The ability to correlate the behaviour of neurones in intact ganglia with events in isolation as has been shown in the leech (Ready & Nicholls, 1979; Fuchs, Nicholls & Ready, 1981), may provide insight into the intrinsic properties of individual neurones. The culture of molluscan neurones is relatively new and the exact procedures for the control of environmental conditions necessary for obtain...
The suitability of neurons of the freshwater snail Lymnaea stagnalis as a test system for the neurotoxic side effects of antitumour Vinca alkaloids has been investigated, by studying the process of paracrystal induction by Vinca antitumour agents. Three Vinca alkaloids have been compared: the natural vinblastine and vincristine and the semisynthetic vindesine. They appear to induce two types of...
We present here a spatial and temporal population genetic survey of a common freshwater snail, also a predominantly selfing species, Lymnaea truncatula. The rate of genetic diversity loss was quantified by estimating the effective size (Ne) of the snail populations, using two different methods. A temporal survey allowed estimation of a variance effective size of the populations, and a spatial s...
