Montages

Question 1

What is an EEG montage?

Answer 1

It is a layout of electrode positions on the scalp that is amplified and used to record electrical activity in the brain

Question 2

What are the two main types of montages

Answer 2

Bipolar and referential

Question 3

What type of brain activity are bipolar montages useful for?

Answer 3

For identifying lateraled and generalized brain activity

Question 4

Which type of montage is useful for identifying changes in brain activity over time

Answer 4

Referential montage

Question 5

Name three types of bipolar montages?

Answer 5

Double banana; transverse, hat (or circumferential)

Question 6

Name three types of referential montages?

Answer 6

Referential average, ipsilateral, contrateral

Question 7

What is a double banana montage?

Answer 7

It is a longitudinal bipolar montage that records activity from electrodes placed on the left and right hemispheres of the brain. It is useful for identifying lateralized and generalized brain activity

Question 8

What is a transverse montage?

Answer 8

It is a bipolar montage loosely referred to as the sleep montage that records activity from the central electrodes that highlight sleep

Question 9

What is a hat (circumferential) montage?

Answer 9

It is a bipolar montage that records activIty around the circumference of the head and useful for identifying end of chain activity

Question 10

What is end of chain activity?

Answer 10

**

Question 11

What is a referential average montage?

Answer 11

It is a referential montage that averages the activity from on all of the Electrodes on the scalp and it is useful for identifying focal activity
