Since an inverse relationship between waking and REM sleep eye movements (EMs) has been found with respect to frequency, amplitude and direction of EMs, we evaluated variations in the percentages of horizontal rapid eye movements (REMs) during REM sleep after having increased rightward saccades during waking by means of a unilateral tachistoscopic visual test administered prior to sleep. In another condition subjects were given the same 4 h testing condition prior to sleep, the only difference being that they were instructed not to move their gaze; therefore only "attentional movements" were possible. This condition served as a control for the role of oculomotor activity in the complementary relationship between waking and REM sleep eye movements. The actual increase of rightward saccades during waking resulted in a significant decrease of rightward REMs. This effect has been observed only in the condition in which rightward eye movements were increased and it is specific for REMs of amplitude similar to those which were increased during waking by the lateralized test.
由于已发现清醒时与快速眼动（REM）睡眠时的眼球运动（EMs）在频率、幅度和方向上呈反比关系，我们通过在睡眠前进行单侧速示视觉测试来增加清醒时向右的扫视，进而评估REM睡眠期间水平快速眼动（REMs）百分比的变化。在另一种情况下，受试者在睡眠前接受相同的4小时测试条件，唯一的区别是指示他们不要移动目光；因此只可能出现“注意力性运动”。此条件作为动眼神经活动在清醒与REM睡眠眼球运动互补关系中作用的对照。清醒时向右扫视的实际增加导致向右REM显著减少。仅在向右眼球运动增加的条件下观察到了这种效应，并且它特定于与通过单侧测试在清醒时增加的幅度相似的REM。
