“What we discovered was that this brain area wasn't exclusively used for sensing magnetic fields, but instead it's being used to perhaps see at night.”
“It just pops out at you… There's just no way you can ignore it. When an animal performs a particular behavior the areas of the brain that are responsible for performing that behavior… induce the synthesis of certain genes in the brain. You can actually use that induction of synthesis of genes to identify the area that was active in that particular behavior.”
