14.1 Goal of this Chapter

The goal of this chapter is to examine the cone and horizontal cell system using a qualitative visualization technique called phase plane analysis; this system will be discussed further in Chapter 28, “Models of the Retina.” The techniques presented here will be used again in Chapter 15, “Exploring the Fitzhugh-Nagumo Model.”
