This case study presents evidence for two subtle types of eye movement abnormalities following surgical resection of the left posterior pulvinar in man. First, visual fixations during vertical pattern matching are on average both increased in number and prolonged in duration compared to controls, although normal fixation durations also occur. Second, unilateral deficiencies during search and scanning performance are associated with eye movements directed into the hemifield contralateral to the lesion. Although direct damage to parietal cortex and indirect damage to other visually related structures cannot be ruled out as other explanations for these deficits, these findings are consistent with recent electrophysiological and behavioral studies of the pulvinar in both human and non-human primates, and suggests a fruitful area for further investigation of pulvinar function.
本案例研究提供了证据，表明人类左后丘脑枕手术切除后出现了两种细微的眼球运动异常类型。首先，与对照组相比，垂直图案匹配过程中的视觉注视平均数量增加且持续时间延长，不过也会出现正常的注视持续时间。其次，搜索和扫描表现中的单侧缺陷与朝向病变对侧半视野的眼球运动有关。尽管不能排除顶叶皮质的直接损伤以及对其他视觉相关结构的间接损伤作为这些缺陷的其他解释，但这些发现与最近对人类和非人类灵长类动物丘脑枕的电生理和行为研究一致，并提示这是一个进一步研究丘脑枕功能的富有成果的领域。
