Reconsolidation and memory infidelity in Lymnaea.
Lymnaea stagnalis were operantly conditioned to not perform aerial respiratory behaviour in a specific context (i.e. context-1). The memory for this learned response was reactivated 3 days later in context-1. During the 1 h reconsolidation period following memory reactivation, randomly picked snails were either maintained in context-1 or exposed to a new context (i.e. context-2). One hour later...
متن کاملAssociative learning and memory in Lymnaea stagnalis: how well do they remember?
The search for 'the how and the where' of memory formation in the brain, the engram, is still one of the unattained 'Holy Grails' of neuroscience. Over the years, various paths have been trodden in attempts to attain this goal, and while tantalizing glimpses appear now and then on the scientific horizon, the Grail still has not been grasped. One of the paths that investigators have walked is th...
متن کاملLearning and memory in Lymnaea are negatively altered by acute low-level concentrations of hydrogen sulphide.
Hydrogen sulphide (H(2)S) is a common industrial pollutant as well as an endogenous neural transmitter/neural modulator. Experiments were performed on the pond snail Lymnaea stagnalis to determine the acute effects of low-level exposure to H(2)S (50-100 micromol l(-1)) on aerial respiratory behaviour, associative learning, and its subsequent consolidation into long-term memory (LTM). A 3-neuron...
متن کاملRepeated cocaine effects on learning, memory and extinction in the pond snail Lymnaea stagnalis.
The persistence of drug addiction suggests that drugs of abuse enhance learning and/or impair extinction of the drug memory. We studied the effects of repeated cocaine on learning, memory and reinstatement in the pond snail, Lymnaea stagnalis. Respiratory behavior can be operantly conditioned and extinguished in Lymnaea, and this behavior is dependent on a critical dopamine neuron. We tested th...
متن کاملComparing memory-forming capabilities between laboratory-reared and wild Lymnaea: learning in the wild, a heritable component of snail memory.
We set out to determine whether the ability to form long-term memory (LTM) is influenced by laboratory rearing. We investigated the ability of four populations of Lymnaea stagnalis to form LTM following operant conditioning both in the freely behaving animal and at the electrophysiological level in a neuron, RPeD1, which is a necessary site for LTM. We hypothesized that laboratory rearing resul...
