[Current researches on the morphology of retinal ganglion cells].

Retinal ganglion cells (RGC) is only neuron in retina which mediate information from retina and project to the brain. Markers specific to individual retinal neuronal cell types have not been forthcoming, so the most general method remains neuronal morphology which is simple and observational. The synaptic connectivity and physiology characteristic can be described. The diversity of RGS is reviewed.
