Optomotor cycle
WebThe optomotor cycle is shown in Fig. 2.8. It illustrates the coordination of fixation, reflexive saccades, and voluntary control by the frontal lobe. It allows us to understand how deficits in saccade and/or in fixation control may contribute to poor reading. Here I will describe diagnostic eye movement tasks and the results of using them in ...

The optomotor response is essential for animals to correct unplanned course perturbations while navigating through their environment, such as current shifts around a swimming fish or air gusts around flying insects. The response is rapid and instinctual, with pure delay times of just 20-40ms for fruit flies in flight.
