Fig. 3

a Mixing of input (red) and output (blue) synapses on VG3 arbor. Top down view is shown above the side view. b Distribution of bipolar cell (green) and amacrine cell (magenta) inputs on VG3 arbor. c Distribution of synapses from amacrine cells (red), OFF bipolar cells (blue), and ON bipolar cells (yellow) across the depth of the VG3 plexus. d Histograms showing the distribution of synaptic input across the depth of the VG3 plexus. Left = absolute synapse number. Right = synapse density relative to VG3 arbor length. e Mean density of synapses relative to distance to tip of VG3 dendrite. Shaded region shows standard error for distance bin of 1840 dendrite tips. Z# indicates zones shown in (f). f Frequency of different synapse combinations found within dendrite zones shown in (e). Small pie chart includes dendrites with no synapses in black.
