In humans and other primates, eye movements are made several times a second to place and hold images of objects of interest onto the central part of the retina, the fovea, where visual acuity is best. These eye movements fall into two main classes. Saccades are fast and brief movements, reaching peak speeds of … See more Starting an eye movement is often described as the outcome of a selection process that evaluates potential target locations in the visual field. This is only half the story. The transition from fixating to moving the eyes is … See more Neurons in several brain regions display the signatures of being involved in the control of fixation—elevated firing rates during maintained … See more Eye movements during fixation are not just a motor curiosity, but have substantial effects on visual perception and even on the control of other movements.
