The stage of sleep marked by rapid eye movements, dreaming, and paralysis of motor systems. go to glossary index
the stage of sleep associated with rapid eye movements, an active brain-wave pattern, and vivid dreams. (201)
Rapid Eye Movement sleep is the second general phase of sleep during which the brain activity is similar to brain activity during wakefulness. Dreaming is common in REM sleep.
rapid eye movement sleep; the stage of sleep in which dreaming occurs
Approximately three to five times per night or every 90 minutes, a normal sleeper experiences several minutes of REM sleep during which dreaming occurs. In REM sleep, the activity of many brain systems equals or exceeds those when in active waking; however, muscle atonia prevents motor activity and noradrenergic, serotonergic and histaminergic neurons become silent. REM sleep makes up about 20% of total sleep time.
Rapid-eye-movement sleep, characterized by movement of the eyes under the lids; often accompanies dreams.
a recurring sleep state during which dreaming occurs; a state of Rapid Eye Movements during sleep
Rapid eye movement sleep. REM sleep occurs in brief spurts of increased activity in the brain and body. REM is considered the dreaming stage of sleep. It is characterized by the darting of the eyes under the eyelids.
sleep during which the person experiences rapid eye movements
also known as "paradoxical" sleep, this state of sleep is characterized by rapid eye movement (REM), muscle paralysis, and irregular breathing, heart rate, and blood pressure. Dreaming takes place during REM sleep.
REM sleep is the portion of sleep when there are rapid eye movements (REMs). See the entire definition of REM sleep
Rapid Eye Movement sleep The period of sleep known as rapid eye movement sleep, when dreaming seems to occur.
The period of sleep that is associated with dreaming, rapid eye movements (REM), and certain involuntary muscle movements.
A sleep state characterized by dreaming, skeletal muscle relaxation, and rapid eye movements.
Rapid Eye Movement Sleep. Rapid eye movements are a normal characteristic of the level of sleep during which dreaming occurs. It is associated with extremes of muscle relaxation, which could bring on sleep apnoea, if it were to occur at all. Also seen in excess quantities in narcolepsy.
Rapid eye movement sleep in humans; it occurs every 90-100 minutes during sleep.
this is a light sleep when dreams occur and the eyes move rapidly back and forth.
The type of sleep characterized by rapid eye movements, an EEG indicative of high cortical arousal, speeded heart rate and respiration, near-paralysis of limb muscles, and recall of highly visual dreams.
The sleep state in which vivid dreaming occurs. About 25 percent of sleep is REM sleep, which first occurs about 90 minutes after falling asleep and is characterized by a shut down of muscles, relaxed bodies, irregular breathing and heart rate. REM Sleep Behavior Disorder is characterized by the lack of muscle paralysis during REM sleep, during which the individual acts out the ongoing dream.
Rapid Eye Movement Sleep Rapid eye movement sleep is recurring sleep state during which dreaming occurs. Sleep is a periodic state of rest during which consciousness of the world is suspended. The most significant characteristic of sleep, which differentiates it from the waking state, is the interruption of perception; a sleeping person does not see or hear.
