Neuroscience Social Experience and the Need to Sleep
Science, AAAS, Cambridge CB2 1LQ, UK
Sleep is widely observed in the animal kingdom and yet we still dont know why it is beneficial. Studying Drosophila, Ganguly-Fitzgerald et al. developed a strategy for elucidating the mechanisms underlying the need to sleep. They observed that a rich social experience, versus an impoverished one, increased the duration of sleep, which in turn was promoted by processes that underlie learning and memory, such as dopamine and cyclic adenosine monophosphate signaling pathways. Mutations in 17 genes were found to disrupt experience-dependent changes in sleep.
