Abstract

This report describes a case of associative visual agnosia caused by a left sided, cortico-subcortical, inferior temporo-occipital infarction. Performance on visual perceptual tests was normal, while it was defective on visual classification tasks. Visual agnosia was interpreted as a visuo-verbal disconnection plus a categorization deficit for visual meaningful common stimuli. The left occipito-temporal lesion disrupted the visual classification process and prevented access of visual information to language areas and limbic system. The absence of right hemispheric lesion accounted for the normal recognition of familiar faces and other unique individual stimuli such as familiar places, whose recognition occurs through contextual evocation.

Dissociating 'what' and 'how' in visual form agnosia: a computational investigation.

Patients with visual form agnosia exhibit a profound impairment in shape perception (what an object is) coupled with intact visuomotor functions (how to act on an object), demonstrating a dissociation between visual perception and action. How can these patients act on objects that they cannot perceive? Although two explanations of this 'what-how' dissociation have been offered, each explanation has shortcomings. A 'pathway information' account of the 'what-how' dissociation is presented in this paper. This account hypothesizes that 'where' and 'how' tasks require less information than 'what' tasks, thereby allowing 'where/how' to remain relatively spared in the face of neurological damage. Simulations with a neural network model test the predictions of the pathway information account. Following damage to an input layer common to the 'what' and 'where/how' pathways, the model performs object identification more poorly than spatial localization. Thus, the model offers a parsimonious explanation of differential 'what-how' performance in visual form agnosia. The simulation results are discussed in terms of their implications for visual form agnosia and other neuropsychological syndromes.

Object orientation agnosia: a failure to find the axis?

A dissociation between the ability to recognize misoriented objects and to determine their orientation has been reported in a small number of patients with vascular lesions. In this article, we describe a 57-year-old man with probable Alzheimer' s disease who shows the same dissociation. Neuroimaging findings indicated marked hypometabolism in the posterior cortical regions, particularly the postero-superior parietal lobes. Clinically, the patient had good object recognition accompanied by severely impaired spatial abilities. The experimental investigations comprised a variety of tasks in which he identified misoriented objects, evaluated the orientation of single objects, or discriminated the orientation of simultaneously presented items. Results revealed that his object recognition was independent of orientation and was largely mediated by salient features. With respect to orientation judgements, the patient displayed a profound inability to judge the orientation of nonupright objects, but remarkably intact (though largely implicit) knowledge of the upright orientation. Strikingly, his orientation judgements were also more accurate for upside-down objects than for other orientations (i.e., 90 degrees ). We interpret these results as evidence that judgements about object orientation are facilitated when the orientation of the principal axis of the object matches that of an internal representation. We propose that the inability to determine other orientations may be due to the failure of an "axis-finding" mechanism implemented in the posterior parietal lobes, that translates between object-centered and eye-centered coordinates appropriate for guiding visual scanning.

Agnosia for familiar faces and odors in a patient with right temporal lobe dysfunction.

The authors studied a 53-year-old man with progressive prosopagnosia and inability to recognize his favorite foods by smell. He could not identify pictures of familiar faces, but he could match unfamiliar faces and distinguish them from familiar ones. He could not identify familiar odors, but he could detect them and could perceive them as pleasant or familiar. Neuroimaging revealed temporal lobe changes, especially on the right. Right temporal lesions may produce face and odor agnosia by preventing perceptual familiarity units from accessing semantic associations.
