Summary

  1. 1.

    Stretch applied to the ventricle, or contraction of the heart, sets up afferent activity (presumably of a sensory nature), in the cardiac nerve ofBusycon canaliculatum. Such afferent activity, elicited by either mechanical or electrical stimuli, can be traced through the pseudoganglion, the cardiac nerve, and the visceral ganglia to the parietal-visceral connectives.

  2. 2.

    In response to the induced afferent activity, efferent activity appears and can be recorded from a teased-out intracardiac branch of the cardiac nerve.

  3. 3.

    Section of the cardiac nerve distal to the visceral ganglia may lead to an increase in amplitude of compound peaks in the extra- or intraventricular cardiac nerve.

  4. 4.

    Electrical activity ceases in the intraventricular branches of the cardiac nerve, after severing the cardiac nerve distal to the pseudoganglion.

  5. 5.

    The pseudoganglion is possibly a reflex center for the intraventricular branches of the cardiac nerve, but there is an inhibitory central influence on the reflexes. The inhibitory influence is probably exerted by the visceral ganglia.
