Predator 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 کاملPredator detection enables juvenile Lymnaea to form long-term memory.
Learning and memory provide the flexibility an organism requires to respond to changing social and ecological conditions. Juvenile Lymnaea have previously been shown to have a diminished capacity to form long-term memory (LTM) following operant conditioning of aerial respiratory behavior. Juvenile Lymnaea, however, can form LTM following classical conditioning of appetitive behaviors. Here, we ...
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...
متن کاملSerotonergic Modulation of Patterned Motor Output in Lymnaea Stagnalis
Rhythmic feeding motor output from the buccal ganglia of Lymnaea stagnalis was evoked by tonic depolarization of the pattern-initiating interneurone SO in the isolated central nervous system. Perfusion with 10~moll~' serotonin (5-HT) led to a reduction in frequency of the SO-driven rhythm, and in some cases rhythmic activity was completely blocked. The frequency reduction was predominantly due ...
متن کاملModelling a Respiratory Central Pattern Generator Neuron in Lymnaea Stagnalis
Lymnaea stagnalis, often termed the great pond snail, is characterized in part by its ability to take in oxygen both cutaneously and aerially (via its rudimentary lung). The central nervous system of the Lymnaea is composed of a relatively small number of large, identifiable neurons. In 1990, Syed et al. [1] established that respiratory rhythmogenesis in the Lymnaea is controlled by a 3-neuron ...
