All vision, including reading this sentence, depends on a constant
series of infinitesimal jumps by the eyeball that centers the retina
on target objects--words or phrases in the case of reading. Such
jumps, or saccades, are critical to vision because only the small
central region of the retina, called the fovea, produces the clear
image necessary for perception. Such saccades take place several
times a second and are generated within a brain region known as the
frontal eye field (FEF).
