Lymnaea stagnalis
- Pharmacological effects of cannabinoids on learning and memory in Lymnaea
Highlighted Article: Putative cannabinoid receptors are present in a mollusc and mediate stressful stimuli that alter learning and memory formation.
- The activity of isolated neurons and the modulatory state of an isolated nervous system represent a recent behavioural state
Summary: In the pond snail Lymnaea stagnalis, the behavioural state can produce long-term changes in individual neurons that persist even after neuron isolation from the nervous system as well as alterations in the neurochemical microenvironment of the central ganglia.
- Sequential exposure to a combination of stressors blocks memory reconsolidation in Lymnaea
Summary: Reconsolidation occurs after a memory has been activated. We show here that a combination of stressors can block this process.
