Spike activation of the motoneurons innervating uropod muscles in crayfish is controlled by anaxonic interneurons located within the terminal (the 6th abdominal) ganglion. These neurons do not generate spikes either spontaneously at the resting potential level or in response to current injection of either polarity. Yet the change in the membrane potential of these non-spiking interneurons caused an increase or decrease in the discharge frequency of motoneuron spikes, depending upon the direction of the membrane potential change. These non-spiking interneurons within the terminal ganglion presumably integrate various descending command signals and select the adequate information to be gated to the motoneurons.
小龙虾中支配尾足肌肉的运动神经元的锋电位激活由位于终末（第6腹节）神经节内的无轴突中间神经元控制。这些神经元在静息电位水平既不自发产生锋电位，也不响应任何极性的电流注入。然而，这些不产生锋电位的中间神经元膜电位的变化会导致运动神经元锋电位发放频率增加或减少，这取决于膜电位变化的方向。终末神经节内的这些不产生锋电位的中间神经元大概整合了各种下行指令信号，并选择合适的信息传递给运动神经元。
