摘要: The near-visual response consists of concomitant changes in accommodation, vergence, and pupil size. All three these motor systems share a common organization phasic-tonic control that characterizes their transient sustained responses. This dual-control for accommodation vergence is indicated by open-loop decay time constants, which increase with closed-loop stimulus duration (Schor, 1979; Schor et al., 1986a). A has also been interpreted from observations pupillary escape, occurs large but not small initial size (Sun Stark, 1983).
