Someone might be surprised to see a book devoted to a nervous system belonging to animals of secondary interest (Crustacea) and which governs a relatively uninteresting motor behavior (the rhythmic movements of a digestive tract). However, the surprise disappears when it is known that the crustacean stomatogastric ganglion (STG) is probably the only central nervous system (CNS) in which almost all the neurons have been identified and almost all the synaptic relationships between these neurons are known. With this in mind, it is easy to understand why the study of this system has contributed enormously to the emergence and improvement of our basic concepts concerning cellular, synaptic and circuit mechanisms in general.
