TL;DR
Sleep is universal, tightly regulated, and cannot be deprived without deleterious consequences, which suggests that searching for a core function of sleep, particularly at the cellular level, is still a worthwhile exercise.
Abstract
No current hypothesis can explain why animals need to sleep. Yet, sleep is universal, tightly regulated, and cannot be deprived without deleterious consequences. This suggests that searching for a core function of sleep, particularly at the cellular level, is still a worthwhile exercise.

The EEG appeared relatively desynchronized and symmetrical between the two hemispheres when the animal was awake during recovery from pentothal-halothane anesthesia as well as during waking periods when one or both of the animal’s eyes were covered by an opaque rubber suction cup.
Sleep Medicine ReviewsThe trivial function of sleep
81 Citations2007Rubén V. Rial, M.C. Nicolau +9 more
It is argued that the function of sleep could be trivial for mammals and birds because sleep does not provide additional advantages over simple rest, and it is proposed that few, if any, phenotypic selectable traits do exist in sleep.
Methods in enzymology on CD-ROM/Methods in enzymologyDrosophila melanogaster: An Insect Model for Fundamental Studies of Sleep
81 Citations2005Karen S. Ho, Amita Sehgal
The methods currently used to identify and characterize the Drosophila sleep state are reviewed and the powerful techniques afforded by this organism are likely to unveil deep insights into the function(s) and regulatory mechanisms of sleep.
BMC NeuroscienceHomeostatic regulation of sleep in the white-crowned sparrow (Zonotrichia leucophrys gambelii)
75 Citations2008Stephany G Jones, Vladyslav V. Vyazovskiy +3 more
Sleep deprivation in the white-crowned sparrow increases the intensity of sleep as measured by SWA, and peak SWA in both SWS and NREM sleep increased significantly immediately following sleep deprivation relative to baseline.
