Fig. 6. The pyloric rhythm in the STG is responsible for the pyloric-timed activity
of the CoG projection neuron MCN1 and the gastric mill protractor neuron LG
during the POC-triggered gastric mill rhythm. (Left) During the POC-triggered
gastric mill rhythm, MCN1 and LG exhibited pyloric-timed activity. (Middle)
When the pyloric rhythm was suppressed, by hyperpolarization of the pyloric
pacemaker neurons, the POC-triggered gastric mill rhythm persisted but the
activity of MCN1 and LG changed from pyloric-timed to tonic. (Right) After
releasing the pyloric pacemaker neurons from hyperpolarization, the pyloric
rhythm resumed and MCN1 and LG returned to exhibiting pyloric-timed
activity.
