The aim of the present single case study was to investigate oculomotor recovery in a patient with simultanagnosia due to biparietal hypoxic lesions. Applying visual exploration as well as basic oculomotor tasks in three consecutive test sessions--i.e. 8 weeks, 14 weeks, and 37 weeks after brain damage had occurred--differential recovery was observed. While visual exploration remarkably improved, an impaired disengagement of attention persisted. The improvement of exploration behaviour is interpreted within an oculomotor network theory and implications for a deficit-specific recovery from simultanagnosia are discussed.
本单病例研究的目的是调查一名因双侧顶叶缺氧性病变导致同时失认症患者的眼球运动恢复情况。在连续三个测试阶段（即脑损伤发生后的8周、14周和37周）应用视觉探索以及基本眼球运动任务，观察到了不同的恢复情况。虽然视觉探索有显著改善，但注意力脱离受损仍然存在。探索行为的改善在眼球运动网络理论中得到解释，并讨论了从同时失认症中特定缺陷恢复的意义。
