Emotional hyporeactivity to visual stimuli (so-called visual hypoemotionality) was observed in a 71-yr-old woman following a cerebral infarction in the territory of the posterior cerebral arteries. Other visual disturbances included severe prosopagnosia, dense left hemianopia and mild left hemineglect. There was neither object agnosia nor any involvement of language, memory or intellectual functions. Hypoemotionality was found only for visual stimuli, since auditory and tactile modalities were totally spared, suggesting a visual-limbic disconnection mechanism. From CT data, and referring to previous evidence suggesting a right-hemisphere prevalence for emotional functions, it is postulated that the right occipital lesion, leading to a total right temporal lobe isolation, was mainly responsible for the patient's emotional disturbances.
在一名71岁女性患者中，观察到其大脑后动脉供血区发生脑梗死后出现对视觉刺激的情感反应减退（即所谓的视觉情感减退）。其他视觉障碍包括严重的面孔失认症、左侧致密性偏盲和轻度左侧半侧空间忽视。既没有物体失认症，语言、记忆或智力功能也未受影响。情感减退仅见于视觉刺激，因为听觉和触觉模态完全未受影响，提示存在视觉-边缘系统分离机制。根据CT数据，并参考先前表明情感功能以右侧半球为主的证据，推测右侧枕叶病变导致右侧颞叶完全孤立，这是该患者情感障碍的主要原因。
