Neural Mechanisms for the Production of the Lobster Pyloric Motor Pattern

In order to understand and explain the biological mechanisms underlying an animal’s behavior, we must investigate the structure and physiology of its nervous system. One form of behavior that is particularly amenable to physiological analysis is the class of rhythmic behaviors such as locomotion, respiration, mastication, copulation, and circulation (Delcomyn, 1980; Kristan et al., 1977). The behaviors are easily observed and quantified, and the components of the nervous systems involved in their production are usually straightforward to identify and manipulate experimentally. As a result of the work being done on several different rhythmic behaviors, general principles of nervous system organization and function are continuing to emerge (see Chapters 1, 4, 5 of this volume).
