Fig. 8. (A) Simultaneous extracellular recordings from an abdominal wall muscle
(Ab) and two frontal ganglion (FG) nerves (FC and MPN), showing full synchrony
between the ventilation and the FG patterns at the time of wing expansion. (B)
Uncoupling of FG and ventilation patterns generated by puncturing a hole in
the inflated gut. The FG rhythm resembles feeding/air-swallowing pattern. The
boxed areas on the right panels are played (left) at a higher sweep speed.
