Question

REM               nonREM paralysis          sleepwalking   rapid eye movement    twitches

In stage 3 sleep, slow high amplitude waves constitute 20% of the EEG. These DELTA waves predominate during stage 4. Also, heart rate, blood pressure, and breathing rate decrease. The sleeper will sleep through loud noises. Most DREAMING and NIGHT TERRORS occur in this stage. Collectively, stages 1 through 4 are referred to as _________ sleep.

After progressing through stages 1 through 4, the sequence reverses and the sleeper enters stage 3 and then stage 2. However, rather than enter stage 1, the sleeper enters _________ (REM) sleep. REM sleep is characterized by smaller, faster waves on the EEG, indicating brain activity similar to an awaken state. There are rapid eye movements, and fluctuations in heart rate, blood pressure, and breathing rate. Also, _________ occur (especially in the face and hands), and both sexes experience sexual arousal. When awakened from REM sleep one reports ___________ but when in REM sleep one cannot act out dreams because the body is in a ________. The sequence through nonREM stages lasts approximately 70 minutes and a REM episode lasts about 20 minutes. Thus, each sequence takes approximately 90 minutes. A sleeper completes the cycle through nonREM and REM several times a night, depending on how long one sleeps.   Also, the amount of time spent in each stage changes throughout the night. As sleep progresses, there is a decrease in the amount of time spent in delta sleep and an increase in the amount of time spent in __________ sleep.
