    REM sleep is characterized by the lack of muscle activity. Physiological studies have shown that aside from the occasional twitch, a person actually becomes paralyzed during REM sleep. [7] In motor skill learning, an interval of sleep may be critical for the expression of performance gains; without sleep these gains will be delayed. [8]

    Sleep deprivation also has a documented effect on the ability to acquire new memories for subsequent consolidation. A study done on mice that were sleep deprived before learning a new skill but allowed to rest afterward displayed a similar number of errors on later trials as the mice that were sleep deprived only after the initial learning. [46]

    One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.

    Deficient sleep patterns are prominent in many psychiatric ailments. [18] Insomnia increases the risk of a depressive episode, sleep deprivation influences the onset of hypomania, and sleep disturbance contributes to the maintenance of mood disorders. [19] Amongst manic bipolar patients, sleep loss may act as a trigger in the onset of a manic ...

    Sleep-learning or sleep-teaching (also known as hypnopædia or hypnopedia) is an attempt to convey information to a sleeping person, typically by playing a sound recording to them while they sleep. Although sleep is considered an important period for memory consolidation , [ 1 ] scientific research has concluded that sleep-learning is not possible.
