Hemianopic visual field defects elicit hemianopic scanning
Previous explanations for the variability in success of compensating for homonymous hemianopia (HH) has been in terms of extent of the brain injury. In using on-line eye movement registrations, we simulated HH in 16 healthy subjects and compared their scanning performance on a dot counting task to their own "normal" condition and to real HH patients' performance. We evidenced clear parallels be...
متن کاملComplex visual hallucinations in the hemianopic field.
From 120 patients with an homonymous hemianopia 16 experienced complex visual hallucinations in the hemianopic field. The brain lesion was located in the occipital lobe, though damage was not limited to this area. Complex hallucinations appeared after a latent period. They were weak in colour and stereotypical in appearance, which allowed differentiation from visual hallucinations of other caus...
متن کاملInfluence of Hemianopic Visual Field Loss on Visual Motor Control

Patients with HH often misperceive visual space. Here we investigated how HH affects visual motor control. METHODS AND FINDINGS Seven patients with complete HH and no neglect or cognitive decline and seven gender- and age-matched controls view...
