a. .06 sec.
b. .6 sec.
c. .6 milliseconds
, EEG 101 Final exam Questions With
Solutions
d. 600 milliseconds a. .06 sec.
Duration = 1 divided by the duration
4.
All of the following are true of alpha EXCEPT
a. is a frequency of 9-10 Hz in the alert, awake adult
b. is seen in the posterior head regions
c. attenuates with eye opening and accentuates with eye closing
d. is frequently seen in the front-central regions of the alert, awake adult d. is frequently
seen in the front-central regions of the alert, awake adult
5.
What affect would changing the HF from 70Hz to 30Hz have on a spike and wave complex?
a. no affect
b. will decrease the frequency of the spike and wave complex
c. will decrease the amplitude of the slow wave
, EEG 101 Final exam Questions With
Solutions
d. will decrease the amplitude of the spike d. will decrease the amplitude of the spike
HF affects fast wave. Spikes are fast and change in the HF will decrease the amplitude of the
spike.
