Abstract
Amplitude variations of local EOG [electroolfacto grams] collected from 121 points of the olfactory epithelium of the frog were recorded in response to 20 olfactory stimuli. There was a strong correlation between the amplitude of the local EOG and the density of the olfactory receptors in the corresponding recording area. A population of about 400-700 receptors contained all kinds of olfactory sensibility with variable proportions according to the recording point. At the receptor level spreading over about 1/6 of the olfactory surface, an anterio-posterior differentiation appeared. The topographical distribution of the local EOG elicited by the 20 stimuli significantly differed between animals.
