Visual imagery, like vision as such, is widely thought to be supported by two distinct and dissociable processing streams, dedicated to object representation and spatial analysis respectively. However, this simple dichotomy has been contested, with recent studies suggesting that impairments in perception-for-action and visuo-spatial imagery may reflect a more general deficit in space-based attention. Although previous studies have revealed the impact of brain damage on artistic expression, few have examined the impact on artistic expression in terms of the perceptual and spatial components of either visual processing or visual imagery. Here we present the case of an artist whose artistic expression was dramatically affected following devastating posterior brain damage. Of particular interest, we demonstrate how these changes relate to impairments in integrating and aligning different spatial features in both visual processing and visual imagery, suggestive of a general simultanagnosia not previously described.

顶枕梗塞后视觉感知，图像和艺术制作中的空间处理受损。

像图像这样的视觉图像被广泛认为是由两个不同且可分离的处理流支持的，这两个处理流分别致力于对象表示和空间分析。但是，这种简单的二分法一直存在争议，最近的研究表明，对动作的感知和视觉空间图像的损害可能反映出太空注意的更普遍缺陷。尽管先前的研究已经揭示了大脑损伤对艺术表达的影响，但很少有人从视觉处理或视觉图像的感知和空间成分方面考察对艺术表达的影响。在这里，我们以一位艺术家的情况为例，该艺术家的艺术表现在毁灭性的后脑损伤后受到了极大的影响。特别感兴趣的是
