Stomatogastric ganglion

The neurons comprising the stomatogastric ganglion have cell bodies located dorsal to the stomach within the lumen of the opthalmic artery.

[5] The electrical and chemical synaptic connections between all of the STG neurons have been fully mapped and characterized, forming a complete wiring diagram (also called a connectome).

[5] Neural activity in the stomatogastric ganglion produces rhythmic movements of the gastric mill and pyloric region of the digestive system.

[6] Neural circuits within the STG are prominent examples of central pattern generators, and their rhythm-generating properties have been studied in detail.

[9] These neuromodulators, such as serotonin, dopamine, proctolin, FLRFamide-like peptides, and red pigment-concentrating hormone (RPCH) can change the speed and form of the rhythmic activity.
