Changes of ΔCa2+ (F340/F380) under the stimulation of test lights. (a) The change curve of F340/F380 when SGCs are irradiated by single-pulse lights (453 nm, 300us) with 5.3 mJ/cm2, 38.3 mJ/cm2, 72.4 mJ/cm2, and 107.1 mJ/cm2 in turn. The red bars represent the onset time of each single light stimulus, before which there is no test light irradiation. (b) The change curve of F340/F380 when SGCs are stimulated by 453 nm, 810 nm, and 453 nm pulsed lights in turn. Calcium imaging speed is 2-5 s and excitation light switching speed is 2 ms. The light-blue area is the error value distribution range of the corresponding curve. (Data are represented as mean ± SEM)
