原文:Weare so familiar withthe factthatman ages,thatpeople have for years assumedthatthe process of losing vigour with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. 我们对人总...
While this is occurring, your body slows down in preparation for NREM stage 3 sleep and REM sleep—the deep sleep stages when the brain and body repair, restore, and reset for the coming day.1 NREM Stage 3 Deep, slow brain waves known as delta waves begin to emerge during NREM stage 3...

The two-process model of sleep regulation revisited. Aviat Space Environ Med 2004; 75:(3, Suppl) A3743.The two-process model of sleep regulation posits that the interaction of its two constituent processes, a sleep/wake dependent homeostatic Process S and a circadian Process C, generates the ...
Sleep improves preferentially the consolidation of memories that were encoded explicitly and are behaviourally relevant to the individual. Consolidation during sleep not only strengthens memory traces quantitatively but can also produce qualitative changes in memory representations. An active process of re-...
When it comes to the sleep definition itself, we know it helps us to rest, but what actually is sleep. What is our body doing when it happens? What we do know is that various areas of the brain are part of the sleep process: Hypothalamus –a tiny part of the brain that is filled...
Modern scientists divide the process of dying into two stages --- clinical( 临床的 )or temporary( 暂时的 )death and biological death. Clinical death occurs when the most important organs such as the heart or lungs have ceased( 停止 )to function but have not suffered permanent( 永久的 ) dam...
