8. Outline the nature of sleep
Key detail from the mark scheme
The nature of sleep conventionally refers to the basic characteristics of sleep. These include its circadian periodicity, the different phases and stages of sleep (REM and NREM, or REM and SWS), the association between REM sleep and dreaming etc.
Different sleep patterns across the lifespan or across the animal kingdom would also be relevant.
Given the problem of defining the ‘nature’ of sleep, a wide range of material could be relevant. These include the functions of sleep, sleep disorders, brain mechanisms of sleep and sleep as a biological rhythm.
