Local density of synaptic puncta across the RGC arbor. (a-d) The local density of synaptic puncta is determined by counting the number of puncta per dendritic segment. The length of the dendritic segment is determined for each cell by dividing the total length of the arbor by the total number of puncta: (a) raw image; (b) dendritic skeleton and puncta; (c, d) dendritic segments color coded according to synaptic density. Hot colors represent relatively higher puncta densities. (e) Plot of the proportion of segments bearing puncta for monostratified and P5 cells. Error bars = standard error of mean. (f) Plot of P/D for segments bearing puncta for monostratified and P5 cells.
