1.在寻找相关的快节奏在喉返（RL）呼气（E）活动，我们进行了频谱和相干分析双侧RL神经放电在54中丘去大脑，瘫痪猫。2.吸气（I）RL活动显示，在几乎所有的情况下，高频振荡（HFO，范围50-100 Hz），是双边相干的，也相干HFO在膈（PHR）活动。相比之下，在RLE放电中，仅在一小部分猫（6/54）中发现双侧相干节律（范围24-54 Hz）;在其他猫（48/54）中，即使自谱显示两侧存在类似的快节律，也不存在这种相干性。双侧RLE相干性与RLE活动的振幅增加和持续时间延长相关，例如通过迷走神经切断术或非充气去除阶段性肺牵张受体输入后发生的情况。3.因此，虽然连贯的快节奏是罕见的RLE放电，它们的发生在某些条件下表明参与这种活动的神经元之间的短时间尺度的相互作用的存在。这表明这种节律是神经网络的一般特征。
1. In a search for correlated fast rhythms in recurrent laryngeal (RL) expiratory (E) activities, we performed spectral and coherence analysis on bilateral RL nerve discharges in 54 midcollicular decerebrate, paralyzed cats. 2. Inspiratory (I) RL activities showed in almost all cases high-frequency oscillations (HFO, range 50-100 Hz) that were bilaterally coherent and also coherent to HFOs in phrenic (PHR) activities. In contrast, bilaterally coherent rhythms (range 24-54 Hz) in RLE discharges were found in only a fraction of the cats (6/54); in the other cats (48/54) such coherences were absent even though the auto-spectra showed the presence of similar fast rhythms on the two sides. The bilateral RLE coherences were associated with increased amplitude and prolonged duration of RLE activity, such as occurred following removal of phasic pulmonary stretch receptor inputs by vagotomy or by no-inflation. 3. Thus, although coherent fast rhythms are uncommon in RLE discharges, their occurrence under some conditions indicates the presence of short-time-scale interactions between neurons involved in this activity. This suggests that such rhythms are a general feature of neural networks.
