先前的研究表明，单侧忽视的各种症状，包括主观中线向右的病理性移动，可以通过短时间适应视野向右的棱柱状移动来改善。我们在此报告改善想象忽视后棱镜暴露在病人的左单侧忽视。尽管在心理图像和常规测试中观察到强烈的忽视，但在棱镜适应到右侧后，从法国地图的内部图像中对左侧信息的心理唤起完全恢复了。这种改善不能用棱镜适应引起的视运动反应的改变来解释。因此，棱镜适应可能不仅在感觉-运动水平上起作用，而且在心理空间表征和/或探索的更高认知水平上起作用。
Previous work has shown that various symptoms of unilateral neglect, including the pathological shift of the subjective midline to the right, may be improved by a short adaptation period to a prismatic shift of the visual field to the right. We report here the improvement of imagined neglect after prism exposure in a patient with a left unilateral neglect. Despite a strong neglect observed for mental images as well as for conventional tests, the mental evocation of left-sided information from an internal image of the map of France map was fully recovered following prism adaptation to the right. This improvement could not be explained by the alteration of visuomotor responses induced by the prism adaptation. Prism adaptation may therefore act not only on sensory-motor levels but also on a higher cognitive level of mental space representation and/or exploration.
