Synaptic input zones are uniformly distributed along the dendrites of most types of ganglion cells.
The NeuroLucida drawings in the upper panel are the dendritic morphologies of the G3, G5, G6, G7, G11, G12, G15, and G17 types of mouse RGCs characterized in the present study. The excitatory glutamatergic inputs (PSD95-GFP puncta) are indicated by red dots. Vertical projection of the same cells in the lower panel shows the depth of dendritic stratification in the inner plexiform layer (shaded area). Scale bar, 20 µm.
