Fig. 3. Light stimulation evoked premature low-frequency and high-amplitude (LFHA) contraction of muscle strips in Kit-ChR2(+) mice. (A, B) Light stimulation induced premature LFHA contractions in muscle strips in Kit-ChR2(+) mice, but not in Kit-ChR2(–) mice. The green arrow represented the high-frequency and low-amplitude (HFLA) contractions and the golden arrow represented LFHA contractions. The blue rectangles represented the light stimuli. (C, D) Quantification and comparison of characteristics of spontaneous LHFA in mice of both groups. (E-G) The ratio of LFHA contractions/light stimuli in mice of both groups. *P < 0.05, ****P < 0.0001.
