(also try: Drugs and Conscious Experience ) alpha activity | beta activity | delta activity | theta activity 1. The EEG record of a person in a state of "quiet relaxation" shows this kind of electrical activity. 2. During deep or slow wave sleep, this type of electrical activity is dominant. 3. The transition between sleep and wakefulness is marked by this kind of electrical activity. 5. The EEG record of a person who is in REM shows these two kinds of electrical activity. 6. Stages 3 and 4 sleep are marked by this kind of electrical activity. 7. Stage 1 sleep is marked by this kind of electrical activity. 8. The EEG recording of a person who is dreaming is most likely to show this kind of pattern of electrical activity (choose two) 9. The EEG person of a person who is moving about his or her room is most likely to show this pattern of electrical activity. 10. The EEG person of a person who is deeply asleep is most likely to show this pattern of electrical activity.
