RPCH Modulation of a Multi-Oscillator Network: Effects on the
Pyloric Network of the Spiny Lobster. J. Neurophysiol. 85: 1424-1435, 2001. The neuropeptide red pigment
concentrating hormone (RPCH), which we have previously shown to
activate the cardiac sac motor pattern and lead to a conjoint gastric
mill-cardiac sac pattern in the spiny lobster Panulirus,
also activates and modulates the pyloric pattern. Like the activity of
gastric mill neurons in RPCH, the pattern of activity in the pyloric
neurons is considerably more complex than that seen in control saline.
This reflects the influence of the cardiac sac motor pattern, and
particularly the upstream inferior ventricular (IV) neurons, on
many of the pyloric neurons. RPCH intensifies this interaction by
increasing the strength of the synaptic connections between the IV
neurons and their targets in the stomatogastric ganglion. At the same
time, RPCH enhances postinhibitory rebound in the lateral pyloric (LP)
neuron. Taken together, these factors largely explain the complex
pyloric pattern recorded in RPCH in Panulirus.
