采用两个音高和概率不同的奇怪范式，比较清醒和两个睡眠阶段的事件相关电位(ERPs)。使用持续记录眼睛和身体运动的睡帽，9名受试者识别了REM和NREM睡眠阶段。N1出现的时间较晚，睡眠时的P2较清醒时大。在这两个睡眠阶段，对不常用音调的NT都较大。在REM睡眠中，命运负波与不频繁音相比明显增大。我们认为，在快速眼动阶段，听觉的表征是最重要的。事件相关电位成分潜伏期的延长表明，外界感觉刺激的处理可能会延迟。
USING an oddball paradigm with two tones differing in pitch and probability, event-related potentials (ERPs) were compared during wake and two sleep stages. REM and NREM sleep stages were identified in nine subjects using the Nightcap which continuously records eye and body movements. The N1 occurred later and the P2 was larger during sleep than when awake. The NT to the infrequent tones was larger during both sleep stages. A fate negative wave was significantly larger to infrequent tones during REM sleep. It is concluded that representations of auditory, during the REM phase. The prolonged latency of the ERP components indicates that processing of external sensory stimuli may be delayed.
