    Notes: Abstract The intra-cardiac nervous system of the decapod heart is composed of large and small ganglionic cells (LGCs and SGCs) and axons of extrinsic cardio-acceleratory and-inhibitory neurons (CAs and CIs). Candidate neurotransmitters for the neurons have been determined by pharmacological, cytochemical and immunocytochemical tests. SGCs may be cholinergic, LGCs and CAs are probably dopaminergic, and CIs are GABAergic. Serotonin and octopamine were cardio-excitatory neuromodulators of the heart. Proctolin, crustacean cardio-active peptide (CCAP), red pigment concentrating hormone (RPCH), and FMRFamide also had modulatory actions on the heart. Proctolin was the most potent peptide, which acted primary on the cardiac ganglion. Insect adipokinetic hormones had little effect on the heart.

    Dopaminergic acceleration and GABAergic inhibition in extrinsic neural control of the hermit crab heart (1994)

    Notes: Abstract The acceleratory and inhibitory cardio-regulatory nerves of hermit crabs (Aniculus aniculus, Dardanus crassimanus) were studied using histochemical, immunocytochemical and pharmacological tests. Glyoxylic acid-induced fluorescence was observed in two of three axons of the dorsal cardiac nerve. One axon of the nerve showed gamma-aminobutyric acid-like immunoreactivity. Effects of stimulation of cardio-acceleratory axons were blocked by the dopaminergic antagonists, haloperidol and chlorpromazine, but not by cholinergic, adrenergic or serotonergic blockers, suggesting that dopamine is the primary potential candidate for the neurotransmitter of cardio-accelerator neurons. Picrotoxin antagonized inhibition of the cardiac ganglion induced by gammaam-inobutyric acid and by cardio-inhibitory axons. Both small and large ganglionic cells may receive dopaminergic and GABAergic extrinsic neural control.

    Identification of an abdominal ganglion neuron antagonizing L7-driven gill contraction in Aplysia (1999)

    Notes: Abstract Gill motor neuron L7-induced longitudinal shortening of the gill in Aplysia kurodai and A. juliana was suppressed when extracellular stimuli were applied to a restricted dorsal central region of the abdominal ganglion. We found a neuron there which antagonized the L7-driven contraction. Since the contraction was suppressed when the identified neuron was activated simultaneously with L7, we refer to the newly found neuron as “Anti-L7”. Anti-L7 did not change the L7 impulse generation in the abdominal ganglion. No direct synaptic connection from L7 to Anti-L7 was detected. A fluorescent dye injected into the soma of Anti-L7 revealed that the neuron sent axonal branches to the branchial nerve. These results may show that Anti-L7 antagonizes L7 at the periphery inside the gill, rather than in the abdominal ganglion. EJPs induced by L7 were unaffected by Anti-L7. Activation of Anti-L7 alone did not induce any change in tone or membrane potential of the gill musculature. The suppressive effect of Anti-L7 lasts many seconds after the cessation of a train of Anti-L7 impulses. The results may suggest that the suppression is mediated through an inhibitory neuromodulatory mechanism without inhibition of L7 itself.

    Neural mechanisms governing distribution of cardiac output in an isopod crustacean, Bathynomus doederleini: reflexes controlling the cardioarterial valves (1995)

    Notes: Abstract In Bathynomus doederleini all of the cardioarterial valves located at the origin of the lateral arteries are dilated by impulses of lateral cardiac nerves. Tactile stimuli applied to sensillar setae depress impulse activities of the 1st and 5th lateral cardiac nerves. The 1st lateral cardiac nerve controls the valve of the lateral artery which runs to the walking-legs and viscera. The 5th lateral cardiac nerve controls the valve of the lateral artery which runs to the swimmeret muscles. The response indicates that tactile receptor reflexes bring about decreased haemolymph flow to the organs. Augmented swimmeret movements were always accompanied by an increased firing rate in the 5th lateral cardiac nerve. Artificial full protraction of swimmerets simultaneously induced excitation of the 5th lateral cardiac nerve and inhibition of the 1st lateral cardiac nerve. The excitation corresponds to an increase in haemolymph flow to the swimmerets, and the inhibition a decrease in haemolymph flow to walking-legs and viscera. Three kinds of mechanoproprioceptors which were activated by swimmeret movements were found. Two of the mechanoproprioceptors are located at the base of the basipodite. The other mechanoproprioceptor supplies processes to a nerve to the retractor muscles. Activation of three kinds of mechanoproprioceptors, induced by artificial swimmeret protraction, triggered lateral cardiac nerve reflex responses.

    Afferent pathways in the innervation of the ventricle of a prosobranch gastropodBusycon canaliculatum (1975)

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