研究了 Tritonia diomedea 颊运动神经元去极化后电位 (DAP) 的性质和作用。神经元 B5 表现出 DAP，其离子依赖性和 TEA 和 4-AP 的可修饰性表明与先前在胸膜起搏器神经元中描述的 DAP 相似。 DAP 的减少严重降低了这些神经元产生动作电位爆发的能力。某些其他运动神经元（B1 和 b6）由似乎源自突触的缓慢 DAP (SDAP) 重新激发。结论是，依赖于运动神经元活动的 DAP 有助于颊神经节运动输出的合成。
The nature and role of the depolarizing afterpotentials (DAPs) of buccal motoneurons of Tritonia diomedea were examined. Neuron B5 exhibits a DAP whose ionic dependence and modifiability by TEA and 4-AP suggest a similarity to the DAP previously described in pleural pacemaker neurons. Reduction of the DAP severely reduces the ability of these neurons to generate bursts of action potentials. Certain other motoneurons (B1 and b6) are reexcited by a slow DAP (SDAP) which appears to be of synaptic origin. It is concluded that DAPs, which are dependent upon motoneuron activity, contribute to the synthesis of motor output by the buccal ganglion.
