            The terminal nerve: a new chemosensory system in vertebrates?

            Ganglion cells of the terminal nerve in goldfish are located in the olfactory nerve and bulb and send peripheral processes into the olfactory epithelium and central processes to the supracommissural nuclei of the telencephalon as well as to the retina. Correlations between terminal nerve projections and neurobehavioral studies suggest that the terminal nerve mediates responses to sex pheromones.

              Effects of olfactory tract lesions on sexual and feeding behavior in the goldfish.

              The paired olfactory tracts (OTs) of goldfish each have a lateral (LOT) and medial (MOT) olfactory tract, the latter with medial (mMOT) and lateral (lMOT) subdivisions. Bilateral OT section (OTX) reduced, while unilateral OT section (UNI) did not impair, male sexual behavior and feeding responses to a complex food odor; in contrast, female sexual behavior, induced in both sexes by prostaglandin treatment, was little affected by OTX. Experiments in which control fish were given UNI and treatment groups received UNI plus selective section of the remaining OT assessed the role of the OT subdivisions in the two olfactory-influenced behaviors (male sexual behavior and feeding). LOT section did not affect courtship, while MOT section reduced courtship to the low levels seen in OTX males; within the MOT, the mMOT may be more important than the lMOT for courtship expression. In contrast to male sexual behavior, feeding responses were less affected by MOT than LOT section. With respect to male sexual behavior, these findings demonstrate differential functions for the anatomically distinct subdivisions of the goldfish olfactory tracts, possibly related to their distinct terminal fields within the telencephalon.
