Summary of effects of SP (control, 0.1, 1, 5 μM) on gill and buccal burst frequency (min−1) (A) and lung burst frequency (B) for pre-metamorphic (unfilled circles) and post-metamorphic (filled circles) brainstems. Gill and buccal burst frequency was unaffected by SP whereas lung burst frequency increased significantly. *P<0.05 compared with control (Dunnett’s test).
