Just One Gene Is Necessary For Mice To Avoid Predators: Discovery May Improve Understanding Of How Neural Circuits Contribute To Behavior

When a mouse smells a cat, it instinctively avoids the feline or risks becoming dinner. How? A Northwestern University study involving olfactory receptors, which underlie the sense of smell, provides evidence that a single gene is necessary for the behavior. A research team led by neurobiologist Thomas Bozza has shown that removing one olfactory receptor from mice can have a profound effect on their behavior. The gene, called TAAR4, encodes a receptor that responds to a chemical that is enriched in the urine of carnivores... via Health News from Medical News Today Read More Here..
