Eye movements in 6 healthy men and women were studied for recurrent patterns during REM sleep. The REM periods of nocturnal polysomnograms, on 2 consecutive nights, were analyzed in each subject. A discrete scale from 1 to 8 was used to record each eye position. The total number of recorded eye positions for the 2 nights of testing varied from 1314 to 3006. The distributions of eye movement were similar for males and females, for both nights of testing for each subject, among individual REM periods, and between subjects. This was in spite of marked differences in the number and length of REM periods, and in the number of eye movements per minute of REM sleep. In 5 of 6 subjects there was a marked tendency for the eyes to move between the 2 opposite lateral positions. Regardless of the eye position, the opposite movement was generally most likely, with an underlying tendency to return to the most opposite of the two lateral positions. In the remaining subject the opposite movement was also favored, but in this subject eye movements were more likely to be vertical rather than horizontal. Our data suggest that eye movements in REM sleep are organized in complex recurring patterns, with marked similarities between subjects. The significance of these patterns and the significance of deviations from these patterns require further study.
对6名健康男性和女性在快速眼动睡眠期间的眼球运动进行了研究，以寻找反复出现的模式。在每位受试者中，对连续两晚的夜间多导睡眠图的快速眼动期进行了分析。使用从1到8的离散量表记录每个眼睛位置。两晚测试记录的眼睛位置总数在1314到3006之间。在每个受试者的两晚测试中、在各个快速眼动期之间以及在受试者之间，男性和女性的眼球运动分布相似。尽管快速眼动期的数量和时长以及快速眼动睡眠每分钟的眼球运动数量存在显著差异，但情况依然如此。在6名受试者中的5名中，眼睛有明显倾向在两个相对的外侧位置之间移动。无论眼睛处于什么位置，相反方向的移动通常最有可能，并且有回到两个外侧位置中最相反位置的潜在倾向。在其余一名受试者中，相反方向的移动也更受青睐，但在该受试者中，眼球运动更可能是垂直而非水平的。我们的数据表明，快速眼动睡眠中的眼球运动以复杂的反复出现的模式组织起来，受试者之间存在明显的相似性。这些模式的意义以及与这些模式的偏差的意义需要进一步研究。
