Biologists turned snails into tweakers to learn more about how crystal meth seems to improve memory in humans. According to the Washington State University and University of Calgary researchers, memories formed while on methamphetamine may be more durable. (They ran another snail study in 2006 using cocaine instead of meth.) Their work could someday provide a deeper understanding of addiction. From EurekAlert! (images from Wikimedia Commons):
...The team wondered whether meth could improve the snails' memories. First they immersed the snails in meth-laced pond water, then they moved them into regular de-oxygented pond water and gave them a training session that the snails should only recall for a few hours. In theory the snails should have forgotten their training 24 hours later, but would the meth improve the snails' memories so they remembered to keep their pneomostomes closed a day later? It did. A dose of meth prior to training had improved the snails' memories, allowing them to recall a lesson that they should have already forgotten. And when the team tested whether they could mask the meth memory with another memory, they found that the meth memory was much stronger and harder to mask.
