When awake, most people exhibit beta waves , the highest in frequency and lowest in amplitude, They are desynchronousthat is, the waves are not very consistent in their pattern. When relaxed most people exhibit alpha waves, which are slower, increase in amplitude and become more synchronous. The first stage of sleep is characterized by theta waves, which are even slower in frequency and greater in amplitude than alpha waves. Stages 1 and 2 are relatively "light" stages of sleep. A sleeper passes from the theta waves of stage 1 and 2, to the delta waves of stage 3 and 4. Delta waves are the slowest and highest amplitude brain waves. This is the deepest stage of the sleep cycle.
The next stage is REM sleep, a sleepers brain waves demonstrate characteristics that are similar to waking sleep, a combination of alpha, beta, and desynchronous waves. This is the stage of sleep most associated with dreaming.
In a normal night's sleep, a sleeper begins in stage 1, moves down through the stages, to stage 4, then back up through the stages, with the exception that stage 1 is replaced by REM, then the sleeper goes back down through the stages again. One cycle, from stage 1 to REM takes approximately ninety minutes. This cycle is repeated throughout the night, with the length of REM periods increasing, and the length of delta sleep decreasing, until during the last few cycles there is no delta sleep at all.

I would think beta particles are emitted from the brain during Rapid Eye Movement.

How can brain waves produced during REM sleep be described?
The frequency of your brain waves during REM sleep are beta (which incidentally occurs during the waking state as well). These are low voltage, high frequency waves.
What does not occur during a narcoleptic sleep episode?
Truly "deep" sleep does not occur during REM sleep. REM sleep is when you are dreaming. It is deeper than light sleep, but not as far down in unconsciousness as "deep" sleep.
Can brain waves produced during non-REM sleep be described?
Very long and slow A+
How can brain waves produce during non-REM sleep be described?
Very long and slow A+
How can brain waves produced during non rem sleep be described?
Very long and slow A+
REM sleep is characterized by what frequency and what amplitude brain waves?
High frequency and low amplitude.
What is slow-wave sleep?
Slow wave sleep occurs after Stage 1 and Stage 2 sleep, and prior to REM sleep. There is more slow wave sleep present toward the beginning of the night, while more REM sleep is present toward the end of the night's sleep. In slow wave sleep, delta waves are present on the EEG (Electroencephalogram), which measures brain activity. These waves are long and slow, as opposed to the sharp waves of Stage 2 sleep. It is ecause of the shape of these waves that the stage is called slow wave sleep.
What statements about rem sleep are true?
REM sleep is amazing sleep!
Why is REM sleep also called Paradoxical sleep?
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.
REM rebound involves the?
REM rebound involves the tendency for REM sleep to increase following REM sleep deprivation.
Is REM sleep a quiet or active sleep?
REM (Rapid Eye Movement) sleep is active sleep.
How tiring is REM sleep and how much time do you spend in it?
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.
