Figure 7. ACh excitation is critical for fine‐scale motion detection in mouse DSGCs.

A, the spike response of an Hb9 neuron to 17 and 270 μm diameter moving white spots in the preferred and null direction (1 mm/s; intensity = 20 R^*/rod/s), under control conditions and in HEX. B, the average number of spikes of the preferred direction responses in the conditions shown in A (n = 7; ^* P < 0.005). The ACh component was estimated as the difference of spiking in control and HEX (dashed line).
