The electrical activity of the posterior thalamic nuclear complex was studied in rats and related to the simultaneous hippocampal electro-oscillogram. Electrocorticographic tracings and spectral analysis showed that during attentive wakefulness the electro-oscillogram peaked at 8 Hz and in desynchronized sleep it oscillated at regular frequencies between 8 and 9 Hz. In quiet wakefulness, frequency was lower (around 6 Hz) and during synchronized sleep rhythmicity disappeared. The electrophysiological patterns during wakefulness and desynchronized sleep are proposed to be linked to the retrieval and combination of information for the generation of attention and dream content.
研究了大鼠丘脑后核复合体的电活动，并将其与同时记录的海马电图进行关联。脑电图描记和频谱分析表明，在警觉觉醒期间，脑电图在8赫兹时达到峰值，在去同步睡眠期间，它以8至9赫兹之间的规则频率振荡。在安静觉醒状态下，频率较低（约6赫兹），而在同步睡眠期间，节律性消失。觉醒和去同步睡眠期间的电生理模式被认为与信息的检索和组合有关，以产生注意力和梦境内容。
