在安静睡眠(Q)、快速眼动睡眠(R)和清醒状态(W)时，对19个健康足月进行连续双极脑电图记录。计算双侧额-中央（FC）、中央-顶叶（CP）、顶叶-枕叶（PO）和颞叶（TT）的谱功率。测定脑内biFC、biCP、biPO和biTT位置以及左、右脑内FC-PO和TT-PO组合的一致性。CP衍生的功率在0.4 ~ 12/s时，Q值最高。一般来说，Q的功率比R的高。在大多数推导中，Q和R的功率是并行的。W的行为是不同的。在8/s之前，W的功率介于Q和R功率之间。从10/s开始，它变得最高，特别是在TT和FC衍生中。PO功率低。最高相干值出现在最低频率。在8/s以内，bbic、biCP和biPO脑内相干性在R期最高，通常在Q期最低。在α - β范围内，相干性在Q期最高，在R或W期最低，各阶段间差异不大。在所有阶段BiPO相干性都非常高。BiTT和半球内相干性较低，一致性较差。这些数据表明，大脑波区域之间的theta-delta活动高度同步，特别是在R期。我们假设新生儿theta-delta活动的活跃共同发生器位于后侧区域，表明这些区域的自主性较弱，相互依赖性更强，尤其是在R期。
Continuous, bipolar EEG recording was performed in nineteen healthy full-terms during quiet sleep (Q), REM sleep (R) and wakefulness (W). Spectral power was calculated for the bilateral fronto-central (FC), centro-parietal (CP), parieto-occipital (PO) and temporal (TT) derivations. Coherence was determined for the interhemispheric biFC, biCP, biPO and biTT locations, as well as for the left and right intrahemispheric FC-PO and TT-PO combinations. Power was highest in Q in the CP derivations at 0.4-12/s. Generally, power was higher in Q than in R. In most derivations, Q and R power ran parallel. W power behaviour was different. Up to 8/s, power in W was intermediate between Q and R power. From 10/s, it became highest, particularly in the TT and FC derivations. PO power was low. Highest coherence values occurred in the lowest frequencies. Up to 8/s, biFC, biCP and biPO interhemispheric coherences were highest in R and usually lowest during Q. In the alpha-beta range, highest coherences occurred during Q and lowest during R or W, without much variance between stages. BiPO coherences were remarkably high during all stages. BiTT and intrahemispheric coherences were low and less consistent. These data suggest high synchronization of theta-delta activity between biPO regions, particularly during R. We hypothesize active common generators of neonatal theta-delta activity in the posterior regions, indicating less autonomy and more interdependent behaviour of these areas especially during R.
