Nearly everything we do depends on our brains. The same is true for other animals, which is not so surprising, because we share an ancestor with them (yes, evolution happened!). This shared ancestry means that the brains of all animals have much in common, so we can study any one of them to learn about our own. My lab attempts to reveal how vertebrate brains work by studying an animal, transparent young zebrafish, in which we can literally watch the brain as it is built and as it works. Have a look at what we do here.
