Document Summary

Human sleep exhibits different stages: how much do we sleep, and when, we do our most vivid dreaming during rem sleep. Study questions: the use of scalp electrodes to detect brain electrical activity is called eeg, which is short for electroencephalography. The recording of muscular activity is called emg, which is short for electromyography. Eye movements occurring during sleep are recorded using eog, which is short for electro-oculography. Used together, these techniques revealed to researchers that there are two main classes of sleep: slow-wave sleep, abbreviated sws, and rem sleep: a person moving from complete wakefulness to full sleep progresses through four distinct stages of sws. Complete the following table, giving the eeg characteristics of each stage. Fully awake 15 to 20 hz beta activity. Stage 1 sws 9 to 12 hz alpha rhythm. Stage 2 sws 12 to 14 hz sleep spindles. Stage 3 sws large amplitude delta waves, 1 per second.
