Aftereffects of skeletal- and mixed skeleto-fusimotor stimulation on the dynamic and static sensitivity of the muscle spindle afferents were investigated in anesthetized cats. After the concurrent contraction of both extra and infrafusal fibers resulting from the strong stimulation of the muscle nerve, the dynamic and static thresholds of the primary and secondary endings diminish in the responses of the passive muscle spindle to subsequent stepwise and triangular stretch. The discharge pattern of the afferent is also changed at the beginning of the linear stretch. The increment of the afferent's firing rate caused by the fusimotor stimulation is sometimes in accordance with that of the static response of the same afferent with the static elongation of the m. triceps surae by 10 mm.
在麻醉猫身上研究了骨骼和混合骨骼 - 肌梭运动刺激对肌梭传入纤维动态和静态敏感性的后效应。在肌肉神经受到强烈刺激导致肌外和肌梭内纤维同时收缩后，被动肌梭对随后的逐步和三角拉伸反应中，初级和次级末梢的动态和静态阈值降低。在直线拉伸开始时，传入神经的放电模式也会改变。由肌梭运动刺激引起的传入神经放电频率的增加，有时与同一传入神经在腓肠肌静态伸长10毫米时的静态反应的增加一致。
