一个比较新的研究外周嗅觉事件的电生理技术是记录持续的负电位从嗅上皮。这种方法正在迅速取代记录嗅神经或嗅球多纤维放电的旧技术。因此，通过在几种条件下同时记录神经和粘膜，研究了两种方法的结果相互关联的程度。虽然大多数情况下是平行的，但发现两种措施之间存在一些差异，它们的响应最大值并不总是在时间上一致。它们的振幅并不总是相关的。某些刺激减少随后的粘膜反应，但不是神经。重复刺激有时会产生类似的差异。最后，这两个反应不是线性相关的刺激强度或流速的函数。然而，由于讨论的原因，很难得出结论，这些差异必然反映不利的可靠性，粘膜电位作为标准措施的外周嗅觉活动。然而，在对粘膜电位有更透彻的了解之前，不应明确地将其作为标准测量。
A comparatively recent electrophysiological technique for studying peripheral olfactory events is to record sustained negative potentials from the olfactory epithelium. This method is rapidly replacing the older technique of recording multifiber discharges from the olfactory nerve or bulb. Therefore, the extent to which the results from the two methods correlate with each other was studied by simultaneously recording from the nerve and from the mucosa under several conditions. Although most often parallel, some differences between the two measures were found. Their response maxima did not always temporally coincide. Their amplitudes did not always correlate. Certain stimuli reduced subsequent mucosal responses but not the neural. Repeated stimulation sometimes produced similar differences. Finally, the two responses were not linearly related as a function of stimulus intensity or flow rate. However, for reasons discussed, it is difficult to conclude that these discrepancies necessarily reflect unfavorably upon the reliability of the mucosal potential as the criterion measure of peripheral olfactory activity. Nevertheless, the mucosal potential should not be accepted unequivocally as such a criterion measure until it is more thoroughly understood.
