ACNS Guidelines 3 Review
What is a montage? - answer Montages are logical and orderly arrangements of
electrode pairs (channels) to display EEG activity over the entire head.
What is the minimum number of channels in a montage? - answer16 channels
What are the three goals of a montage? - answer- display the EEG activity of the entire
head
- allow comparison of activity on both sides of the head
- help with localizing abnormal activity to a specific region
LB stands for what kind of montage? – answer Longitude bipolar
TB stands for what kind of montage? - answer transverse bipolar
R stands for what kind of montage? - answer Referential
True/False: ACNS recommends the tracings from the anterior electrodes be placed over
the posterior electrodes in a montage? - answer True
True/False: ACNS recommends the left sided leads be placed above the right sided
leads in a montage? - answerTrue
Temporal lobe epilepsy is suspected. You are recording in a referential montage. What
should the reference be? WHy? - answerCz as A1/A2 are close to the temporal lobe
and can pick up the seizure activity.
Your patient is sleeping. You need to record in a referential montage. What should the
reference electrode be and why? - answerA1/A2 are the better choice as Cz is right
where prominent sleep activity is occuring.
Identify the montage: Fp1-F7, F7-T3, T3-T5, T5-O1 - answerLongitundinal bipolar
Identify the montage: Fp1-Fp2, Fp2-F8, F7-F3, F3-Fz - answerTransverse Bipolar
Identify the montage: F7- A1, T3- A1, P7 - A1, O1 - A1 - answerReferential to the ear
Identify the montage: C4-Cz, C3-Cz, P4-Cz, P3-Cz - answerReferential to Cz
