title: [Regulation of signals in the chemosensory systems of fish].
abstract: Irritation of olfactory lining and adjacent skin with chemical solutions elicited electrical signals not only in the olfactory system, but in the fibers of nn. trigeminus and facialis of the fish. Latency is shorter in the trigeminal system than in the olfactory one. Electrical stimulation of the nn. trigeminus, facialis, of the contralateral olfactory tracts modulates the signals coming to the olfactory bulb and projecting from it as well as inhibits the response to adeguate olfactory stimulation. Stimulation of afferents of the nn. trigeminus and facialis modulates signals in their efferent fibers both contra- and ipsilaterally.
