Simultanagnosia

Simultanagnosia occurs with left hemisphere damage and is an inability to see more than one thing, or all aspects of an item, at a time

Example: some complain of seeing things only in a piecemeal fashion such that objects look fragmented. In fact, by surrounding the object with other objects perceptual recognition deteriorates even further.

-Abnormal eye movements -Difficulty shifting gaze and/or performing visual search tasks - ability to scan and visually explore the environment is drastically reduced This is due to a breakdown in the ability to perform serial feature-by-feature visual analysis. -Visual attention is often largely limited to the central visual field whereas the periphery is ignored -Complaints that even objects in the central visual field tend to disappear as they stare at them
 * This condition is sometimes accompanied by **

-Lesions to the frontal eye fields -Following bilateral superior occipital lobe lesions -The lesion may be localized to the superior occipital-parietal region (area 7). Hence, the patient is no longer able to maintain visual fixation and cannot adequately focus on an object or explore its parts. This disorder has also been referred to as Balints syndrome as well as optic ataxia, paralysis of gaze, and concentric narrowing of the visual field.
