| | Sleep Stages - Sleepchannel.com |
 | | Sleep stages are monitored and examined clinically with polysomnography, which provides data regarding electrical and muscular states during sleep. | | | Sleep quality changes with transition from one sleep stage into another. | | | Rapid eye movement (REM) sleep is marked by extensive physiological changes, such as accelerated respiration, increased brain activity, eye movement, and muscle relaxation. |

| | REM Sleep |
| | REM sleep and dreaming are triggered by the pons and neighboring structures in the brainstem. | | | The earliest hints that sleep was a changing state came with studies showing that blood pressure, heart rate, and other body functions in humans rise and fall in a pattern during sleep. | | | Exactly what sleep does for humans is unknown. |

| | Current Ideas about REM Sleep, Dreams and Dreaming: | | | Except for the length of the dream report, sleep-onset non-REM dream reports and REM dream reports are identical. | | | But the dream state (a dopaminergic mechanism) is driven by our wishes. |

| | REM sleep |
| | This study differs from other rat sleep experiments because the animals were allowed normal sleep patterns. | | | A number of scientific observations have supported the idea that the brain is reactivated during sleep to process sensorimotor information, but how the brain did this remained unknown. | | | Other labs have looked at the difference between rats that are sleep deprived and rats that sleep normally. |

| | The evolution of REM sleep |
| | The number of studies of amphibian and reptilian sleep is miniscule, with few such studies using rigorous electrophysiological and behavioral indices. | | | Without behavioral observation, REM sleep periods might be mistaken for waking. | | | This deep sleep is consistent with its very safe sleep condition, in a burrow that few predators have been able to gain access to. |

| | Neuroscience for Kids - Sleep |
| | This theory of sleep suggests that sleep helps the body recover from all the work it did while an animal was awake. | | | While we are asleep, our brains are on a bit of a "roller-coaster" through different stages of sleep. | | | This also means that sleepwalkers are not in REM sleep and are not acting out their dreams. |

| | GABAA receptor antagonism at the hypoglossal motor nucleus increases genioglossus muscle activity in NREM but not REM ... |
| | Such studies will also be important in guiding therapeutic strategies for obstructive sleep apnoea to determine if the pharyngeal muscles can be selectively activated in sleep, especially REM sleep. | | | Bicuculline at the hypoglossal motor nucleus increased GG activity in wakefulness and NREM sleep, but no such increase was observed when REM sleep was analysed as a whole. | | | The results of the present study show, however, that despite the increase in GG activity in wakefulness and NREM sleep with bicuculline, GG activity was minimal upon transition into REM sleep and remained effectively abolished in those REM sleep periods without phasic twitches in the GG muscle. |

| | REM Behavior Disorder: When Your Dreams Become Reality |
| | What we call "sleep" involves transitions between three different states: wakefulness, rapid eye movement (REM) sleep, which is associated with dreaming, and non rapid eye movement (N-REM) sleep. | | | "REM behavior disorder underscores the importance of basic science research in animals," says Mahowald, "because without the information obtained in basic science animal research, the disorder could never have been identified. | | | The only sensations the sleeper experiences are what is occurring in their dream. |
