Present concepts of oculomotor organization.

An introduction to the oculomotor system, which should provide a framework for the 10 anatomical reviews in the following chapters, this chapter describes the characteristics of the 5 basic types of eye movement and outlines the structures that are involved in the generation of each. Some common eye movement deficits, and concepts such as 'the neural integrator' and the 'velocity storage mechanism', for which anatomical substrates are still sought, are introduced.
