When elephants fly: differential sensitivity of right and left inferior frontal gyri to discourse and world knowledge.

abstract：:The aim of the present study was to assess the relationship between overt and covert orienting of attention in visual neglect patients with parietal and fronto-parietal lesions. Two stimuli were presented at eccentricities of 8° or 20° to the left (LVF) or right (RVF) visual fields and the patient was required to main...
