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.

What type of brain waves are produce during sleep?
During sleep, different brain waves are produced depending on the sleep stage. For example, during REM (rapid eye movement) sleep, the brain exhibits beta and theta waves, while in non-REM sleep stages, delta waves are prominent. Delta waves are associated with deep sleep and are typically seen in stages 3 and 4 of non-REM sleep.
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.
REM sleep is characterized by what frequency and what amplitude brain waves?
High frequency and low amplitude.
Can brain waves produced 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+
How can brain waves produce during non-REM sleep be described?
Very long and slow A+
What statements about rem sleep are true?
REM sleep is amazing sleep!
REM rebound involves the?
REM rebound involves the tendency for REM sleep to increase following REM sleep deprivation.
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.
Is REM sleep a quiet or active sleep?
REM (Rapid Eye Movement) sleep is active sleep.
In Stage 4 sleep what type of brain waves do you have?
Delta Waves (APEX)
