title: Attacking sleep from a new angle: contributions from zebrafish.
abstract: Sleep consumes a third of our lifespan, but we are far from understanding how it is initiated, maintained and terminated, or what purposes it serves. To address these questions, alternative model systems have recently been recruited. The diurnal zebrafish holds the promise of bridging the gap between simple invertebrate systems, which show little neuroanatomical conservation with mammals, and well-established, but complex and nocturnal, murine systems. Zebrafish larvae can be monitored in a high-throughput fashion, pharmacologically tested by adding compounds into the water, genetically screened using transient transgenesis, and optogenetically manipulated in a non-invasive manner. Here we discuss work that has established the zebrafish as a powerful system for the study of sleep, as well as novel insights gained by exploiting its particular advantages.
