We have investigated the power spectral density (PSD) characteristics of spontaneous neuronal activities during paradoxical sleep (PS), including phasically firing PGO-on and tonically discharging type I-R neurons in the pontine tegmentum. The PSD of lateral geniculate PGO waves and blood pressure (BP) were also examined. During PS, the PSD of PGO-on neurons and PGO waves showed an almost white noise-like pattern, while that of TI-R neurons and BP exhibited a 1/f spectrum. It appears, therefore, that the neuronal and autonomic slow fluctuations found in the 1/f spectrum during PS are not driven by the PGO wave system.
我们研究了异相睡眠（PS）期间自发神经元活动的功率谱密度（PSD）特征，包括脑桥被盖中相位性发放的PGO-on神经元和持续性放电的I-R型神经元。还检测了外侧膝状体PGO波和血压（BP）的PSD。在PS期间，PGO-on神经元和PGO波的PSD呈现出几乎类似白噪声的模式，而I-R型神经元和BP的PSD呈现出1/f谱。因此，似乎在PS期间1/f谱中发现的神经元和自主神经的缓慢波动并非由PGO波系统驱动。
