Pursuit-Dependent Distribution of Vergence Among the Two Eyes

  • Casper J. Erkelens


Recordings of eye movements show that fixations of monocular and binocular details of a moving stereogram induce different smooth eye movements. Simulations show that such eye movements cannot be explained by existing models of smooth pursuit and vergence. Examination of their dynamics shows that the smooth eye movements are composed of voluntary smooth pursuit and involuntary vergence. The distribution of smooth pursuit among the two eyes is fixed, however, the distribution of vergence is adjustable. Distribution of vergence depends on the eye that fixates the pursued target. The consequence of the adjustable distribution of vergence is that the oculomotor system uses eye-of-origin information of the pursued target for the control of vergence.
