The motor rhythm of ventilation in hermit crabs and lobsters appears to be controlled by a pair of neurons, one in each half of the subesophageal ganglion. Their membrane potentials oscillate and upon depolarization and hyperpolarization elicit spiking in two pools of motor neurons on each side, without spikes in the oscillator neurons themselves. The fact that higher order (command) interneurons can control the rate of the oscillator by means of a smoothly graded input lends support to the idea that oscillator neurons respond periodically to a constant ionic stimulus.
寄居蟹和龙虾的呼吸运动节律似乎由一对神经元控制，食管下神经节的每一半各有一个。它们的膜电位振荡，去极化和超极化时会在每一侧的两组运动神经元中引发动作电位，而振荡神经元本身不会产生动作电位。高阶（指令）中间神经元能够通过平滑分级的输入来控制振荡器的频率，这一事实支持了振荡神经元会对恒定离子刺激做出周期性反应的观点。
