Rapid Nonconjugate Adaptation of Vertical Voluntary Pursuit Eye Movements
Abstract
The precise yoking of the two eyes during vertical eye movements is normally preserved throughout life. This preservation is due in part to adaptive processes that adjust the relative neural innervations sent to each eye's extraocular muscles (nonconjugate adaptation). This behavioral study investigates adaptive processes that maintain conjugacy along the vertical meridian during three types of ocular motor behavior: voluntary pursuit, saccade, and steady fixation. Binocular yoking was quantified by binocular recordings of vertical eye position (dual-Purkinje eye tracker) while vertical eye movements were monocularly stimulated. Properties of nonconjugate adaptive processes were inferred from changes in pre- and post-adaptation binocular yoking.
