Morphology of a polyaxonal amacrine cell tracer coupled to G1 ganglion cells. A: Camera-lucida drawing shows the entire dendritic/axonal arbor of a Neurobiotin-injected polyaxonal amacrine cell with soma/dendritic morphology similar to those coupled to G1 ganglion cells. Gray somata represent cells that appear coupled to this Neurobiotin-injected polyaxonal cell. B: High-magnification micrograph showing dendritic specializations of the injected polyaxonal cell (asterisk). Dendrites display relatively large swellings (open arrows) and spines (arrowheads), whereas axons display small swellings at regular distances (arrows). C: Photomicrograph showing the proximal soma/dendritic region of the injected polyaxonal cell drawn in panel A; asterisk marks the injected soma. This amacrine cell shows coupling to amacrine cells (open arrows) and ganglion cells (1–4 here and in insets) whose soma size and shape resemble those of G1 ganglion cells. a, axon. Scale bars = 100 μm in A–C; 50 μm in C insets.
