How a Ganglion Cell Detects Movement (VIDEO)
Caption
Ganglion cells preferentially form synapses with those amacrine cells whose dendrites run in the direction opposite -- seen from the ganglion cell - to the preferred direction of motion (amacrine cell on the rigt). A visual cue running from left to right activates (red) the ganglion cell via the synapses of the bipolar cells. A cue running from right to left makes the amacrine cell synapses to inhibit the ganglion cell (blue) before it is activated by the bipolar cells.
