【Significance】
Suppression of monoamine content is a key factor for conditioned taste aversion in snails

Pond snails learn conditioned taste aversion (CTA) and consolidate it into long-term memory. An in-bred Dutch strain has the superior CTA memory formation compared to the Canadian TC1 strain and the F1 cross snails. We hypothesize that this is due to differences in the monoamine content between the three populations. We measured serotonin, dopamine, octopamine, their precursors and catabolites in the brain. We found that the Dutch strain had the lowest overall monoamine content. Thus, suppression of monoamine content in the brain may be a key factor in conditioned taste aversion in snails.
