Abstract

Presentation Description : In the real world, to foveate most targets in 3D space, we must make disconjugate eye movements in which the left and right eye move with unequal amplitudes. The neural strategy used to execute these eye movements is still not well understood, and two different models have been proposed. The Helmholtz model proposes that both eyes move independently, and that ocular coordination is a learned behavior in which each eye foveates independently. The Hering model proposes that the two eyes move as a yoked pair for both conjugate and vergence eye movements. Previous experiments performed in different brain areas involved in the control of conjugate and vergence eye movements have lent support to both models. Our recent neurophysiological studies in the rhesus monkey provide further evidence favoring the Hering model in the control of conjugate and vergence eye movements.

This is an abstract that was submitted for the 2018 ARVO Annual Meeting, held in Honolulu, Hawaii, April 29 - May 3, 2018.
