Neurograms of proximal leg motor nerves were obtained during swimming in the shore crab. Whereas excitor motoneurones fire in bursts, the common inhibitor motoneurone discharges tonically with simultaneous spikes in all the motor nerves. The average firing frequency of the common inhibitor increases as the period of the swimming cycle decreases. Moreover, greater fluctuations of the firing frequency of the common inhibitor occurs within long rather than short swim cycle periods.
在岸蟹游泳过程中获取了近端腿部运动神经的神经图。兴奋性运动神经元呈阵发性放电，而共同抑制性运动神经元则持续放电，且所有运动神经同时出现尖峰。随着游泳周期时长的缩短，共同抑制性运动神经元的平均放电频率增加。此外，共同抑制性运动神经元放电频率的波动在较长而非较短的游泳周期内更大。
