There has been an explosion of knowledge over the past 15 years about how different areas of the human brain contribute to our visual experience of the world. These advances have come from a convergence of several different methodologies: brain imaging, studies of patients with specific kinds of brain damage, and physiological studies of animals. A.D. Milner and M.A. Goodale have summarized these developments in a recent book (Sight Unseen , Oxford University Press, 2003). The present application is directed at combining two of these investigative methods, by not only studying the behaviour and perceptual abilities of certain patients with specific brain damage, but also studying which parts of their brains are active during such tests by means of functional neuroimaging (fMRI). This should help us understand better the functions of the two visual streams, as well as how the brain can adjust to severe damage to one of the two streams.

在过去的15年里，关于人类大脑的不同区域如何影响我们对世界的视觉体验的知识出现了爆炸式的增长。这些进步来自几种不同方法的融合：脑成像，对特定类型脑损伤患者的研究，以及对动物的生理研究。M.A. Milner和M.A. Goodale在最近的一本书中总结了这些发展（Sight Unseen，牛津大学出版社，2003）。目前的应用旨在结合这两种调查方法，不仅通过研究某些特定脑损伤患者的行为和感知能力，而且还通过功能神经成像（fMRI）研究他们大脑的哪些部分在这些测试中是活跃的。这将有助于我们更好地理解这两种视觉流的功能，以及大脑如何适应其中一种视觉流的严重损伤。
