title: Subcortical neglect.
abstract: The unilateral neglect syndrome is defined as a lack of directed attention to one half of the space or the body. It has been reported mainly after cortical lesions of the right parietal or frontal lobe in man. However, there is strong experimental and clinical evidence for the existence of neglect syndromes of subcortical origin. The unilateral neglect syndrome is not the result of elementary sensory deficits. The failure in directed attention is dependent on an imbalance of hemispheric activation.
