Eve Marder: freeing knowledge, crashing neurons

None of us would get on a plane that had its parts changed in mid-air, says Eve Marder, who has spent her career probing a very specific cluster of crustacean nerve cells. Yet we are all walking around undergoing a constant turnover of cellular parts, and so are the lobsters and crabs Marder studies.
