Delta waves Study guides, Revision notes & Summaries

Stages of sleep : 1, 2, 3, 4 (all NREM) and REM Stage 1 sleep : light sleep, muscle activity slows down, occasional muscle twitching NREM Stage 2 sleep : Breathing pattern and heart rate slows, decrease in body temperature NREM Stage 3 sleep : Deep sleep begins, slow delta waves generated NREM Stage 4 sleep 2 | P a g e : very deep sleep, rhythmic breathing, limited muscle activity, brain produces delta waves REM sleep : Brainwaves speed up, dreaming occurs, muscles relax, heart rat...

At 1:00 A.M. Luis gets out of bed and begins to sleepwalk. An EEG of his brain activity is most likely to indicate the presence of: - Delta Waves At 3 o'clock in the morning, John has already slept for four hours. As long as his sleep continues, we can expect an increasing occurrence of: - REM Sleep 40 year old Lance insists that he never dreams. Research suggests that he probably: - Would report a vivid dream if he were awakened during REM sleep Nightmares occur in - REM Sleep A woman b...
