activity at therapeutic doses?


Select one:
a. chloral hydrate
b. antidepressants

Since a common ground electrode
placement is at Fpz, ground lead recording
artifact usually manifests itself as
________________.


Select one:
a.Alpha at Fpz
b. Eye blink artifact in an illogical
location, where an electrode has high
impedance
c. rhythmic theta in the occipitals
d. 60 Hz at Fpz
Runs of notched theta in the 6 Hz range, a. This is a normal variant called RMTD, or Rhythmic Mid-temporal Theta Discharge.
appearing focally in the mid-temporals
over one or both hemispheres during
drowsiness and light sleep.


Select one:
a.This is a normal variant called RMTD,
or Rhythmic Mid-temporal Theta
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.
e.This is a normal variant called Mu rhythm.
Involuntary movements: (select all that A, B, C, D
apply)

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
