Abstract:
This article discusses normal human sleep. Discoveries leading to an understanding of human sleep, electroencephalographic definitions, and general characteristics of normal human sleep are presented. Actuarial data for a first laboratory night are provided. Finally, the mechanisms governing sleep and wakefulness are reviewed and a model of normal sleep mechanisms going awry is outlined as an aid for understanding abnormal sleep associated with sleep disorders.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
