N2 - ABSTRACTIt has been suggested that word- and face recognition rely on a common cerebral network for perceptual processing. To further explore this hypothesis, face- and word recognition were assessed in seven patients with focal lesions after stroke of the posterior cerebral artery in either hemisphere. The aim was to investigate if problems in face- and word recognition would co-occur, if testing was sensitive and patients were not pre-selected based on behavioural symptoms. Patients and matched controls were given a reading test and a delayed matching paradigm with faces, objects, and words. Interestingly, all patients with word recognition difficulties had problems in face recognition, independently of the affected hemisphere, supporting the existence of a bilateral perceptual network for faces and words. However, two patients showed selective face recognition problems after unilateral damage to either hemisphere, suggesting that parts of this network may be more critical for face than for word recognition.
