Summary:Abbreviations: CREB, cyclic AMP response element-binding protein; EEG, electroencephalogram; GABA, gamma-aminobutyric acid; LTP, long-term potentiation; NREM, non-rapid eye movement; REM, rapid eye movement; SCN, suprachiasmatic nucleus; VLPO, ventrolateral preoptic If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process has ever made," Allan Rechtschaffen said. [...]constantly flying migrating birds and, more controversially, newborn whales (and their nursing mothers) may temporarily suspend sleep altogether without deleterious effects or need for catching up [4,5,15-17]. [...]both REM and NREM sleep appear vital and subject to homeostasis but can be suspended in rare cases for a substantial portion of life. [...]in mammals, REM sleep amount and length are lower in ungulates versus carnivores [19].
