Right unilateral spatial neglect of the left brain-damaged patients.
Right unilateral spatial neglect (USN) was investigated on three left brain-damaged patients suffering from the right homonymous hemianopsia and hemiplegia. A test battery consisted of visuo-constructive praxis; 1) putting blocks into a box, 2) bisecting a horizontal line, 3) figure drawing, 4) drawing of a dial plate and 5) copying drawing. The investigation revealed that USN of left brain-dam...
متن کاملLeft unilateral neglect or right hyperattention?
BACKGROUND Contradictory interpretations of left unilateral neglect suggest that it reflects either decreased attention toward the left or increased attention toward the right. According to the right-hyperattention postulate, increasing severity of neglect should result from an increasingly stronger bias toward the right. Thus, response times to right-sided targets should become progressively f...
متن کاملStructural white-matter connections mediating distinct behavioral components of spatial neglect in right brain-damaged patients.
Spatial neglect is a neuropsychological syndrome in which patients fail to perceive and orient to stimuli located in the space contralateral to the lesioned hemisphere. It is characterized by a wide heterogeneity in clinical symptoms which can be grouped into distinct behavioral components correlating with different lesion sites. Moreover, damage to white-matter (WM) fiber tracts has been sugge...
متن کاملLeftward search in left unilateral spatial neglect.
The authors' previous study with an eye camera revealed that when asked to mark the centre of a line patients with left unilateral spatial neglect persist in fixating a point on its right part and place the subjective midpoint there without searching leftwards. The present study examined the patterns of leftward search of nine patients with left unilateral spatial neglect when they were require...
متن کاملLanguage-specific Dysgraphia in Korean Patients with Right Brain Stroke: Influence of Unilateral Spatial Neglect
The purpose of the present study was to investigate the relationship between Korean language-specific dysgraphia and unilateral spatial neglect in 31 right brain stroke patients. All patients were tested for writing errors in spontaneous writing, dictation, and copying tests. The dysgraphia was classified into visuospatial omission, visuospatial destruction, syllabic tilting, stroke omission, s...
