The existence of colour-generating interactions across the corpus callosum has recently been suggested from observations with a 'split-brain' patient, thus indicating long-range colour computations at the cortical level. Observations on induced colours described here suggest long-range colour computations at the retinal level. If a white surface surrounded by a particular colour is fixated for some time, the resulting after-image has two colours: the surround appears in complementary colour, whereas the white centre takes on the colour of the surround. The question of whether such colour induction is located in the retina or more centrally was tested in a brain-injured patient with hemianopia. It could be demonstrated that areas of the visual field that are no longer represented in the geniculo-striatal pathway still contribute to colour induction, suggesting that colour induction is a retinal phenomenon.
最近，通过对一名“裂脑”患者的观察表明，胼胝体存在产生颜色的相互作用，这表明在皮层水平存在远距离颜色计算。此处描述的关于诱导颜色的观察表明，在视网膜水平也存在远距离颜色计算。如果将被特定颜色包围的白色表面注视一段时间，产生的后像有两种颜色：周围呈现互补色，而白色中心呈现周围的颜色。在一名患有偏盲的脑损伤患者中，测试了这种颜色诱导是位于视网膜还是更靠中枢的问题。可以证明，在膝状体 - 纹状体通路中不再有代表的视野区域仍然对颜色诱导有贡献，这表明颜色诱导是一种视网膜现象。
