The toxicity and physiological effects of copper on the freshwater pulmonate snail, Lymnaea stagnalis.

Several recent studies have demonstrated that the freshwater pulmonate snail Lymnaea stagnalis is extremely sensitive to metals (Co, Ni, Pb) in chronic exposures. The objective of the current study was to evaluate the acute and chronic sensitivity of L. stagnalis to Cu and investigate the underlying mechanism(s) of toxic action. A 96-h LC50 of 31μg L(-1) Cu was estimated indicating L. stagnalis...

Equilibrium and kinetic studies of oxygen binding to the haemocyanin from the freshwater snail Lymnaea stagnalis.

The binding of oxygen by the haemocyanin of the gastropod Lymnaea stagnalis was studied by equilibrium and kinetic methods. The studies were performed under conditions in which the haemocyanin molecule was in the native state. Over the pH range 6.8-7.6, in the presence of 10mM-CaCl2 the haemocyanin bound O2 cooperatively. Over this pH range the haemocyanin molecule displayed a normal Bohr effec...

In vitro appetitive classical conditioning of the feeding response in the pond snail Lymnaea stagnalis.

In vitro appetitive classical conditioning of the feeding response in the pond snail Lymnaea stagnalis. J. Neurophysiol. 78: 2351-2362, 1997. An in vitro preparation was developed that allowed electrophysiological analysis of appetitive conditioning of feeding in the model molluscan system, Lymnaea. The network generating the feeding motor program (fictive feeding) is well characterized at the ...

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

The role of endogenous cellular properties and network interactions due to electrotonic coupling were investigated in two bilateral populations of 2-7 peripheral neurones ('Peripheral Bursters') in the snail Lymnaea stagnalis. 1. These cells are endogenously capable of bursting. Their burst frequency does not depend on the level of steady membrane polarization. Short hyperpolarizing current pul...

Neurophysiological correlates of unconditioned and conditioned feeding behavior in the pond snail Lymnaea stagnalis.

We used a behavioral appetitive learning paradigm followed by electrophysiological analysis to investigate the neuronal expression of appetitive conditioning in Lymnaea. We first established the levels of unconditioned and conditioned feeding responses in intact animals. We then demonstrated that neuronal correlates of both unconditioned responses to touch and food and a conditioned response to...
