Human cortical potentials associated with rapid eye movements (REMs) during REM sleep were recorded in 6 normal young adults by using the averaging technique. The potentials were compared with those recorded during voluntary saccades in the waking state in a dark or an illuminated room. A positive potential of relatively long duration with peak latency of about 200 msec and a wide spread bilateral distribution and of highest amplitude in the mid-parietal area appeared only during REM sleep. It is suggested that this positive potential is phasic EEG activity appearing in association with REMs during REM sleep in man. Comparison of this positive potential with P300s induced by task-irrelevant visual stimuli disclosed that they resemble each other. The possibility was discussed that this positive potential occurring in association with REMs during REM sleep is indeed a P300 appearing in response to visual images in dream.
通过使用平均技术,在6名正常年轻成年人中记录了快速眼动睡眠(REM睡眠)期间与快速眼动(REMs)相关的人类皮质电位。将这些电位与在黑暗或光照房间的清醒状态下自愿性扫视期间记录的电位进行比较。仅在REM睡眠期间出现了一个持续时间相对较长、峰值潜伏期约为200毫秒、双侧分布广泛且在顶叶中部区域振幅最高的正电位。提示该正电位是人类REM睡眠期间与REMs相关出现的相位性脑电图活动。将该正电位与由任务无关的视觉刺激诱发的P300进行比较发现,它们彼此相似。讨论了REM睡眠期间与REMs相关出现的这种正电位实际上是对梦中视觉图像做出反应而出现的P300的可能性。
