During the last decade it has become clear that colour vision in platyrrhines (New World monkeys) differs from the uniform trichromatic pattern normally found in catarrhines (Old World monkeys, apes and human). Colour vision in most platyrrhine species is polymorphic, with many dichromatic individuals. The comparison of response properties in retinal ganglion cells and lateral geniculate cells between catarrhines and playrrhines elucidates how the evolution of trichromatic colour vision influenced the post-receptoral processing. We find that spatial and temporal processing is very similar in the platyrrhine and catarrhine retina, strongly suggesting that the retinal structure and function, found in living anthropoids, was already present in their common ancestor.
在过去十年中，很明显阔鼻猴（新大陆猴）的色觉与通常在狭鼻猴（旧大陆猴、猿和人类）中发现的统一三色视觉模式不同。大多数阔鼻猴物种的色觉是多态的，有许多双色个体。比较狭鼻猴和阔鼻猴视网膜神经节细胞和外侧膝状体细胞的反应特性，阐明了三色色觉的进化如何影响感受器后的处理过程。我们发现，阔鼻猴和狭鼻猴的视网膜在空间和时间处理方面非常相似，这有力地表明，现存类人猿的视网膜结构和功能在它们的共同祖先中就已经存在。
