Perception and Action in 'Visual Form Agnosia'.
Brain, 1991 A single case study of a patient with 'visual form agnosia' is presented. A severe visual recognition deficit was accompanied by impairments in discriminating shape, reflectance, and orientation, although visual acuity and colour vision, along with ...

, 2010 The visual system has the function of visual perception, ie the analysis of form, movement and color of objects presented in the visual field. The processes that allow this analysis lies primarily in the visual cortex, and in particular in the primary ...

Evidence for Perceptual Deficits in Associative Visual (Prosop)Agnosia: A Single-Case Study
Neuropsychologia, 2004 Associative visual agnosia is classically defined as normal visual perception stripped of its meaning [Archiv für Psychiatrie und Nervenkrankheiten 21 (1890) 22/English translation: Cognitive Neuropsychol.

Visual agnosia is defined as an impairment of object recognition, in the absence of visual acuity or cognitive dysfunction that would explain this impairment. This condition is caused by lesions in the visual association cortex, sparing primary visual cortex.

Following an acute hypotensive episode, a patient had unusual residual visual difficulties. A right homonymous hemianopsia was the only primary neurologic deficit, but there were specific behavioral disturbances. He could not read but could write (alexia without agraphia), had difficulty in color recognition (color agnosia), facial recognition ...

Abstract 1. (1) Visual perception is no passive process but a very active one, which entails visual search, looking, selection and rejection, choice of critical details, elaboration, synthesis, and articulation based on past experience and mnestic processes. 2.

Brain, 1999 We report the effects of the passage of time on the long-term visual knowledge for objects in a patient with visual agnosia (H.J.A.). The naming of real objects was found to have improved, although this was not associated with any change in H.J.A.’s ...

The anatomic basis of visual agnosia
Neurology, 1979In a patient with associative visual agnosia without alexia, there was bilateral infarction in the distribution of the posterior cerebral arteries, with corticosubcortical lesions in both occipitotemporal regions, sparing the corpus callosum. Bilateral loss of visual-limbic connections may underlie associative visual agnosia, and bilateral lesions of ...

Occlusive vascular disease of the posterior cerebral arteries produced infarction destroying the left medial occipital area, the splenium of the corpus callosum, and the right inferior longitudinal fasciculus of a patient with visual agnosia. Some of the reported neurobehavioral abnormalities (alexia without agraphia, color agnosia, and verbal memory ...

A 41-year-old man presented with bilateral posterior cerebral artery infarcts. He had visual object agnosia and prosopagnosia with preservation of reading abilities. There was also defective visual memory, topographic orientation, and color perception, as well as simultanagnosia. From the clinical facts and CT findings, it was postulated that bilateral
