SNAKE LOGIC David Holtzman, an assistant professor of brain and cognitive science at the University of Rochester, has loved snakes since childhood. But in college, when he wanted to investigate how snake brains develop, he found that serpents weren't exactly model organisms. "I wanted to devise a task that could show that snakes can learn as well as rodents--if you ask them to do the right thing," he recalls. Now Holtzman and his colleagues are doing just that (D.A.
