Phasic respiratory influences on late reflex discharges in the limb and lower intercostal nerves--electrophysiological analogs of somesthetic and acoustic startle reflexes (SR)--were studied in unanesthetized (decerebrated) or chloralose-anesthetized cats. The integrated values of the SR in both types of nerves always essentially decreased during inspiratory phase (by 28-58% on the whole) compared to those during expiratory phase. Data obtained evidence that this respiratory modulation of the SR occurs mainly at the brainstem level. The modulation of the limb SR is presumably due to a suppression of the reflex transmission only during the inspiratory phase. Trends and temporal development of SR modulations during the whole respiratory cycle has shown that there are distinct differences in reticular mechanisms underlying the modulation in the limb and intercostal reflexes as well as in organization of the corresponding reticular centre.
在未麻醉（去大脑）或水合氯醛麻醉的猫中，研究了相位性呼吸对肢体和肋间下神经晚期反射放电的影响——本体感觉和听觉惊吓反射（SR）的电生理类似物。与呼气期相比，在吸气期，两种神经中SR的积分值总体上总是显著下降（总体下降28%-58%）。获得的数据表明，SR的这种呼吸调制主要发生在脑干水平。肢体SR的调制可能仅在吸气期是由于反射传递的抑制。整个呼吸周期中SR调制的趋势和时间发展表明，肢体和肋间反射调制背后的网状机制以及相应网状中心的组织存在明显差异。
