荧光显微镜已经揭示了一种新型的含胺视网膜神经元，网间细胞，在两个网状层中延伸突起。金鱼和猕猴玻璃体内注射5，6-二羟色胺后，电镜下可观察到这些细胞的突起。在金鱼中，这些突起位于内丛状层中的无长突细胞的突触前和突触后，位于外丛状层中的双极和水平细胞的突触前。因此，网间细胞提供了从内到外网状层的视网膜内离心通路。
Fluorescence microscopy has revealed a new type of amine-containing retinal neuron, the interplexiform cell, that extends processes in both plexiform layers. After intravitreal injection of 5,6-dihydroxytryptamine in goldfish andCebusmonkey, the processes of these cells can be identified by electron microscopy. In goldfish, the processes are pre- and postsynaptic to amacrine cells in the inner plexiform layer and presynaptic to bipolar and horizontal cells in the outer plexiform layer. Interplexiform cells thus provide an intraretinal centrifugal pathway from inner to outer plexiform layers.
