[The electrical activity of olfactory bulb II in the frog].

The paper refers to the extracellular field potentials of frog's olfactory secondary bulb elicited by means of electrical stimulation of vomero-nasal nerve. These potentials become evident as compound waveform both in situ and in vitro and their components are easily reliable to the activity of intrinsic neuronal circuitry of the bulb. The similarity of the field potentials in the olfactory primary and secondary bulbs is discussed.
