Brain Activity

Question 1

Electrical patterns observed on an EEG.

Answer 1

Brain Waves

Question 2

A printed report of the electrical activity of the brain.

Answer 2

Electroencephalogram (EEG)

Question 3

Occur in the brains of healthy, awake adults who are resting with their eyes closes.

Answer 3

Alpha waves

Question 4

Higher-frequency waves that appear in people who are concentrating on a task, under stress, or in a state of psychological tension.

Answer 4

Beta waves

Question 5

Brain waves that appear transiently during sleep in normal adults.

Answer 5

Theta waves

Question 6

Brain waves normally seen during sleep.

Answer 6

Delta waves

Question 7

Encompasses perception of sensations, voluntary initiation and control of movement, and capabilities associated with higher mental processing.

Answer 7

Consciousness

Question 8

Part of sleep that occurs in four stages.

Answer 8

Non-Rapid Eye Movement (NREM) Sleep

Question 9

Occurs after the fourth stage of NREM has been achieved. Vital signs increase, skeletal muscles (except ocular muscles) are inhibited. Dreaming takes place.

Answer 9

Rapid Eye Movement (REM) Sleep

Question 10

Relaxation begins. EEG shows Alpha Waves

Answer 10

Stage 1 NREM

Question 11

EEG is irregular with sleep spindles.

Answer 11

Stage 2 NREM

Question 12

Sleep deepens. Theta and delta waves appear.

Answer 12

Stage 3 NREM

Question 13

EEG is dominated by delta waves.

Answer 13

Stage 4 NREM

Question 14

Neurological disorder characterized by extreme daytime sleepiness and sudden attacks of sleep.

Answer 14

Narcolepsy

Question 15

Chronic inability to obtain the amount or quality of sleep needed to function adequately during the day.

Answer 15

Insomnia

Question 16

Temporary cessation of breathing during sleep.

Answer 16

Sleep Apnea

Question 17

Becomes inactive during sleep, preventing motor activity by preventing stimuli from reaching the spinal cord.

Answer 17

Locus Coeruleus

Question 18

The storage and retrieval of information

Answer 18

Memory

Question 19

Fleeting memory of the events that continually happen

Answer 19

Short-Term Memory

Question 20

Memory that is retained

Answer 20

Long-Term Memory

Question 21

Entails learning explicit information. Involves the hippocampus, amygdala, thalamus, hypothalamus, ventromedial prefrontal cortex, and the basal forebrain.

Answer 21

Fact Memory

Question 22

Motor activity acquired through practice. Involves the corpus striatum, premotor and motor cortexes.

Answer 22

Skill Memory

Question 23

Define electroencephalogram.

Answer 23

A printed record or graph of the electrical activity of the brain.

Question 24

Name and describe the four wave types associated with an EEG.

Answer 24

1. Alpha waves: characteristic of normal resting adults.
2. Beta waves: characteristic of a person who is concentrating.
3. Theta waves: observed in children and frustrated adults
4. Delta waves: found in a person who is sleeping deeply, in infants, or in people with damaged portions of the brain.
