The orderly layout of visual fibres in the optic nerves of cichlid fishes suggests that they are guided most of the way to the brain by contact with their neighbours. Before they reach the visual map in the tectum, however, their arrangement in the cross-section of the nerve is reorganised in a way which requires longer-range guidance.
丽鱼科鱼类视神经中视觉纤维的有序排列表明，它们在通往大脑的大部分路程中是通过与相邻纤维接触来引导的。然而，在它们到达中脑顶盖的视觉图谱之前，它们在神经横截面上的排列会以一种需要更远距离引导的方式重新组织。
