Separable channels of optogenetic excitation. (a) Voltage traces showing that ChR2 and VChR1 can be selectively activated by 406- (1.2 mW mm−2) and 589-nm (2.3 mW mm−2) light, respectively. Trains of 5-ms light flashes were delivered at 5 Hz. (b) Population data comparing activation of ChR2 by 406- and 589-nm light at three different light intensities (n = 7). Trains of 5-ms light pulses were delivered at 5 Hz. (c) Population data comparing activation of VChR1 by 406- and 589-nm light at three different light intensities (n = 10). Values are mean ± s.e.m.
