English: Disruption of muscle contraction waves by activation of R26F05-Gal4 neurons with CsChrimson. A control (CsChrimson/+) or R26F05>CsChrimson larva was illuminated with 660 nm red light in the middle of peristaltic locomotion. “ON” or “OFF” in the movie shows the presence or absence of light application, respectively. In the larva expressing CsChrimson in R26F05-Gal4 neurons, muscle contraction waves were ceased upon light application. The larva resumed crawling after a second or so despite ongoing light illumination, likely due to adaptation of CsChrimson in response to red light [16].
