Rapid eye movement sleep (REM sleep or REMS) is a unique phase of sleep in mammals (including humans) and birds, characterized by random rapid movement of the eyes, accompanied by low muscle tone throughout the body, and the propensity of the sleeper to dream vividly. The core body and brain temperatures increase during REM sleep and skin ...
REM rebound is the lengthening and increasing frequency and depth of rapid eye movement (REM) sleep which occurs after periods of sleep deprivation.When people have been prevented from experiencing REM, they take less time than usual to attain the REM state. [1]
Nathaniel Kleitman (April 26, 1895 – August 13, 1999) [1] [2] was an American physiologist and sleep researcher who served as Professor Emeritus in Physiology at the University of Chicago.

Then those cycles are broken into stages within two categories: NREM sleep (non-rapid eye movement sleep) and REM sleep (also known as rapid eye movement sleep). Your brain activity changes during ...
REM sleep is considered closer to wakefulness and is characterized by rapid eye movement and muscle atonia. NREM is considered to be deep sleep (the deepest part of NREM is called slow wave sleep), and is characterized by lack of prominent eye movement, or muscle paralysis. Especially during non-REM sleep, the brain uses significantly less ...
EOG (electrooculography), the measure of the eyes’ movement, is the third method used in the sleep architecture measurement; [7] for example, REM sleep, as the name indicates, is characterized by a rapid eye movement pattern, visible thanks to the EOG. [8]
During the following "non-rapid-eye-movement" sleep, the researchers introduced "auditory memory cues." When the participants woke, they had less memory of the negative images and stronger memory ...
