| Outline of Final Research Achievements |
We successfully applied organotypic adult retina culture system with gene-gun to marmoset retina. Especially, we introduced GFP plasmid into marmoset retinal ganglion cells, and found a morphological diversity of retinal ganglion cells beside well-known midget and parasol ganglion cells. In addition, we introduced PSD95-GFP, synaptic maker, plasmid into retinal ganglion cells and analyzed dendritic localization pattern of synapses in different subtypes of retinal ganglion cells. By this method, we found narrow thorny retinal ganglion cells almost exclusively receive synaptic inputs from DB6 bipolar cells, and project into K1 layer of lateral geniculate nucleus.
