Isolation of the disparity vergence late components

The “dual mode” theory for the control of disparity vergence eye movements states that two control components, a preprogrammed “initial” component and a feedback control “late” component, mediate the motor response. Previous experimental work has isolated and studied the initial component contribution, but little is known of the late component vergence response. Using a newly developed isolation technique, late component responses were separated from the initial component responses. It is hypothesized that a slow velocity late component does exist and can be isolated
