A polysomnography was performed on nine rabbits with electrodes chronically implanted at the sensorimotor and visual corticies and hippocampus. The physiological sleep of the rabbits was divided into three stages: awake (W), slow wave sleep (SWS) and REM sleep (REM). For autocorrelation and power spectrum analyses, a transitional zone (T) from W to SWS was added to the fundamental three stages. No essential differences between the mean frequencies of the cortical and hippocampal EEGs were seen. The mean frequencies of hippocampal EEG were as follows: 6.4 in W, 5.4 and 2.4 in T, 2.2 in SWS and 7.3 Hz in REM. The mean peak frequency of hippocampal EEG during REM was significantly higher than that during W.
对9只兔子进行了多导睡眠图检查，电极长期植入其感觉运动皮层、视觉皮层和海马体。兔子的生理睡眠分为三个阶段：清醒（W）、慢波睡眠（SWS）和快速眼动睡眠（REM）。为了进行自相关和功率谱分析，在基本的三个阶段中增加了一个从W到SWS的过渡区（T）。皮层和海马脑电图的平均频率之间未发现本质差异。海马脑电图的平均频率如下：W期为6.4，T期为5.4和2.4，SWS期为2.2，REM期为7.3赫兹。REM期间海马脑电图的平均峰值频率显著高于W期间。
