Document Summary

Picks up electric activity in the brain. Stage 1(nrem 1) lightest stage of sleep lasts about 10mins. Stage 3 & stage 4 (nrem 3) Stage 3( delta waves occur less than 50% of the time) Stage 4( delta waves occur more than 50% of the time) This stage is often called slow wave sleep( sws) Eeg resembles those of an awake person. Motor activity is practically eliminated (sleep paralysis) Able to control the course/path that your dream takes. You can train yourself to do it. Difficult to wake someone when they are dreaming, unable to move physically, but their brain and internal organs are very highly activated. Pattern of stages of sleep; go down to stage 4, then back up to stage 2( where you hit a rem period) then go back down to stage 4. Longest periods are in the morning( dreams that you tend to remember) More common in men than women( 11% men vs. 4% women)
