The static discharge rate of Renshaw cells (studied in deafferented, intercollicularly decerebrate cats) has a nonlinear dependence on the frequency of trains of stimulus impulses to alpha-motor axons in the ventral root. This dependence is well described by a rectangular hyperbola that approaches saturation with increasing stimulus frequency. The tendency to saturate is independent of the number of motor axons exciting a Renshaw cell. On average, the stimulus frequency at which the discharge rate reaches half its saturation value lies between 10 and 15 Hz. The effect of Renshaw cell activity -- measured as the antidromic inhibition of individual alpha-motoneurons -- reflects the forms of the static frequency characteristics. An electric circuit analog of the Renshaw cell membrane is presented which serves to explain the qualitative features of the static input-output relations; the nonlinearity is the result of synapses with linear properties acting together at the cell membrane.
（在去传入神经、中脑间切断脑桥的猫身上研究的）闰绍细胞的静态放电率，对腹根中α运动轴突刺激脉冲串的频率呈非线性依赖关系。这种依赖关系可用一条矩形双曲线很好地描述，随着刺激频率增加，该双曲线趋近于饱和。饱和趋势与兴奋闰绍细胞的运动轴突数量无关。平均而言，放电率达到其饱和值一半时的刺激频率在10至15赫兹之间。闰绍细胞活动的效应——以单个α运动神经元的逆向抑制来衡量——反映了静态频率特性的形式。文中给出了闰绍细胞膜的电路模拟，用以解释静态输入-输出关系的定性特征；非线性是细胞膜上具有线性特性的突触共同作用的结果。
