KINEMATICS OF EYE-MOVEMENT CONTROL

In this paper a kinematic description of the restrictions imposed on t he eye movements is presented. The restrictions arise from a pattern o f nonlinear interactions between desired changes in viewing direction and current eye position. It is shown that various reported relations between eye torsion and viewing direction can be derived by changing o nly the relative weights of the interaction terms. This descriptive sc heme may help to elucidate the control of eye torsion in the brainstem .
