Coloured Fluorescence light micrograph of Neuron from stomatogastric ganglion (lobster, Homarus americanus). The stomatogastric nervous system (STNS) is composed of several ganglia in arthropods that controls the motion of the gut and foregut. The system is composed of the stomatogastric ganglion (STG), oesophageal ganglion and the paired commissural ganglia. The network of neurons acts as a central pattern generator. It is a common, laboratory studied neural network in arthropods and has become a model system for motor pattern generation because of the small number of cells (large nerve cells which can be reliably identified). In this image a neuron from the stomatogastric ganglion has been filled with Lucifer Yellow. Magnification x80 when shortest axis printed at 25 millimetres.
