The minute eye movements of 4 sleeping subjects were studied with a piezo-electric strain-gauge transducer. The frequency and amplitude of ocular microtremor activity diminished during sleep. Activity increased after auditory stimulation and with the appearance of a K complex in the EEG. The ocular microtremor activity also increased with the onset of rapid eye movement (REM). Low amplitude 'micronystagmoid' movements were observed at intervals throughout sleep. In contrast to the changes observed during sleep, ocular microtremor activity did not diminish during hypnosis. The transducer was far more sensitive than the conventional EOG recording system.
使用压电应变计传感器对4名睡眠受试者的微小眼球运动进行了研究。睡眠期间，眼球微震颤活动的频率和幅度降低。听觉刺激后以及脑电图中出现K复合波时，活动增加。快速眼动（REM）开始时，眼球微震颤活动也增加。在整个睡眠过程中，间歇性地观察到低幅度的“微眼震样”运动。与睡眠期间观察到的变化相反，催眠期间眼球微震颤活动并未减弱。该传感器比传统的眼电图记录系统更敏感。
