Discharge.
b. This is a normal variant called 14 and 6 Hz positive spikes. Incorrect
c. This is likely an artifact caused by movement of the tongue.
d. This is an abnormal epileptogenic pattern.

In the Illustration, the same data is modified and reformatted in the second
sample. What parameter changed in the following sample? How does this help?
Select one:
a. Decreased sensitivity to better resolve the spikes
b. Increased time base (analysis time/display time/epoch) or decrease paper
speed, to scrunch up the waveforms to better resolve focal slowing
c. Decreased time base (analysis time/display time/epoch) or increase equivalent
paper speed to spread out the waveforms to better resolve the fast activity and
spikes.
d. Increased sensitivity, to better resolve the low amplitude activity Incorrect
