Chapter 5: Problem 1

A table here could have provided you with a systematic comparison of REM sleep and non-REM sleep, but that would have deprived you of the opportunity to check your understanding of these sleep phases by creating your own table. Try to fill in each of the blanks below with a word or phrase highlighting the differences between REM and nonREM sleep with regard to the various characteristics specified. As usual, you can find the answers in Appendix A. Characteristic \(\quad\) REM sleep \(\quad\) Non-REM sleep Type of EEG activity \(\quad\) ___________ \(\quad\) __________.

Short Answer

Expert verified
Question: Compare the EEG activity during REM sleep and non-REM sleep. Answer: In REM sleep, EEG activity shows mixed frequency, low-voltage signals, often called Theta activity or Sawtooth waves, resembling an awake state. In non-REM sleep, EEG activity differs based on the stage of sleep: N1 has low-amplitude, mixed-frequency activity; N2 shows K complexes and sleep spindles; and N3 presents delta activity with high-voltage, low-frequency waves. Overall, non-REM sleep exhibits slower and more synchronized brain activity compared to REM sleep.

Step by step solution

01

Study REM and Non-REM sleep

To fill in the table, first, understand the differences between REM (Rapid Eye Movement) sleep and non-REM sleep. REM sleep is characterized by rapid eye movements, muscle paralysis, and vivid dreams. Non-REM sleep is characterized by deeper sleep without rapid eye movements and is further divided into three stages (N1, N2, and N3).
02

Research EEG activity in REM and Non-REM sleep

Next, find information about the differences in the type of EEG (Electroencephalogram) activity associated with each sleep phase. The EEG is a diagnostic tool that measures electrical activity in the brain, which helps to identify sleep cycles.
03

Identify EEG Activity for REM sleep

During REM sleep, brain activity shows a pattern of mixed frequency, low-voltage signals in the EEG. This type of EEG activity is similar to that observed in the awake state and is often referred to as "activated" or "desynchronized" EEG. The primary activity observed in REM sleep is often called "Theta activity" or "Sawtooth waves."
04

Identify EEG Activity for Non-REM sleep

During non-REM sleep, brain activity shows a different pattern depending on the stage of sleep. In stage N1, you observe low-amplitude, mixed-frequency EEG; in stage N2, you notice more slowing with K complexes and sleep spindles; and in stage N3, you find delta activity with high-voltage, low-frequency waves. Overall, non-REM sleep shows slower and more synchronized brain activity compared to REM sleep.
05

Fill in the table

Now that you have the necessary information, fill in the blanks in the table. Characteristic \(\quad\) REM sleep \(\quad\) Non-REM sleep Type of EEG activity \(\quad\) Theta/Sawtooth waves \(\quad\) Stage-specific (N1: low-amplitude, mixed-frequency; N2: K complexes and sleep spindles; N3: delta activity)

From our discussion of the principal psychoactive drugs, it is clear that considerable overlap exists among the categories of drugs in terms of their medical uses, desired effects, and short-term side effects. Each type of drug, however, has at least one or two characteristics that make it different from the other types. Check your understanding of the unique characteristics of each type of drug by indicating which has the characteristics listed below. Choose from the following: (a) narcotics, (b) sedatives, (c) stimulants, (d) hallucinogens, (e) cannabis, and (f) alcohol. You'll find the answers in Appendix A. ______________ Used as a "sleeping pill" because it reduces CNS activity

Early in the chapter, we emphasized the intimate relationship between brain activity and variations in consciousness. Check your understanding of this relationship by indicating the kind of EEG activity (alpha, beta, theta, or delta) that would probably be dominant in each of the following situations. The answers are in Appendix A. You are playing a video game.
