It is for measuring the amplitude of frontal activity and recognition of N3.
The manual however forgot to clarify if N3 was to be scored from the frontals.
I have an email at work from the aasm saying to continue to score from the centrals – I’ll post it Monday.
I don’t have my manual here at home so I don’t recall if there other justifications/reasons or not. I recall it also mentions Kcomplexes will be more readily recognizable from the frontals.
There will be a course devoted to this in Dec:
