(A–F) Individual data for the in situ WHBP of P31 rats with bilateral GtACR2 expression in the preBötC, presented as group data in Figure 3. (A) Individual data for respiratory frequency, and PNA burst inspiratory duration and amplitude, presented as group data in Figure 3C. During prolonged 20 Hz preBötC photoinhibition, PNA bursts were transiently silenced after each light pulse as shown on Figure 3H. (B) The duration of PNA burst silences during an individual burst decreased with continued photoinhibitory pulses. The abscissae shows successive PNA bursts with the duration of silences on the ordinate, starting from the first pulse of light that impacted the analysed PNA burst. (C) Individual data for VNA measured outside (non-resp) the inspiratory/post-inspiratory activities, and for the post-inspiratory component of VNA, presented as group data in Figure 3D. (D) Individual data for HR, presented as group data in Figure 3E. HR decreased in steps at the beginning of preBötC photoinhibition, the first step being reached earlier in the high-frequency preBötC photoinhibitions. Similarly, the time to reach maximum bradycardia from the beginning of preBötC photoinhibition trials was shorter with high-frequency preBötC photoinhibition. The time to return to basal HR, during the recovery period, was only shorter for the 50 Hz photoinhibition compared to other frequencies. (E) Individual data for mean tSNA, presented as group data in Figure 3F. The mean tSNA decrease was more pronounced for 10 Hz and 20 Hz preBötC photoinhibition, both in amplitude and duration. (F) Individual data for mean PP, presented as group data in Figure 3G, and for pulse pressure. PP decrease duration for 10 Hz, 20 Hz and 50 Hz preBötC photoinhibitions followed the same timing as mean tSNA decrease, but not for 5 Hz preBötC photoinhibition, likely due to the decreased RespSNA and Traube-Hering waves that lasted the entire 5 Hz preBötC photoinhibition period. (G) Linear regression analysis of data, showing that the overall cardiac parasympathetic drive elicited by preBötC photoinhibition is unrelated to the presence of respiratory activity. In contrast, the vasomotor sympathetic tone is directly related to it, suggesting different mechanisms of action. Group data are presented as mean ± SEM; Friedman repeated measures analysis of variance on ranks followed with pairwise multiple comparison Tukey test, one-way repeated measures ANOVA followed with post hoc Holm-Sidak multiple-comparison test, paired student’s t-test or Wilcoxon signed rank test, performed on raw data, as shown on the associated source data and detailed statistics; *p<0.05, **p<0.01, ***p<0.001, photoinhibition vs. control and recovery conditions; # p<0.05, ## p<0.01, ### p<0.001, between photostimulation frequencies; ‡ p<0.05, ‡‡ p<0.01, ‡‡‡ p<0.001, intra-photostimulation frequency vs. max change.
