Saccades and smooth pursuit eye movements are two different modes of oculomotor control. Saccades are primarily directed toward stationary targets whereas smooth pursuit is elicited to track moving targets. In recent years, behavioural and neurophysiological data demonstrated that both types of eye movements work in synergy for visual tracking. This suggests that saccades and pursuit are two outcomes of a single sensorimotor process that aims at orienting the visual axis.
扫视和平稳跟踪眼动是眼动控制的两种不同模式。扫视主要指向静止目标,而平稳跟踪则用于追踪移动目标。近年来,行为学和神经生理学数据表明,这两种眼动模式在视觉跟踪中协同作用。这表明扫视和平稳跟踪是旨在定向视轴的单一感觉运动过程的两种结果。
