Abstract

Visually-scored, non-Rapid Eye Movement (REM) sleep electroencephalographic (EEG) waveform activity for each 30-s sleep scored epoch-including the number of sleep spindles, the number of K-complexes, and the percentage of delta waves occupying the epoch-was correlated with H(2)(15)O positron emission tomography. Sleep spindle correlations included positive correlations in the thalamus and right hippocampus. K-complex correlations included positive correlations in the frontomedian prefrontal cortex and cerebellum. Delta wave correlations included negative correlations in the thalamus, frontomedian prefrontal cortex, dorsal pons, and primary visual cortex. Each pattern of correlations may suggest a functional significance for these waveforms that relates to a waking outcome.

摘要

对每个 30 秒睡眠评分时段的视觉评分、非快速眼动 (REM) 睡眠脑电图 (EEG) 波形活动进行评分，包括睡眠纺锤波的数量、K-复合波的数量以及占该时段的 delta 波的百分比——与 H(2)(15)O 正电子发射断层扫描相关。睡眠纺锤波相关性包括丘脑和右侧海马的正相关。K-复合波相关性包括额前正中前额叶皮质和小脑的正相关。Delta 波相关性包括丘脑、额前正中前额叶皮质、背侧脑桥和初级视觉皮层的负相关。这些相关性模式可能表明这些波形与清醒结果有关的功能意义。
