Coupled neuronal oscillators in the snail Lymnaea stagnalis: endogenous cellular properties and network interactions.

Molecular detection of the infection with Fasciola hepatica in field-collected snails of Galba truncatula and Lymnaea stagnalis from West Azarbaijan, Iran

The liver fluke, Fasciola hepatica, is considered as the most common cause of fasciolosis in both domestic livestock and human. This study was carried out to detect the prevalence of the larval stages of F. hepatica in the snails Galba truncatula and Lymnaea stagnalis in West Azarbaijan, Iran. Snail collection was performed through searching 28 freshwater habitats from May to December 2010. Fol...

Cloning, characterization, and expression of a G-protein-coupled receptor from Lymnaea stagnalis and identification of a leucokinin-like peptide, PSFHSWSamide, as its endogenous ligand.

Neuropeptides are known to be important signaling molecules in several neural systems of the pond snail Lymnaea stagnalis. Although the functions of these peptides have been studied in many neurons, the nature of the postsynaptic signal transduction is mainly unknown. The cloning and characterization of neuropeptide receptors in Lymnaea thus would be very valuable in further elucidating peptide...

Short Communication Neuronal Feedback in Egg-laying Behaviour of the Pond Snail Lymnaea Stagnalis

Inhibition of the respiratory pattern-generating neurons by an identified whole-body withdrawal interneuron of Lymnaea stagnalis

Respiration and the whole-body withdrawal are two incompatible behaviors in the freshwater snail Lymnaea stagnalis. Whole-body withdrawal behavior is believed to be higher on the behavioral hierarchy than respiratory behavior. A central pattern generator (CPG) underlies respiratory behavior; whole-body withdrawal is mediated by a network of electrically coupled neurons. In this study, we provid...

A neuronal network from the mollusc Lymnaea stagnalis.

The morphology, electrophysiology, and synaptic inputs of a ventrally located neuronal network from the CNS of the pond snail Lymnaea stagnalis was investigated. Three large, previously identified neurons [55] known as right parietal ventral one, two, and three (RPV1,2,&3) were found to be electrically coupled to one another. Coupling between either RPV1&2 or RPV1&3 was weak while coupling betw...
