Observations on the Embryonic Development of Freshwater Pulmonate Snail Lymnaea Acuminata (lamarck, 1822) (gastropoda: Mollusca)
Molluscs have played important role in strengthening our knowledge of fundamental processes in developmental biology, with the common pond snail Lymnaea stagnalis contributing greatly to this body of literature for nearly a century (Gatenby, 1919; Sturtevant, 1923; Canton and Sloof, 1977). The morphological, morphometric and behavioral aspects of development of L. stagnalis have been well docum...
متن کاملPredator detection in Lymnaea stagnalis.
Laboratory-reared Lymnaea are capable of detecting and responding to the scent of a crayfish predator. The present investigation is a first attempt to characterize multiple stress-related behavioural responses resulting from predator detection and to depict the neurophysiological correlates of one of these illustrated behaviours. Snails respond to crayfish effluent (CE) by increasing the follow...
متن کاملBehavioural and Neural Correlates of Operant Conditioning in Lymnaea Stagnalis: Role of Previous Experience during Development
The freshwater mollusc Lymnaea stagnalis was utilized in this study to further the understanding of how network properties change as a result of associative learning, and to determine whether or not this plasticity is dependent on previous experience during development. The respiratory and neural correlates of operant conditioning were first determined in normally reared Lymnaea. The same proce...
متن کاملChemosensitivity of the osphradium of the pond snail Lymnaea stagnalis
The osphradium of the pond snail Lymnaea stagnalis was studied to determine the stimuli to which this organ responds. The following stimuli were tested: hypoxia, hypercapnia, a mixture of amino acids, a mixture of citralva and amyl acetate and a mixture of lyral, lilial and ethylvanillin. The mean nerve activity consistently increased with elevated PCO2, whereas hypoxia produced variable effect...
متن کاملOperant conditioning of aerial respiratory behaviour in Lymnaea stagnalis
In this study, we operantly conditioned the aerial respiratory behaviour of the freshwater snail Lymnaea stagnalis. Aerial respiration in Lymnaea stagnalis is accomplished by the spontaneous opening and closing of its respiratory orifice, the pneumostome, at the water surface. Weak tactile stimulation of the pneumostome area, when the pneumostome is open, evoked only the pneumostome closure res...
