The eye's fast jump between fixations

A saccade is the rapid, ballistic jump the eyes make to shift gaze from one point to another (among the fastest movements the body produces), separating the brief fixations during which vision actually takes in detail. Sparks's 2002 The brainstem control of saccadic eye movements describes how the superior colliculus and brainstem burst generators turn a desired gaze target into the precisely timed bursts that drive the eye to it. The referent is a discrete, high-velocity gaze shift, measured by its amplitude, peak velocity, and latency, and during the movement itself vision is largely suppressed.[1]
