Sleep architecture is the basic pattern of normal sleep. There are two main types of sleep. Non-rapid eye movement (NREM) and rapid eye movement (REM). NREM has three different stages, all of which have a different depth of sleep. They are identified by sleep experts through brain-wave patterns, eye movements and muscle tone.
REM sleep is a stage all by itself and is the stage of "dreaming". This can be identified through higher levels of brain wave activity and being as close to being awake as possible. Continue reading to find out more about what sleep architecture is and associated conditions when it is disrupted.
