p. 404. The moving eyelocked

  • Michael Land

Abstract

Why does our eye movement system not allow gaze to move continuously? ‘The moving eye’ describes how information is taken in during fixations and how saccades move the eyes as fast as possible to change the fixation point. The image is stabilized by the vestibular-ocular reflex where the eye-in-space direction (gaze) is equal to the eye-in-head direction plus the head-in-space direction. Each eye is moved by six muscles that both rotate the eye and help to keep it suspended in the orbit. What determines where we look? Do we know where we are looking? In many activities it takes time to process visual information before it can be converted to motor behaviour.
