Biologists identify genes regulating sleeping and feeding

In the quest to better understand how the brain chooses between competing behaviors necessary for survival, scientists at the University of Massachusetts Medical School and New York University have isolated two genes in the fruit fly Drosophila that work together to mediate the need to sleep and the need to eat. The study, which appears in the online version of Current Biology, offers insights that may be used to understand sleep-and metabolism-related disorders in humans.
