Cyclic changes of reflex discharges in phrenic, external and internal intercostal and lumbar nerves evoked by electrical stimulation of the superior laryngeal nerve were investigated in cats under light nembutal anaesthesia. Intensity of discharges and their latency varied in different nerves during the respiratory cycle. Reflex discharges of the greatest intensity with the shortest latency appeared at the end of the inspiratory or at the beginning of the expiratory phase in lumbar and internal intercostal nerves. Significant or complete depression of reflex discharges was observed before the inspiratory phase in these nerves. In contrast, reflex discharges in the phrenic and external intercostal nerves appeared only during the inspiratory phase and their intensity increased towards the end of this phase. Pronounced modulation of reflex discharges depended directly on changes in the respiratory centre excitability.
在轻度戊巴比妥麻醉下的猫中，研究了由喉上神经电刺激诱发的膈神经、肋间外肌和肋间内肌以及腰神经反射放电的周期性变化。在呼吸周期中，不同神经的放电强度及其潜伏期各不相同。腰神经和肋间内肌神经在吸气末期或呼气初期出现强度最大、潜伏期最短的反射放电。在这些神经的吸气期之前观察到反射放电明显或完全抑制。相比之下，膈神经和肋间外肌神经的反射放电仅在吸气期出现，且其强度在该期结束时增加。反射放电的明显调制直接取决于呼吸中枢兴奋性的变化。
