Chapter 4: States of Consciousness

Question 1

Beta Waves

Answer 1

While Awake
High Frequency
Lowest Amplitude

Question 2

Frequency Waves

Answer 2

How many brains waves occur in a second

Question 3

Amplitude Waves

Answer 3

Height of the brain wave

Question 4

REM

Answer 4

Rapid Eye Movement. Beta waves. Dreams happen here. No movement. Paralyzed. MEMORY AND LEARNING.

Question 5

NREM

Answer 5

3 Stages: Transitional, between awake and sleep. Deep state of relaxation. Deep sleep/slow wave sleep

Question 6

Stage 1 NREM

Answer 6

Transition between awake and asleep. ALPHA WAVES. Resembles someone who is relaxed but awake
Theta waves
Easy to wake someone. They may say they weren’t sleeping.

Question 7

ALPHA WAVES

Answer 7

Resembles someone who is very relaxed yet awake. A part of Stage 1 NREM. Low in frequency, high in amplitude.

Question 8

Stage 2 NREM

Answer 8

Deep state relaxation. Sleep spindles and K-complex.

Question 9

THETA WAVES

Answer 9

Seen in stage 1 NREM. Even lower frequencies than alpha, and higher amplitude than alpha.

Question 10

Sleep spindles

Answer 10

rapid bursts of higher frequncy.

Question 11

K- Complex

Answer 11

Very high amplitude. Occurs in response to environmental stimuli. Serves as bridge to environmental changes.

Question 12

Stage 3 NREM

Answer 12

Deep sleep or slow wave sleep. DELTA waves. Heart rates slows. Respiration slows. Difficult to awaken.

Question 13

DELTA WAVES

Answer 13

Lowest frequency, highest amplitude.

Question 14

Reticular Activating System

Answer 14

In midbrain. Regulates sleep/wake cycle.
