Light-induced spiking in the vf-Chrimson-expressing interneurons at optostimulation protocol of 20 stimuli, each of 0.5 ms pulse widths, at $\lambda =565\mathrm{nm}$, (a) at $I=2.6$, 2.6. 4.9, 4.9, 4.9, 4.9, 4.9, and $8\mathrm{mW}/{\mathrm{mm}}^2$ and $g_0=0.5$, 0.4, 0.34, 0.35, 0.41, 0.42, 0.55, and $0.54\mathrm{mS}/{\mathrm{cm}}^2$, respectively; (b) at $I=2.2\mathrm{mW}/{\mathrm{mm}}^2$ and $g_0=0.5\mathrm{mS}/{\mathrm{cm}}^2$, at indicated frequencies. Upper and lower frequency labels indicate output spiking frequency and input stimulation frequency, respectively.
