视网膜顶盖投影模式的范围从近似线性表示的视野坐标到中脑屋顶的非线性投影的视觉空间与面积放大。“视觉条纹”是放大的水平带，反映视网膜精细结构的特化，特别是神经节细胞密度。水平视觉条纹在几种脊椎动物中很常见，包括板鳃类和哺乳动物。在硬骨鱼、爬行动物和鸟类中发现了“凸形”凹和它们在中脑表面上大大扩展的突起。
硬骨鱼中脑的皮质核含有可以被双眼的光刺激激活的神经元，这表明参与双眼视觉。
Retinotectal projection patterns range from approximately linear representations of visual field coordinates onto the midbrain roof to non-linear projections of visual space with areal magnifications. “Visual streaks” are magnified horizontal bands and reflect specializations of retinal fine structure, especially ganglion cell densities. Horizontal visual streaks are common in several vertebrate classes, including elasmobranchs and mammals. “Convexiclivate” foveae and their greatly expanded projections on the midbrain surface have been found in teleosts, reptiles, and birds.
The nucleus corticalis of the teleostean midbrain contains neurons that can be activated by photic stimulation of both eyes, suggesting involvement in binocular vision.
