In anaesthetized, spontaneously breathing cats and dogs extracellular recordings were made of the spontaneous activities of 28 single neurones with cardiac rhythm. Histological exmaination confirmed that the neurones were situated in the mediodorsal portion of the nucleus of the solitary tract. The neurones, which had already been analysed in respect to their pulse-rhythmical pattern27, were investigated by means of inspiration triggered histograms. The neurones could be grouped according to the respiratory modulations of their activities. Increased activities occurred during (a) the rise of the respiratory blood pressure wave, (b) the respiratory rest period, and (c) the inspiration. Three neurones did not exhibit respiratory modulation. The respiratory modulations of groups a and b were most probably caused by changing inputs from cardiovascular receptors in the course of respiration. It could be shown by adequate stimulation and elimination of the vagus nerves that the neurones of group c were influenced by lung inflation receptors as well as by cardiovascular receptors.
在麻醉状态下、自主呼吸的猫和狗身上,对28个具有心搏节律的单个神经元的自发活动进行了细胞外记录。组织学检查证实这些神经元位于孤束核的中间背侧部分。这些已经根据其脉搏节律模式进行过分析的神经元,通过吸气触发直方图进行了研究。这些神经元可根据其活动的呼吸调制进行分组。在以下情况中活动增加:(a) 呼吸血压波上升期间,(b) 呼吸静止期,以及 (c) 吸气时。三个神经元未表现出呼吸调制。a组和b组的呼吸调制很可能是由呼吸过程中心血管感受器输入的变化引起的。通过对迷走神经进行适当刺激和切断可以表明,c组的神经元受到肺扩张感受器以及心血管感受器的影响。
