RBC dendrites overlap and share rod input. a Maximum intensity projection of a confocal image stack of two adjacent RBCs labeled with spectrally separable fluorophores via AAVs (Grm6 S -tdTomato in blue and Grm6 S -YFP in green). RBC postsynaptic sites are stained for Gpr179 (red). For visual clarity, the two RBCs were digitally isolated in Amira. Scale bar represents 2 μm. Insets on the right show higher magnification views of Gpr179 clusters contacted by either (top two panels) or both (bottom panel) RBCs. Scale bar represents 1 μm. b Representative examples of dendritic and synaptic overlap of four pairs of RBCs. Shaded areas represent dendritic territories. Rods targeted by dendrites of either RBC are marked by green and blue circles; rods targeted by dendrites of both RBCs are indicated by red circles. c, d Distributions of dendritic territory overlap (c, n = 37 pairs, n = 10 mice) and synaptic overlap (d, n = 28 pairs, n = 8 mice) between neighboring RBCs
