Figure 13. — Summary of bilateral pre-BötC optical perturbations of inspiratory frequency, amplitude of inspiratory phrenic activity, and T_I and T_E in the intact in situ preparations from VgluT2-Arch-GFP, Dbx1-Arch-GFP, and Sst-tdTomato-Arch-GFP (n = 8 each) Tg lines. A, Laser application significantly reduced inspiratory frequency monotonically in a laser power-dependent manner in all cases. These frequency–power relations were not statistically different among VgluT2-, Dbx1-, and Sst-expressing neuronal populations (one-way ANOVA: F_(2,21) = 1.51, p = 0.246). B, T_I did not significantly change (F_(3,22) = 0.69, p = 0.568). C, T_E increased in a laser power-dependent manner in all cases, which accounts for the progressive reductions in inspiratory frequency. D, The amplitude of phrenic inspiratory bursts was not significantly changed during laser application (F_(3,22) = 0.89, p = 0.462). Data are represented as the mean ± SD.
