Fig. 4. Periodic light stimulation enhanced the inherent frequency of low-frequency and high-amplitude (LFHA) contractions of muscle strips in Kit-ChR2(+) mice. (A, B) Isometric force recordings of colonic muscle strips in response to the periodic light stimulation in mice of both groups. The blue rectangles represented the light stimuli. (C, D) Effect of the periodic light stimulation on numbers of LFHA contractions and area under the curve in different groups. (E-G) Effect of the periodic light stimulation on characteristics of LFHA contractions in different groups. *P < 0.05, ****P < 0.0001.
