Abstract:
We stimulated the olfactory mucosa electrically and elicited evoked potentials in rabbits. A bipolar stimulating electrode was placed on the olfactory region of the nasal mucosa via an anterior naris non-invasively. Evoked potentials were detected from the surface of a head. In most instances they were composed of triphasic negative-positive-negative peaks, the latencies of these peaks were about 25, 40, and 65 ms, respectively. This peak complex seemed to originate in the olfactory bulb. This method is non-invasive and is applicable to studying the olfactory system in animals and also in humans.
