In just 50 milliseconds rats can not only identify an odor, but can tell in which nostril an odor is stronger and then head for it.
"Rats are smart and great at odor-related tasks, so they were a good system to get at the question in detail," said olfactory researcher Upinder Bhalla of the National Center for Biological Sciences in Bangalore, India.
