[Bilateral projection of the olfactory mucosa in the frog].
Bulbar potentials wer bilaterally recorded in the frog following electrical stimulation of one olfactory nerve bundle. The general features of the contralateral evoked response were very similar to those of ipsilateral ones. The contralateral response was shown to be produced in situ, not being electronically transmitted from the bulb on the stimulated side. Its response disappeared after section of the olfactory interbulbar adhesion but was not affected by sectioning through either the anterior or the habenular commissure. It was concluded that messages from the neuroreceptors belonging to either the ventral or the dorsal olfactory mucosa on one side, reach both olfactory bulbs.
