EEG 101 Final exam (Verified)
1.
_____ is seen in the central regions during Stage II sleep.
a. Beta
b. Theta
c. Sleep Spindles
d. Polymorphic Delta
c. Sleep spindles
2.
Which filter is used to eliminate artifact caused by electrical interference?
a. 10 Hz
b. 15 Hz
c. 35 Hz
d. 60 Hz
e. 70 Hz
d. 60 Hz
is specific in eliminating electrical or 60Hz artifact
3.
A spike that has a frequency of 16 Hz has a duration of
a. .06 sec.
b. .6 sec.
c. .6 milliseconds
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
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.
6.
Beta activity is
a. seen in the frontal regions of the alert, awake, relaxed adult
b. is frequently seen in the occipital regions during drowsiness
c. accentuates with eye opening
d. is always indicative of barbibuate use
a. seen in the frontal regions of the alert, awake, relaxed adult
7.
_____ is 1 divided by the duration of the wave in seconds.
a. duration
b. frequency
c. voltage
d. amplitude
b. frequency
8.
What is the basic functional and structural unit of the nervous system?
a. neuron
b. myelin sheath
c. electron

a neuron
9.
_____ is seen in drowsiness at frequency of 4-7hz
a. alpha
b. beta
c. theta
d. delta
c. theta
10.
A slow wave having three phases +,-,+ or -,+,- and that is seen in the variety of
metabolic disorders is
a. triphaisc
b. complex
c. transient
d. sharp
a. triphaisc
