Adaptability and Variability in the Oculomotor System

We have been investigating the adaptive capabilities of a simple oculomotor system: saccadic eye movements. Saccades are rapid eye movements that take the line of gaze from one point to another very quickly, as when reading. Saccades are highly ballistic — once a saccade to a visual target has been programmed, the eyes will go to that target (or very nearly so) even if the target subsequently changes position.1 A further corrective saccade must then be made to bring the eyes to the target.
