Vividly stained with the fluorochrome Lucifer yellow, the retina ganglion cell in the central portion of the image below is extruding a multiple of processes. Closely associated dopamine-operated amacrine cells were counterstained with Texas Red.

Bipolar Cells of the Mouse Retina In the retina, bipolar cells are situated between photoreceptors and ganglion cells. They act, directly or indirectly (via amacrine cells), to transmit signals from the photoreceptors to the ganglion cells. Each bipolar cell can synapse with either rods or cones, but not both (hence the name “bipolar”). There are ten distinct types of cone bipolar cells in the mammalian retina, and only one type of rod bipolar cell (stained red in the image above).
A network of actin fibres (red) stretches between the green fluorescent contact points in this cell. It forms the cell sceleton and enables its movements.
