Description: A key feature of sleep is reduced responsiveness to the environment, which puts animals in a particularly vulnerable state; yet, sleep has been conserved throughout evolution, indicating that it fulfills a vital purpose. A core function of sleep across species has not been identified, but substantial advances in sleep research have been made in recent years using the genetically tractable model organism, Drosophila melanogaster. While a standard approach in sleep research is to study the effects of short-term sleep deprivation on an animal, tools are now available to genetically manipulate sleep amount in the fruit fly. In particular, a number of short-sleeping Drosophila mutants have been identified that model the long-term sleep restriction that is widespread in modern society. This thesis describes a body of work in which short-sleeping Drosophila mutants, as well as other genetic and pharmacological tools, were used to shed light on the function and regulation of sleep.
