Respiration, mastication, and locomotion are compared in terms of the contributions of events occurring at the motoneuron membrane and at premotoneuronal levels for the production of phasic gain changes of afferent effects. Data are presented which suggest that an inhibitory mechanism operating on limb motoneurons can prevent disruption of the locomotor pattern by proprioceptive input and that Ia inhibitory interneurons contribute to this rhythmic inhibition of both flexor and extensor motoneurons. Renshaw cell rhythmic activity during locomotion is described and discussed in terms of its possible role in gating of inputs to motoneurons.
本文从运动神经元膜及运动前神经元水平发生的事件对传入效应的相位增益变化产生的作用方面，对呼吸、咀嚼和运动进行了比较。所呈现的数据表明，作用于肢体运动神经元的一种抑制机制可防止本体感受输入对运动模式的干扰，并且Ia抑制性中间神经元对屈肌和伸肌运动神经元的这种节律性抑制有作用。文中描述并讨论了运动过程中闰绍细胞的节律性活动及其在运动神经元输入门控方面可能发挥的作用。
