oxymoron Talk: A snail on speed. No, the researchers were not trying to make gastropods glide faster, they have tried to improve their memories. When the great snail pond ( Lymnaea stagnalis ) wades through the water poor in oxygen, it extends a special tube to the surface breathing. A team of researchers trained snails not to repeatedly pushing their breathing tubes when the snails have tried to expand. Two days later, the team again placed the snails in the water poor in oxygen. Snails formed in normal water had already forgotten their training, and they extended their breathing tubes twice as often as snails trained in meth-laced water, the researchers report tomorrow The Journal of Experimental Biology . The results suggest that methamphetamine improves memory, something that has already been observed in creatures with large complex brains like rats and humans. But since the snails store their memories in a single network, three neurons, the team hopes that the study of the effect of methamphetamine in these gastropods will identify how the drug expansion memory powers working.
