unilateral neglect.

Dissociations between perceptual and imaginal neglect are typically investigated by using very different tasks (e.g. visual target cancellation vs. place descriptions). Here we report patients' performance on imaginal and perceptual tasks which shared identical stimuli and procedure, except for the modality of stimulus presentation. In different tasks, participants either saw towns/regions on a...

Object-centered neglect in patients with unilateral neglect: effects of left-right coordinates of objects.

Abstract When patients with right-sided hemispheric lesions neglect information on the left side, with respect to what set of spatial coordinates is left defined? Two potential reference frames were examined in this study, one where left and right are defined with respect to the midline of the viewer and/or environment (viewer/env-centered) and the other where left and right are defined with re...

Time and neglect: abnormal temporal dynamics in unilateral spatial neglect.

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 contralateral hemifield, behaving as if th...

Unilateral Neglect: Assessment and Rehabilitation

Over 795,000 individuals in the U.S. suffer from strokes annually, with 610,000 accounting for first attacks. Stroke represents the fifth leading cause of death and resulting long-term disability in the United States. Unilateral neglect (UN) is a disabling characteristic of stroke, occurring from lesion damage to one hemisphere of the brain. Individuals with UN do not respond normally to object...
