Figure 6.
Respiratory rhythm in the presence of 100 µM FFA and 20 µM RIL. Continuous segments of the experiment showing control, FFA, recovery, and then FFA + RIL co-application, and finally FFA + RIL + 2 µM SP conditions in a mouse slice. SP rescued the rhythm after its cessation due to FFA + RIL. Examples of inspiratory bursts and XII output are shown with greater time resolution (lower panels).
