  2. Effects of sleep deprivation on cognitive performance

    en.wikipedia.org/wiki/Effects_of_sleep...

    Animal studies have partly validated these claims. For instance, one study conducted with rats showed that REM sleep deprivation after learning a new task disrupted their ability to perform the task again later. This was especially true if the task was complex (i.e., involved using unusual information or developing novel adaptive behaviours). [38]

    en.wikipedia.org/wiki/Neuroscience_of_sleep

    Sleep deprivation studies show that sleep is particularly important to normal brain function. Sleep is needed to remove reactive oxygen species caused by oxidative stress (and generally autophagy) and to repair DNA. REM sleep also decrease concentration of noradrenaline, which when in excess amount causes the cell to undergo apoptosis.

  4. REM rebound - Wikipedia

    en.wikipedia.org/wiki/REM_rebound

    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 ]

    The study also suggests that rapid-eye movement (REM) sleep, where dreaming occurs, may be crucial to the ‘housekeeping’ of the brain by maintaining the ability to keep unwanted memories and ...

    One study suggests that taking longer to reach the rapid eye movement (REM) stage of sleep is associated with biomarkers of Alzheimer’s disease. The delay in getting to REM might be useful in ...

  7. Rapid eye movement sleep - Wikipedia

    en.wikipedia.org/wiki/Rapid_eye_movement_sleep

    Sleep deprivation studies have shown that deprivation early in life can result in behavioral problems, permanent sleep disruption, and decreased brain mass. [ 78 ] [ 57 ] The strongest evidence for the ontogenetic hypothesis comes from experiments on REM deprivation, and from the development of the visual system in the lateral geniculate ...

  8. Sleep and learning - Wikipedia

    en.wikipedia.org/wiki/Sleep_and_learning

    This study gives evidence that REM sleep is a significant factor in consolidating motor skill procedural memories, therefore sleep deprivation can impair performance on a motor learning task. This memory decrement results specifically from the loss of stage 2, REM sleep. [11]

    Randy Gardner (born c. 1946) is an American man from San Diego, California, who once held the record for the longest amount of time a human has gone without sleep.In December 1963/January 1964, 17-year-old Gardner stayed awake for 11 days and 24 minutes (264.4 hours), breaking the previous record of 260 hours held by Tom Rounds.
