We tested in great detail face perception and face memory in four cases of prosopagnosia. Three of them showed deficits of face perception and/or of familiar faces memory. There was one prosopagnosic patient, however, who showed no abnormality in face perception and discrimination and could recall familiar faces. This case suggests that a form of prosopagnosia may exist, which is due to the disconnection between face perception and face memory. X-ray CT, MRI and PET studies revealed that two patients did not have damage of the left hemisphere, supporting the view that prosopagnosia can arise from unilateral right-sided lesion.
我们对4例面孔失认症患者的面孔感知和面孔记忆进行了详细测试。其中3例表现出面孔感知和/或熟悉面孔记忆缺陷。然而，有1例面孔失认症患者在面孔感知和辨别方面没有异常，并且能够回忆起熟悉的面孔。该病例表明可能存在一种面孔失认症形式，其是由于面孔感知和面孔记忆之间的联系中断所致。X射线CT、MRI和PET研究显示，2例患者左半球没有损伤，这支持了面孔失认症可由右侧单侧病变引起的观点。
