It includes the following topics: ! sleep as an active process and brain areas that turn it on ! the EEG: how it is recorded and what it shows about brain activity ! the EEG for the two basic kinds of sleep, slow wave sleep (SWS) and rapid eye movement sleep (REM) and their associated physiological and psychological processes ! the division of SWS into four stages ! the alternation between SWS and REM sleep during a night's sleep ! developmental changes in sleep
