对丽蝇（Phormia regina）单个标签化学感应毛的化学和电刺激的电反应的各个部分的分析表明，尖峰电位的记录条件近似于其他类型的感觉细胞中进行的细胞内记录。大的正静息电位可能来自皮下细胞的基底膜和神经膜，而不是来自化学感应毛发基部的神经元。对通过单个化学感应毛发的极化电流的响应支持了这一分析。对类似极化电流的行为反应是由电流对相邻化学感应毛发基部神经元的作用引起的。报道的与化学感应毛发相关的两个化学感应神经元的神经相互作用可能是由于刺激溶液的物理化学属性而不是任何真正的神经相互作用。对响应化学刺激的初始神经脉冲潜伏期的观察表明，化学感应神经元通常没有自发的尖峰活动。
An analysis of the various parts of the electrical responses to the chemical and electrical stimulation of a single labellar chemosensory hair of the blowfly, Phormia regina, indicates that the recording conditions for the spike potentials approximate the intracellular recordings made in other types of sense cells. The large positive resting potential probably arises from the basement membrane of the hypodermal cells and neurilemma rather than from the neurons at the base of the chemosensory hair. The responses to polarizing currents passed through single chemosensory hairs support this analysis. The behavioral responses to similar polarizing currents are shown to result from the action of the current on the neurons at the bases of the adjacent chemosensory hairs. The reported neural interaction of the two chemosensory neurons associated with the chemosensory hair is probably due to the physical-chemical attributes of the stimulating solution rather than to any real neural interaction. Observations on the latency of the initial nerve impulse in response to chemical stimulation indicate that the chemosensory neurons are normally free from spontaneous spike activity.
