Summary

Single fiber recordings have been made from the lateral olfactory tract of the fish and the effects of stimulation of the olfactory mucosa studied. The following results were obtained:

  1. 1.

    A fiber exhibits different patterns of activity when different odors are employed (temporal coding).

  2. 2.

    Different fibers respond to the same odor in different way (spatial coding).

  3. 3.

    The response to the stimulus depends not only on the nature of the odor, but also upon its concentration, turbulence of the water-stream acting on the mucosa, and the spontaneous background activity of the fiber. However, the effect of an odor was consistently reproducable provided that the other parameters did not change.

  4. 4.

    Many fibers discharge in rhythmic bursts, spontaneously, or on stimulation with an odor. This rhythmic activity persists after dissection of the central end of the olfactory tract.

  5. 5.

    Most fibers exhibit adaptation following continuous stimulation with the same odor.

  6. 6.

    The position of receptors belonging to the fiber being recorded, can be determined by mechanical stimulation of discrete areas of the olfactory mucosa. Stimulation receptors, others than those connected to the fiber, results in lateral inhibition.

During mechanical stimulation of the mucosa, olfactory adaptation to an odor is suppressed. This may suggest a mechanism corresponding to “sniffling” of mamals helping the fish to localize the source of food.
