Most sleep does not serve a vital function: Evidence from Drosophila melanogaster

摘要: Sleep appears to be a universally conserved phenomenon among the animal kingdom, but whether this notable evolutionary conservation underlies basic vital function is still an open question. Using machine learning-based video-tracking technology, we conducted detailed high-throughput analysis of sleep in fruit fly Drosophila melanogaster, coupled with lifelong chronic and specific restriction. Our results show that some wild-type flies are virtually sleepless baseline conditions complete, forced restriction not necessarily lethal treatment D. melanogaster. We also circadian drive, homeostatic regulation, main contributor pressure flies. These offer new perspective on biological role and, potentially, other species.
