EEG

a record of the electrical activity of the brain

2

Delta

below 4 Hz; slow, large waves; normally seen during deep sleep

3

Alpha

rhythm generally apparent when an individual is in a relaxed, nonattentive state with the eyes closed

4

Beta

correlated to the alert state; usually about 15 to 30 Hz

5

Alpha block

suppression of the alpha rhythm

6

Four types of brain lesions that may be determined by EEG studies.

epileptic foci, infections, tumors, abscesses

7

What is the common result of hypoactivity or hyperactivity of the brain neurons?

unconsciousness

8

How was alpha block demonstrated in the laboratory experiment?

By clapping your hands, which caught the attention of the subjects.

9

What was the effect of mental concentration on the brain wave pattern?

Should have increased the frequency of the brain waves from the level of the alpha rhythm.

10

What effect on the brain wave pattern did hyperventilation have?

Produced a fast, irregular pattern

11

Suggest the possible advantages and disadvantages of using electroencephalography in a clinical setting.

EEG is a useful tool in the clinical setting to assess cerebral activity in generalized brain regions. Because EEG is indirectly recording, via the scalp, the activity of millions of nerve cells simultaneously, it is less effective in assessing the function of very specific regions of the brain.
