... of aerial respiration, where they received a single 0.5 h training session followed by a long-term memory (LTM) test 24 h later. Immediately after the memory test, snails were killed and the expression levels of key genes for neuroplasticity, energy balance and stress response were measured in the central...

... granulata can be trained to associate a specific environment with an appetitive reward in a conditioned place preference task. After a single training trial, when the crabs were presented with a food pellet in the target quadrant of the training arena, they were able to form a long-term memory related...

... memory was retained for at least 48 h, although a single bout of training was also enough to form a long-term memory. Cooling animals at 4°C or injection of cycloheximide immediately after training altered the formation of long-term memory, but had no effect on short-term memory formation. Administration...

.... Previously, two combinations of stressors were purported to prevent long-term memory (LTM) formation in ‘smart’ Lymnaea and this inability to form LTM was considered to be a cost of being smart. Here, we show that is not the case. The specific combinations of stressors used here cause emotional memory...

... formation. This effect of WIN 55 injection persisted for at least 4 days following its injection. A similar obstruction of learning and memory occurred when a severe traumatic stimulus was delivered to L. stagnalis . In contrast, injection of a mammalian CBr antagonist AM 251 enhanced long-term memory...

...Tamila Shymansky; Amy Protheroe; Emily Hughes; Cayley Swinton; Erin Swinton; Kai S. Lukowiak; Iain Phillips; Ken Lukowiak ABSTRACT Previously, it was concluded that the nervous systems of juvenile snails were not capable of mediating long-term memory (LTM). However, exposure and training of those...

.... One such stressor is heat. Previously, we found that following a 1 h heat shock, long-term memory (LTM) formation was enhanced. We also had shown that the heat stressor activates at least two heat shock proteins (HSPs): HSP40 and HSP70. Here, we tested two hypotheses: (1) the production of HSPs...

...Bogdan Knezevic; Yoshimasa Komatsuzaki; Emily de Freitas; Ken Lukowiak ABSTRACT The ability to remember is influenced by environmental and lifestyle factors, such as stress and diet. A flavanol contained in chocolate, epicatechin (Epi), has been shown to enhance long-term memory (LTM) formation...

...Christina Scholl; Natalie Kübert; Thomas S. Muenz; Wolfgang Rössler ABSTRACT Honeybees are able to solve complex learning tasks and memorize learned information for long time periods. The molecular mechanisms mediating long-term memory (LTM) in the honeybee Apis mellifera are, to a large part...

...Shawn Xavier Dodd; Ken Lukowiak ABSTRACT Stress alters the formation of long-term memory (LTM) in Lymnaea . When snails are exposed to more than one stressor, however, how the memory is altered becomes complicated. Here, we investigated how multiple stressors applied in a specific pattern affect...

We have shown that several different manipulations, including pre-training exposure to serotonin (5-HT) or methamphetamine, submersion of snails after training to prevent memory interference, and exposure to effluent from predatory...

Together, these results show that learning is a crucial component in odour responses in A. aegypti , and provide the first evidence for the functional role of different memory traces...

... here on how environmentally relevant stressors alter learning, memory and forgetting in the pond snail, Lymnaea stagnalis . Operant conditioning of aerial respiration causes associative learning that may lead to long-term memory (LTM) formation. However, individual ecologically relevant stressors...

We found that bees exposed to imidacloprid, coumaphos, or a combination of these compounds, were less likely to express conditioned proboscis...

... here (Dutch strain), a single 0.5 h training session (TS) results in intermediate-term (3 h) but not long-term memory (LTM). Applying the thermal stressor during training caused memory enhancement (i.e. LTM lasting 24 h). However, the breathing rate also increased in warm water, which might explain...
