In the African giant snail, Achatina fulica Férussac, the ionic mechanisms underlying slow
depolarization of a heart excitatory neurone, PON, induced by the activity of two cerebral …

Electron microscopy of the cardiac ganglion from normal and bilaterally vagotomized turtles
revealed the occurrence of reciprocal synapses between the postganglionic cholinergic …

Involvement of neuropeptides in the regulation of cardiac activity in a prosobranch mollusc,
Rapana thomasiana, was studied physiologically as well as immunohistochemically. A catch …

9 cardioregulating neurones belonging to 5 different functional groups were studied in
visceral and right parietal ganglia of the Giant African snail Achatina fulica. The neuronal …

Objectives of the Study: 1. To map the cholinergic and adrenergic nerve fibers in frog atrial
whole mounts. 2. To evaluate the fluorescence intensities of cholinergic and adrenergic …

Data on new, previously unidentified nerve cells of the snail Helix pomatia are presented in
this paper. The identified neurons described may serve as a convenient model for the …

The effects of putative neurotransmitters and modulators on the atrium preparation of the
gastropod Achatina fulica were observed in order to investigate the regulatory mechanisms …

The cardioexcitatory neuropeptide FMRFamide was first identified and characterised by
Price and Greenberg in the mollusc Macrocallista nirnbosa. Since then the peptide has been …

An undecapeptide which potentiates the beat of the ventricle in the African giant snail,
Achatina fulica Férussac, was purified from the atria of the snail. Its primary structure was …

1. The main part of the cardiac ganglion consists of three types of axons. 2. 2. Two of these
types can be distinguished by electron-dense granules ranging between 700–1000 and …
