The focus of attention in this chapter will be upon precision of a pacemaker system. We begin with the type model defined in Chapter 5. This will be followed by consideration of many variants, including both modifications of the type model, achieved by changing the values of its parameters, and more extreme alterations, involving new sorts of parameters entirely. An examination of how and why these variations influence precision of the pacemaker system proves to be a convenient vehicle for exposing further details about internal functioning of models of this general class. It serves, in addition, to demonstrate that the type model is by no means an atypical example of its class. Comparable functioning of the models arises even with a wide range of parameter values and formulations, and no trick or “fine tuning” was involved in defining the type model. Finally, this chapter also provides the kind of background which guided me in the choice of parameter values for specific models, to be described subsequently, where the objective is to mimic particular details of the wake-sleep cycle observed of a given species of animal. The general objective here, then, is a further understanding of the pacemaker models, purely as model systems.
