As shown by autoradiographic techniques, the pattern of retinogeniculate projections in the pigmented rabbit is generally similar to that described in previous studies. Each retina projects bilaterally to the alpha segment of the dorsal lateral geniculate nucleus (LGd) and to the external segment of the ventral lateral geniculate nucleus (LGv). The beta segment of the LGd and internal layer of the LGv receive contralateral inputs only. The alpha segment of the LGd contains an irregularly shaped region which receives overlapping bilateral projections. Within this region the ipsilateral input is continuous and predominant. This pattern of ipsilateral projection can account for both the laminar arrangement perpendicular to the lines of projection and the "hidden lamination" which have been described previously for the rabbit LGd. A separate bilateral projection is identified for a group of cells lying between the LGd and LGv rostrally. Caudally this intergeniculate leaflet extends medial and ventral to the LGv and appears to merge with the zona incerta.
放射自显影技术显示，有色家兔视网膜至外侧膝状体的投射模式与先前研究中所描述的大体相似。每只视网膜双侧投射至背侧外侧膝状体核（LGd）的α段和腹侧外侧膝状体核（LGv）的外侧段。LGd的β段和LGv的内层仅接受对侧输入。LGd的α段包含一个不规则形状的区域，该区域接受重叠的双侧投射。在该区域内，同侧输入是连续且占主导的。这种同侧投射模式可以解释先前针对家兔LGd所描述的垂直于投射线的分层排列和“隐藏分层”。在LGd和LGv之间靠前的一组细胞存在单独的双侧投射。在尾侧，这个膝间小叶向内侧和腹侧延伸至LGv，并似乎与未定带融合。
