5-HT3 receptor antagonists increase frequency and episodicity. Integrated traces of XII respiratory motor output are shown before (left) and after (right) bath-application of tropisetron (50 μM) (A) or MDL72222 (50 μM) (B). Bath-application of tropisetron or MDL72222 for 120 min increased burst frequency (C) and bursts/episode (D). Symbols: *P<0.05 compared to controls (shown in Fig. 2B, 2D) at that time point; †P<0.05 for drug effect; values which differ significantly (P<0.05) from the baseline value are indicated by a solid symbol.
