Figure 2

Optogenetics. (A) Excitation spectra for ChR and Chrimson activators [figure 1E in Klapoetke et al. (2014)], and the response of flies expressing the gtAcr inhibitor to different wavelengths [figure 1A in Mohammad et al. (2017)]. (B) Schematic showing how optogenetic activation can mimic visual looming stimulus to evoke a jump-escape response. Diagrams adapted from A. Prokop: https://droso4schools.wordpress.com/about-us/. Experiment presented in Wu et al. (2016). (C) Activation of P1 neurons with ReaChR evokes a lasting courtship state, while activation of the P10 neurons elicits wing extension time-locked to stimulus (Inagaki et al. 2014). CPG, central pattern generator; VNC, ventral nerve cord.
