Summary
People may believe sleep to be simply a static state that is the direct opposite of wakefulness; however, this is not the case. Rather, it is a complex and dynamic process, and throughout sleep we progress through multiple stages that can be measured discretely across behavioural, physiological, and cognitive domains. This chapter describes the differences and features of these different stages and how they can be measured. Also described is the fact that sleep and wakefulness are not mutually exclusive, and that there are times when the lines between sleep and wake can be blurred, and this is notably true in insomnia. Finally, the chapter explains how sleep is regulated through interacting homeostatic and circadian processes, and the neuroscientific underpinnings of the sleep and circadian system.
