It's rabbit retina, cells look perhaps a bit different in mouse retina.
First thought green looks like horizontal cell in mouse retina:
but certainly author is correct
Cell bodies of bipolars are out of dataset in our set, and we only see the dendrites. @annkri , and i think dendrites in our set are just expanding less laterally then in rabbit-eye (only one cell).
After studying a bit the original paper, i would say:
green: dendritic field of off-cone bipolar cell (Ba1) in rabbit-eye. Cell contacts with red and blue
red: cone pedicles
blue: rod spherules
