Adult crayfish have a neurogenic heart which is modulated via inputs from the central nervous system and neurohormones, which act on the cardiac ganglion or directly on the myocardium. This study investigates the ontogeny of cardiac regulation by exploring the temporal sequence of cardiac sensitivity to injections of cardioactive neurohormones (proctolin, serotonin and octopamine) and the neurotransmitter γ-aminobutyric acid. The cardiac response (Δ in heart rate, stroke volume, or in cardiac… CONTINUE READING
