Document Summary

It picks up brain waves (brain activity), by detecting the electromagnetic radiation with electrodes on the head. After experimentation, it was discovered that there are three types of brain waves, corresponding to the five stages of sleep. Progressively more delta waves slow-wave sleep (sws) In stage 3 delta waves occur less than 50% of the time. In stage 4 delta waves occur more than 50% of the time. Sonabulism is the official term for sleep walking. Eeg patterns resemble those of people who are awake. Breathing is choppy and heart rate fluctuates. Motor activity is practically eliminated, and the person is almost paralyzed. Paradoxical sleep: the internal organs are quite active, while the body seems paralyzed. Lucid dreaming: being aware that you are dreaming, and therefore can control the dream. Most rem sleeps occurs later in the night with each succeeding rem period being longer than the preceding one.
