Red pigment concentrating hormone strongly enhances the strength of the feedback to the pyloric rhythm oscillator but has little effect on pyloric rhythm period
The neuropeptide, red pigment concentrating hormone (RPCH), strengthened the inhibitory
synapse from the lateral pyloric (LP) neuron to the pyloric dilator (PD) neurons in the pyloric …

Synaptic dynamics do not determine proper phase of activity in a central pattern generator
P Rabbah, F Nadim - Journal of Neuroscience, 2005 - Soc Neuroscience
Rhythmic motor activity often requires neuronal output to the muscles to arrive in a particular
sequence. At the pattern-generator level, this requires distinct activity phases in different …
