Fig. 5. (A) Simultaneous extracellular recordings from an abdominal wall muscle (Ab) and frontal ganglion (FG) efferent nerve (MPN) of pre-moult fifth instar larvae, showing full synchrony between the ventilation and the FG patterns. (B) New bursting pattern after cutting the recurrent nerve. (C) An independent FG pattern, similar to the in vitro preparation, emerges after disconnecting both frontal connectives.
