rem sleep or paradoxical sleep
Paradoxical
Paradoxical excitement or paradoxical sleep is a stage of sleep (during REM) in which the brain and body systems are active while the body is physically at rest. This excited stage while at rest is why it's a "paradox."
3/13/2012 jhh: REM sleep is NOT deep sleep. In fact, it is the lightest stage of sleep. In order from awake to deep sleep: AWAKE, REM, LIGHT, DEEP. Deep sleep and REM sleep are the most important stages though. Light sleep doesn't do much for you. Deep replenishes your body, while REM replenishes your mind. Older answer (not accurate): Yes. It is the deeper form of sleep that we experience during our sleep cycle, rem sleep is where dreaming occurs But not the deepest sleep, which would be delta. That's where, unless your a mother and hear your baby cry, you are oblivious to your environment.
our nervous system is highly active, while our voluntary muscles hardly move.
Because during a REM stage your brain produces waves with a frequency and amplitude similar to beta waves. Beta waves have short frequencies and low amplitudes. These are the waves that are most common when you are most awake. Basically: you look asleep, but your brain is wide awake. REM sleep is when we remember our dreams, so it makes sense that our brains are most active when we are dreaming, seeing as that dreams require a lot of mental activity.
In reality, REM sleep involves a mix of activity (bursts of eye movement and brain activity similar to alpha waves) and inactivity (body paralysis as the brain stem prevents cortex activity from reaching the rest of the body). This activity-paralysis mix gives REM sleep its other name: paradoxical sleep. Adults tend to spend about 20 to 25 percent of an average night in REM sleep. A person would be more likely to be exhausted by too little REM sleep than by too much.
REM sleep is amazing sleep!
REM rebound involves the tendency for REM sleep to increase following REM sleep deprivation.
REM (Rapid Eye Movement) sleep is active sleep.
Yes blind peole have REM sleep!!
There are 4 non-REM stages and REM sleep.
