Two-photon excitation of channelrhodopsin-2 at saturation

We demonstrate that channelrhodopsin-2 (CR), a light-gated ion channel that is conventionally activated by using visible-light excitation, can also be activated by using IR two-photon excitation (TPE). An empirical estimate of CR's two-photon absorption cross-section at λ = 920 nm is presented,...
