The Pyloric Central Pattern Generator (CPG) is an ensemble of neurons in the Stomatogastric ganglion that produces a rhythmic motor pattern controlling the pylorus (the pyloric region of the foregut). There are some details that differ between species. This a description of the general properties of the pyloric CPG of decapod crustaceans.


Neuronal Circuit

Kernal of the pyloric CPG circuit showing the AB-PD group, the PD and LP cells. The small circles represent inhibitory synapses.

The pyloric CPG consists of 14 neurons composed of six major cell types; The anterior burster (AB), Pyloric Dilator (PD), lateral pyloric ( LP), ventricular dilator (VD), inferior cardiac (IC), and the pyloric neuron (PY).
