We have analyzed neural brainstem mechanism for rapid eye movements (saccades). The superior colliculus (SC) has been known to be involved in controlling saccade, but neural mechanism of triggering saccade has been kept unrevealed for a long time. This study has shown the reciprocal relationship between mechanisms of generation of saccades and visual fixation in the SC, and that this reciprocity itself is deeply involved in triggering mechanism of saccades.

我们分析了快速眼动（扫视）的神经脑干机制。上级丘（superior colliculus，SC）参与了眼跳的控制，但触发眼跳的神经机制一直未被揭示。本研究表明，在SC的眼跳和视觉注视的产生机制之间的相互关系，这种互惠本身是深参与眼跳的触发机制。
