Abstract
A right-handed patient with a complete right homonymous hemianopia could not name objects seen in her left hemifield but could always select an object from an assortment when the object was named. If the right hemisphere was devoid of auditory language function, we must postulate separate transcallosal pathways from visual to verbal and from auditory language to visual information. Because only the former pathway was interrupted, our patient exhibited a "unidirectional" disconnection.
摘要
一位患有完全性右侧同向偏盲的右利手患者无法说出其左半视野中看到的物体，但当物体被说出时，她总能从一组物品中挑选出该物体。如果右半球缺乏听觉语言功能，我们必须假定从视觉到语言以及从听觉语言到视觉信息存在单独的胼胝体通路。由于只有前一条通路被中断，我们的患者表现出“单向性”分离。
