The purpose of this study was to test the hypothesis of the existence and independence of multiple generators of the sleep rhythms. Spatio-temporal analysis of the sleep EEG of 6 subjects was realised both visually and by multi-dimensional analysis of the parameters of spectral power (PS) and coherence (CH). Four results have been demonstrated: a relative decrease of the global CH during the transition from waking to deep sleep, with reappearance of high CH during paradoxical sleep (PS); (2) a negative correlation between the activities of frontal and occipital regions, mostly for alpha and theta frequencies; (3) a dominance of the activity of one hemisphere (the left here) during sleep, with a possible change of this dominance during paradoxical sleep; (4) a slow oscillation of power (SOP) with a periodicity of 1-5 min. variable according to subjects and sleep stages. These results suggest the existence of two partially independent groups of generators (anterior and posterior) for the slow frequencies of sleep.
本研究的目的是检验睡眠节律存在多个发生器且相互独立这一假设。对6名受试者的睡眠脑电图进行了时空分析，包括视觉分析以及对频谱功率（PS）和相干性（CH）参数的多维分析。已证实了四个结果：从清醒到深度睡眠过渡期间，整体CH相对降低，在异相睡眠（PS）期间高CH再次出现；（2）额叶和枕叶区域活动之间呈负相关，主要针对α和θ频率；（3）睡眠期间一个半球（此处为左侧）的活动占主导，在异相睡眠期间这种主导可能发生变化；（4）功率缓慢振荡（SOP），其周期为1 - 5分钟，因受试者和睡眠阶段而异。这些结果表明，存在两组部分独立的发生器（前部和后部）用于睡眠的慢频率。
