Fig. 6.

Illumination evoked responses of equimolar ChR2 H134R and NpHR3.0 (eNPAC). Evoked responses of eNPAC with 405, 488, 561, 594, and 639 nm single wavelength laser (a) illumination and (b) coillumination. Scale bars above individual experiments indicate current (vertical) and time (horizontal). For coillumination experiments, bars below recordings indicate time of illumination for the indicated color-coded wavelength. Black bars refer to coillumination with the color of the depicted traces. Activating laser intensities were 405 nm, $87\mathrm{mW}/{\mathrm{cm}}^2$; 488 nm, $296\mathrm{mW}/{\mathrm{cm}}^2$; and 561 nm, $146\mathrm{mW}/{\mathrm{cm}}^2$, and inactivating 594 nm coillumination intensity was $801\mathrm{mW}/{\mathrm{cm}}^2$.
