Fig. 5. Spontaneous firing for each cell class comparing photosensitive and light-insensitive neurons.

Fig. 5

There is no difference between photosensitive and light-insensitive neurons within the OFF-cell population, while spontaneous firing of the light-insensitive ON-cells was slightly greater. *p < 0.05 compared to photosensitive neurons (Wilcoxon’s signed ranks test). Data presented as mean + SEM.
