在刺猬和兔子的嗅球中，Adrian发现嗅觉刺激诱发的电位波呈电位振荡的形式。据推测，波是由灯泡的树突区域中的同步活动开发的。后来，he 3在家兔嗅上皮中记录到了类似的电位，并发现其电位模式具有嗅球中出现的所有特征。在实验中，Adrian 3没有同时记录上皮和嗅球中的电位;但从相似性出发，他推测嗅球中产生电位振荡的机制起源于嗅上皮。在青蛙的嗅上皮中，奥托森发现，有节奏的波有时会出现在由气味刺激产生的慢电位的波峰上。他假定它们与阿德里安发现的潜在振荡相同1 -3。
IN the olfactory bulb of the hedgehog and the rabbit, Adrian1,2 found that the potential waves evoked by olfactory stimulation take shapes of potential oscillation. It was presumed that the waves were developed by synchronized activity in the dendritic region of the bulb. Later, he3 recorded the similar potential in the olfactory epithelium of the rabbit, and found that the potential pattern in the epithelium has all the features of that appearing in the bulb. In the experiment, Adrian3 did not record the potentials in the epithelium and the bulb simultaneously; but from the similarity he presumed that the mechanism which produces the potential oscillation in the bulb originates in the olfactory epithelium. In the olfactory epithelium of the frog, Ottoson4 found that rhythmic waves sometimes superimpose on the crest of the slow potentials produced by odour stimulation. He presumed that they are identical to the potential oscillations found by Adrian1–3.
