Snail Offers Clue to How Anesthetics Work

While scientists thought the brain's potassium channel played a key role in regards to anesthetics, the theory couldn't be tested until Franks' team cloned a giant pond snail's potassium channel and created chimeric channels to identify a specific amino acid.

By studying that amino acid, the group was able to identify how an anesthetic binds to the potassium channel and limits the amount of neural impulses to the body's neurons.


I'm not sure what they mean by 'Giant Pond Snail', but I figured it has a good chance of being an Applesnail if its that big, maybe not. Full story at above link.

Very interesting!

"Giant pond snail" probably refers to Lymnaea stagnalis, which has that common name in various parts of Europe.

That could be - I forgot about those. Too bad they didn't mention the species.
