Injections of rhodamine-B into the dorsal raphe nucleus (DRN) and Fluoro-Gold into the lateral geniculate nucleus (LGN) revealed double-labeled retinal ganglion cells (DL RGCs) projecting to both nuclei. The soma-size distribution of DL RGCs was compared with three other distributions: DRN-projecting RGCs, LGN-projecting RGCs, and a large sample of RGCs labeled via the optic nerve with DiI. DL RGC soma diameters fell primarily within the mid-to-upper size range of all three distributions. DL RGCs may provide information to both nuclei concerning comparable aspects of light and visual stimulation via collateralized axons.
将若丹明 - B注射到中缝背核（DRN），并将荧光金注射到外侧膝状体核（LGN），结果显示双标记的视网膜神经节细胞（DL RGCs）投射到这两个核。将DL RGCs的胞体大小分布与其他三种分布进行了比较：投射到DRN的RGCs、投射到LGN的RGCs，以及通过视神经用DiI标记的大量RGCs样本。DL RGCs的胞体直径主要落在所有三种分布的中到较大尺寸范围内。DL RGCs可能通过侧支轴突向这两个核提供有关光和视觉刺激可比方面的信息。
